Kill Final Boss easily:
First when you enter the boss room strafe one step to the right
so you see the tank commando and shoot him down with your rocket
launcher when he's dead run forward to the flying enemy and run from
right to left and shoot at him with your hyperblaster and when you
dont have any more ammo take the minigun and do the same thing again.
Then you shoot the other tank commander with your rocket launcher and
when do the same thing to the flying enemy
Hidden multiplayer areas:
In the Hydophobia level, go into that hallway thats all red. Stop
in the center and you'll notice a darkened area on the wall. Shoot it
and it will reveal a BFG10K. There's another secret. In the pool of
water by the super-shotgun, jump in and shoot the center of the wall
by the shotgun to reveal a quad damage.
In Toxic Vats level,go into the narrow hallway with a ladder on
each side. Take the ladder that brings you to the platform where you
can get on the moving crane thingy. Take the hallway to the part where
you're standing on the glass platform with the hyperblaster on it.
look down through the glass and you'll be able to see a railgun
submerged in a small section of the toxic waste. Jump in and swim down
and get the railgun.
Take the chaingun, which is weapon number 5 in the list, and then
press the fire button. Keep holding it down, and then change your
weapon to anything else. Now you should have unlimited ammo on your
chaingun AND machine gun if you did it correctly. This may take a few
If you want to save a game whenever you want, just walk back at
the beginning of the level, there you can save.
If you need more bullets for machinegun or vulcan (you know the
big rotating one) take the vulcan. Then shoot and hold it, during that
choose another weapon. Now you should have unlimited ammo for those
two guns. The same you can do with the hyperblaster in multiplayer
level toxic vats (you must finish the game on medium first)
Walk on the place where you can find the hyperblaster, then shoot
till you have 37 bullets left. Then switch to machine gun, do the same
trick as above, now you should have unlimited ammo for the best weapon
in the whole game.
If you really want to beat your friends on multiplayer, first
enable one hit kill. After that begin the game, run like mad to get
the hyperblaster to defend yourself for a couple of minutes. Then go
after the BZG when you have it, simply aim at the ground and jump (set
gravity on zero, or else you are toast), try to control and then you
have to shoot but you must blast of when you are in the top of your
jump. If you shoot then you are able to fly for about one minute. You
can navigate yourself while flying to look up and down, walk forward
an backwards. If you are very good at it, you can even make a salto.
Imagine yourself what happens when you make a looping 360 degrees and
shoot at the same time with a hyperblaster.
Before you walk into a corridor or a small section always check
the walls. There are over a hundred secret rooms in the 1st three
If you walk on the 6th level (maybe 7th) then you will see a big
hole under you lava in it. You can walk over it by enable a button
which will make a bridge, first you must do that. Then do something
unexpected: Throw yourself into the lava! You can swim in it. Be
carefull! You only have 15 seconds, before you burn out. You will find
an BZG weapon, the green beam cannon blaster from multiplayer! This
weapon is very handy against the tanks and ecpecially the tank
