Shock Rifle
Right click, then left click to cause a rather big explosion that can do some good damage.
Aiming
With bigger weapons, such as the rocket launcher or flak cannon, aim at the feet to get a better shot.
Escape from lava or falls
If you have the "god" code enabled and you fall into lava or off a cliff, you do not have to disable the code and die. Instead, enable the "fly" code and fly back up to land. Then, turn it off by enabling the "walk" code.
Invisibility
Get killed or blow yourself up. When you see the stats, enable the "loaded", "allammo", and "walk" codes. You will be totally invisible, with no lines or anything else. However, you cannot pick anything up.
Deathmatch champion
In any deathmatch level, once the game starts and you can fly around to view the level, enable the "god" code. Exit cheat mode and press the fire button to start the match. Once the match is started, enable the "summon warheadlauncher", "allammo", and "fly" codes. Exit cheat mode. If the Redeemer is not already out, press "0" and enjoy. You will not get hurt if you get shot by someone, or if you go in the explosion from your Redeemer. Note: this will work in CTF, Domination, and Assault. Note: If you enable the "fly" code before you press the fire button to start the match, you will not be allowed to do so.
In deathmatch, when you enter a match and you get the "Press Fire to Start" message, fly around the level and look for a place that only you can get to, and only with the "god" or "fly" code enabled. When the match starts, enable the "god or fly" code , return to the spot you chose, and enable the "summon warheadlaunche"" code. Leave the Redeemer. If the level already has one, place another in your chosen location anyway, as sooner or later the CPU players are bound to grab the Redeemer provided by the level. Then, disable the "god or fly" code and start shooting. If you start losing badly, or someone else is closer to winning than you are, grab your hidden Redeemer (and, if desired, enable the "allammo" code) and fire away.
Fun with flight
Wait until you die and enable the "fly" code to come back on the battlefield. Then, enable the "walk" code to walk normally. Nobody will be able to see you. Note: To come back as a warrior, you must be killed or commit suicide again; however it will not count as another kill or suicide. Also, when a match is finished with a view of your player, enable the "fly" code and watch him swim around the battlefield. You can still shoot, but it does not seem to do anything.
Interesting killing methods
All of the following use the "playersonly" code in order to freeze the game. Since you cannot change weapons while the code is enabled you have to pre-select it. Most of these tricks also have a certain amount of "backlash" so the "god" code is also recommended. Some of these tricks require a lot of ammunition, so the "allammo" code should also be used. Once you are finished setting up the kill, move the console out of the way so you can see what happens then deactivate the "playersonly" code.
Sniper Rifle: Find someone to shoot, line up a head shot and fire. The target's head will become suspended in mid-air with a cloud of blood underneath and the body will fall to the ground. Note: Try to avoid zooming in as the game will occasionally freeze in the zoomed mode until you deactivate the code.
Rocket Launcher: When you use either primary or secondary fire, the gun will automatically load up six missiles and fire them. However, the rockets will stay where you fired them, resulting in them staying grouped. This allows you to run up to an opponent and surround them with groups of missiles.
Ripper: Hold [Fire] and run around randomly in an opponent's general area until he/she/it is surrounded by as many Razors as desired (usually about 50-60). Re-enter the code and clear the area as the Razors ricochet about and cut your opponent to ribbons.
Ripper: As above, only more tidy and less random. Face the direction your opponent is running. Aim the Ripper at the target's feet and hold [Primary Fire]. Begin to move the mouse very slowly up in a straight line, creating a "stacking" effect.
Redeemer: Enable the "allammo" code to get 999 missiles. Freeze time, then enable the "fly" code. Start flying around the level with [Primary Fire] held before reactivating time stop and consider the scale of the virtual pain your about to cause. Then start time and watch the fireworks. Note: Inspect a missile to find something interesting written on it. If you use this trick on a relatively large scale the game will slow down a lot, even on the fastest computers.
