I don't find the game that hard to learn. WASD to walk around, hold alt while moving to run faster, space jumps, control/left click fires, shift/right cli9ck to reload, number row/scroll wheel to go through weapons, left/right arrows (or move mouse left and right) to turn by more percise incriments, or q and e to turn 90 degrees like 0-90-180, etc. h checks health, c checks clips (remember one clip is the clip in your gun), x to check bullets in the clip, j to dive left, l to dive right, tab to check who's online. There is all the keys, and here is the dammage values that I can remember.
1. mk14, starting weapon: 50 ammo per round, 5.5 fire rate, 7 damage per bullet, moderate range. A standard starting gun with high clip size and low damage.
2. m60. 60 ammo per clip, around 15 damage per bullet, 10 fire rate. Faster gun, but at a price of accuracy, good for people who just spawned if you get lucky.
3. sauce90. 5 rounds per clip, 20 dammage per bullet, 3.5 fire rate. high dammage, long rangte shotgun like weapon. Great for short range ingagements, but is not accurate at high ranges.
4. mg4. 15 ammo per clip, 12 fire rate. 15 deamage per bullet. 2nd fastest firing gun in the game. Good to use, against anyone.
5. fists. 20 damage per hit, requires holding ctrl/left_click to hit. Fast kill if you run out of ammo and they are iun close range, and low health.
6. doom90. 100 ammo per clip, variable fire rate, 35 damage per bullet, requires quick control spam ot work effectively. The most over powered weapon in the game. With a variable fire rate and a rather straight shot, the only down side is your aim, and gun sway. The damage is greatly reduced depending on the angle. I personally don't use it because of its unreliability.
7. knife. unlimited ammo, requires holding ctrl/left_lick to hit like the fists, 20-35 damage per hit, shorter range and slower. Like the fists, good if you have no ammo but the fists are better in my opinion.
8. mp5. 25 ammo per clip, 8 fire rate, 25 damage per bullet, a lot of sway to this gun. If you hit your shots its deadly, good for garding things like doors or items. You only get 2 extra clips though, and it burns through ammo quickly, so you hav to be careful.
9. shotgun. 2 ammo per shot, 2 fire rate, reload time of almost instant, like a pump action would be, 30 dammage per shot but very unpersistant in that area, shortest range actual gun in the game. Its just, bad, ok?
10. m16. 100 round clip, upgraded to 150 for any clip after the first clip, 19 dammage per bullet, rfire rate of about 7 bullets per second, very accurate, but if spammed for too long the gun sway system kicks into overdrive. This is my favorite gun in the game, its my old trusty if I don't have an mp5 or ak47.
11. mj420. 40 ammo per clip, 20 damage poer bullet, 10 bullets per seconds, mid range gun with decent accuracy, but not high accuracy. Spammy gun, with high damage and good potential for people with bad aim.
12. ak47. 67 bullets per clip, 25 dammage per bullet, high fire rate, like 11 per second or so, low accuracy after just a few bullets, but high damage for the bullets you hit. My favorite of all time, the most over powered gun in the game, hard to dodge bcause of its high fire rate and clip size, but its also loud and easy to sneak behind for some quick hits.
That's all I can give you right noww, let me if you need anything else.
