Probably one of the most sought after activities in HS is bossing. While for the lower lvl ones it is as easy as point and shoot, for the big bad ones it require alot of coordination and every group member needs to do his job at the right moment.
For the brood bosses and up, you want to bring along these chars and act as it follows:

TKR
Your key group member, most of the times makes the difference between victory and defeat.
Has to:
- always keep group buffed ( augment and preferable might too  )
- yank group or dead members back into fight
- decelerate boss and surrounding mobs ( key debuff )
- weaken boss
- heal merc / engies and anyone else who needs it

Engineers
Them on second position as need for bossing, same as TKR they make the difference.
Has to:
- focus on repair ( even if no crew, as long as the target is repaired and kept alive, you have a chance )
- heal whenever possible, if not , keep repairing

Mercenary
As of now, it is needed only for high lvl bosses, mid ones are doable without a merc, still for the new formed groups it is a must.
Has to:
- be able to stay alive as long as possible ( keep retreat and sustain on at all times )
- provoke boss and surrounding mobs at all times ( keep them off your engies  so they can do their job )
- heal self or group members when needed

Pyro
Your preferate damage dealer, the quicker they dish damage out, the less work for others.
Has to:
- always cast amplification aura before major buffs
- when shields down, cast decimate till out of psi then fire bolt or wait for more decis
- heal merc and engies while psi is building up

Path
Excellent for more dmg, debuff and crowd control.
Has to:
- always cast compromise on boss , sometimes makes the difference for all other group members' casts to land , less resists
- stun additional mobs till group can take care of them
- psi regen all psi classes
- heal merc and engies when needed

Smug
Excellent for more dmg, can hold aggro while group recovers if needed.
Has to:
- time ambushes right, preferable with obfuscate on, as it will draw alot of aggro
- obliterate boss when TKR is busy and can't cast weaken
- impede boss when TKR is busy and can't cast decelerate
- take additional mobs off engies when needed
- heal merc and engies when needed

As long as every member keeps an eye on everyone else and cast accordingly, there is nothing that can go wrong. It is advised to have at least 2 engineers in group, makes life easier.
No AFK accepted during fight, when people ask or demand some action, do it ASAP. ( most probably you'll see people shouting "heal / rep / debuff / mob". )

After boss is dead, it is preferable to share loot on a need basis. ( Even tho we all are greedy, including me )
Eg. if TKR needs that sa20 malixs to improve his overall survival, give it to him. Gear up the chars in the same order as listed above.
Try to build up the ship armor of all group members, it is the primary stat you're looking after.

Fabrication in HS is pretty much like crafting and follows couple rules, still sometimes it is not easy to tell how and why you can or can't improve your items.

General

To open fabrication window type /fabricate or double click fabricate in actions tab.

What you can do:
- improve weapons (increase damage,  decrease delay, add effect)
- improve systems (increase existing stats, add new stats)
- create new ammo or fuel
- create new weapons and systems

What you need:
- alot of time
- weapon/system you want to modify
- specific parts that drop from mobs
- upgrade kits (can be bought from starbase lvl2 shops)
- enchanting stones (drop from bosses)
- tech requirement reducing stones (drop from bosses)

Recipes:
- alpha fabs - check other guides
- plussing - you need 2 items that have same id and 1 upgrade kit. To know what type of kit you need select item and press Activate. Eg. Put together in fabrication window, not stacked: stella bay, stella bay, simple kit then press fabricate.
- enchant - fab together item and stone
- create new weapons - weapon core, weapon mold, conduit, skill (skill optional, all other required)
- create new systems - system mold, conduit, system attributes (up to 4 sys attribs, you have to match location with mold)

Limitations:
- you can only stone an item ONE time
- systems with 4 stats cannot be stoned
- you can plus an item up to +9
- created items cannot be stoned
- items bought from starbase shops cannot be modified
- ALL plussings have a max of 95% success rate

Weapons

It is recommended to farm for materials and money before you start fabricating as upgrading kits will be expensive in the long run.
Raising skill can be done via plussing, stoning or new fabs.
General plussing: weapon weapon kit
Tech needed for high success chance can be found in the brackets if you activate a weapon (weaponery skill 14)  eg. or you can check weapons lvl then add 10%, rounded down.( For example to plus a lvl55 brekkar laser you will need 55+10%=55+5.5=55+5=60 skill for high  success chance.)
On every plus you will gain a 10% damage bonus, rounded down. Eg. 25/30 wep will gain 25*10%=2.5=2 so +1 of that will be 27/30. However, the next plus, formula is applied again on BASE stats (25/30) so at +2 we have: 25*20%=5 so wep will be 30/30. (Not 29/30 as when you add 10% rounded down again) So keep in mind that leftovers carry over plusses but will only be added when them reach 1. (0.9 will still be discarded)
You will gain skill from plussing a weapon up to 10.0 skill over the required skill. Eg. While plussing brekkars to +1 you can gain skill up to 70.0 (60.0 needed) - this needs more testing but looks to be true from observation.
Stoning a weapon will raise a weapon's lvl if dmg raised or delay reduced. However adding effect to a weapon can lower its lvl as some weps have their lvl rounded up.(eg. brood laser is lvl50 but when stoned with effect will change to lvl49)
Quantum stone - reduces tech needed by 33%
Infusion stone - reduces tech needed by 50%
You can plus a higher tech weapon by adding one quant/infusion stone into the fab: wep wep kit quant. Eg. you need 64 tech to plus Bxirs but you only have 50.0 skill. When you add the quant stone, your new tech requirement will be 64-(64*33%) or 64*0.67 for easier math = 42.0. Success
You cannot use quant/infusion stones to stoning fabs, only to plus.
Always keep in mind that for a tech 50.0 fabrication, if you have 50.0 skill, your success chance is 80%. You can raise this chance with intelligence stat (every 5 INT adds 1%) or with stats on weapons (new fabs) but will never be higher than 95% for plussing.
Stoning success chance can go up to 100% and it is the same for all items regardless their lvl(boosted for items under lvl30). Eg. you have 50.0 skill and 40 INT. Stoning a weapon lvl50 or a weapon lvl142 have the same success rate = 50% from skill + 40/5 from int = 50+8 = 58%.
If you plus a weapon then stone it, you can still plus it further. Note: on more plussing, bonus added will still be the one from original weapon, not from stoned weapon.
New fabrication weapons are divided in 2: ammo based (launcher and bay) and energy based (all others).
Ammo based: ballistic framework + launcher/bay mold + conduit + skill
Energy based:  molecular coil + beam/disser/bolt mold + conduit + skill
Skill added is optional.
You have to match weapon's core lvl with the conduit.
Skill have an increase of 15 lvls for every +1 skill. Eg. if you want to add +3 tactics on a new weapon, that will require weapon core+conduit to be higher than lvl45 (because +3 tactics require 3*15= at least lvl45).
Skills for weapons drop only from bosses as of now.
You cannot add wep cores or skills to already existing weps, only create new ones with them.
Tech skill needed to make new fabs is generally wep cores lvl +5. (Eg. For wep core lvl53 you need 58 tech).

Systems

All rules from weapons (plussing and stoning) apply to systems too.
While plussing systems, all stats existing on an item will get a 10% increase. Eg. Dread plate: 25sa 25off 2 rech 10def. +1 will be 27sa 27off 2 rech 11 def. At +2 we have 30sa 30off 2rech 12def. So, to gain 1rech more, we need the plate at +5(for the 0.2 increase per plus to add on plate).
Plussing cloaks will decrease cloaking time by 5%. Eg. Cloak 10sa cloak100 will be at +1 11sa cloak95.
Pick your systems wisely as 4 stats items cannot be stoned.
New fabs: sys mold + conduit + sys attrib
You can add up to 4 attribs to a newly created system, tho them must be all uniques (eg. you cannot add 2 hull attribs to same item).
You have to match highest sys attrib's lvl with the conduit. (Eg. comp mold + sys attrib lvl30 + sys attrib lvl48 + conduit lvl41-51).
You have to match all sys attribs location with mold. (Eg. You cannot add an attrib that has location sensor to a computer).
  You cannot add sys attribs to already existing systems, only create new ones.
Tech skill needed is generally highest sys attrib's used lvl +5. (Eg. Attribs 20/34/60, we take into account the lvl60 attrib so you need 65 tech).

You can try all fabrications with lower tech skill in the hope of skill gain, not recommended if you wish to keep the end product, as success chances will be lower.

To be updated.

Ok, so you decided to play Hostile Space Revived. Welcome

After you installed the client and created your brand new character, it is time to connect to the server.

First contact

Your game loaded up for the first time, it might be a bit confusing but let's see it step by step:

- you are prompted to choose a class, which are as follows:

    - Pyrokinetic - Psionic class, good damage, most spells are for improved damage ( and a defensive spell ), needed for bossing
    - Telekinetic - Psionic class, moderate damage, very useful for his ability to greatly increase ship armor and gather group members, a must for bossing
    - Telepath    - Psionic class, good damage, crowd control abilities, regenerating spells, highest entity ( companion ) in game, moderately needed for bossing
    - Mercenary   - Power class, your regular tank, moderate damage, it has increased hull and crew, a must for bossing
    - Engineer    - Power class, healer, low damage, pretty much keeps anyone alive, a must for bossing
    - Smuggler    - Power class, good damage dealer, ability to cloak and ambush ( best 1 hit damage ), bit squishy, moderately needed for bossing

- you are prompted to choose a race:
- Eschar - power regen bonus ( good for power classes, especially smuggler, otherwise not recommended )     
- Terrix - offense bonus ( good for damage dealer builds, all classes )
- Gi'pok - crew regen bonus ( good for bossing characters, esp. mercenary and engineers )
- Human  - psi regen bonus ( good for psi classes, if you plan to keep fighting without stops )
- Kalarix- defense bonus ( good for all classes, defensive builds, esp. mercenary, engineer)
- Tekorus- hull regen bonus ( good for all classes, regenerative builds, esp.engineer)

- you are prompted to choose a faction, only one active right now, so can't miss it
- choose an avatar you like.

Screen

At all times, your ship will be in the center of the screen, top-down view (yes, this is a top-down view game).
On the lower part of the screen, you'll see the HUD, where you can find all types of info about your ship, skills, commands, psions and
also game settings. ( You can show/hide this HUD at any time by pressing TAB or shift+I )

Ship tab:

Left side: you see your ship, with slots for weapons and systems.
Middle side: there is the cargo of your ship, where you
carry items while navigating around. Now you can see couple weapons and fuel there( hydrogen ) as well as some ammo. Try and equip them,
see which item goes where on the slots. ( As of now, you can only equip 2 weapons).
Middle right: If you select one item, on the right side of the cargo you will see information about that item. Read it to learn about it.
Far right of your HUD you will see a scanner, which shows you at all times surrounding ships and points of interest ( docking locations, looks like flashing red rectangles).
Enemy ships are marked with red triangles, friendly ones with white.
( If in close enough range, you can select them on the scanner, the info available will appear on the info screen where
you studied your items). Click on the Scanner button to activate it.

Info tab:

Here you will find all your available (or not) skills.
On the left side: you see information about your character, including class/race you already picked.
Wealth you earn as you sell items, it is always noted in the 50k0 format ( that means 50.000), eg. 2million credits will be 2000k0.
Under you see your main stats, strength, intelligence and dexterity. These ones you will never be able to change so choose wisely.
Strength - affects how much crew you gain per level, chance to interrupt an enemy and be interrupted by one. ( Important: if you run out of crew, your weapons won't fire and you won't be able to cast any ability )
Intelligence- affects how much psi you gain per level (mana in other games), affects skill gain rate, affects fabrication (crafting) chance of success (1% chance gain for every 5 int stats)
Dexterity - adds offense/defense per stat point.

You may want to read specific class/builds guides (coming soon) before raising those stats or just go for it if you know what you want.
Middle: Here are your character skills, based on your class choice.

Actions tab:

Here you will find all your available commands and psions.
White ones are not consuming any energy, blue ones are power consuming, pink ones are psi consuming.
White are the same for all characters, only ones that differ from class to class are blue and pink.
As you level up and increase your skills from the info tab, more actions will be available.

Options tab:

You can turn different options on and off here. ( Hint: leave shouting channel always on, so you can interract with others via general chat )
Quit tab: pretty obvious.

Take your time and learn the HUD, it will help you alot thru your HSR journey.

On the top right side of the screen you will see regenerating bars (power,hull,psi,crew) and your avatar. As you play the game, always
keep an eye on these bars so you can time your actions right (and not end up dead)

Top middle, there a live ping bar (bugged) and under it you will see at times the coordonates you are flying to.

Between the ping bar and your avatar, there is an experience bar where you can track your leveling progress.

Moving:

You can move around with the WASD keys or with the mouse: hold both buttons pressed and move mouse.(hold right click first then hold left click)
Pressing Num Lock will auto fly towards the direction your ship is pointing. Press Num Lock again to stop.
If at times you get stuck in a wall, hold Shift key then right click some free spot to move.
If map fails to load, try using the /reload command.

Communication:

Before you can type anything, you must press Enter every time you wish to do so, then again Enter to send the command.
There are several channels to communicate with others:
- shout channel, use /s text eg. /s Hi, i'm new here
- auction channel, /a text
- faction channel, /f text
- clan channel, /c text (only after you are invited in a clan or created your own one)
For private conversations, use /tell nickname text , also for quick reply to last message you received, use /r text
For a list of players online , use /who , for those you can group with , use /whogroup
If you want to see which players are connecting (maybe you are waiting for a friend) use /chan connect on

Fighting:

Now that you've learned a bit about the interface and exchanged some words with other people, it's time to fight
Check again the Cargo tab, see if you have weapons equipped and other systems. If you equipped a launcher too, be sure to equip the
missiles too (launchers and fighter bays require ammo to function). After the red timers on them finish, press Shift+P or type /powerall to power them up.
You are located now in the starting academy. To find the first enemies, navigate up while keeping an eye on the scanner for the red triangles (turn it on if you haven't yet).
All weapons and abilities have a certain range so choose your enemy, right click on it. If your weapons are not firing, try getting closer and/or hold right click bit longer
on the enemy. (You need to face target to shoot)
Weapons alone won't do much against enemies, so go to Actions tab, select a blue or pink action (left click once on it) then press a number from 1 to 8. That will assign the
action to the actions bar above the HUD. You will be able to use it in fight by pressing the corresponding number. If you are not sure what an action does, you can use
/ask action (eg. /ask fire bolt, /ask fortify etc). Now try an enemy again, see if it goes easier
Using actions (abilities) will increase your skills, so everytime you see one skill going to a round number ( eg. You improved in Pyrokinesis(3.0) ) check back the Actions tab to see
if you received any new ability. (them will appear top most of the list, scroll up to check)
Assessing mob difficulty:
There are different mobs around, some of them easier for you to kill, some harder or impossible. Most of them are level based, so if you press F1 (that will select self) you will see in
the info window your level, try not to go for mobs higher than 2-3 levels above yours. (You can see your level in the Info tab too, left side under your class)
Try selecting a mob with your mouse, left click on it. Mob info will appear in the info window, study it. You will see mob's power,crew,shields,hull and level.
Now, if you press the Alt key (or F10), a coloured ring will appear around the mob. That colour has some importance as follows:
- green - very easy to kill mob, yields no experience
- light green - easy , very little experience
- blue - moderate easy, little experience
- white - normal, decent experience (normal means you are in the right level range, there will be times when white mobs will kill you easily if your ship is not decently equipped so be careful)
- golden - moderate hard, good experience
- red - very hard, very good experience
The experience bar is divided in 1024 points, so mobs give you experience as follows: blue-35,white-50,golden-65,red-80. (eg. you need to kill 21 white mobs to earn a level, compared to only 13 red ones)

PS: need to tweak it, so any suggestions are welcome
