Record your own demos:
Go a map (preferably with bots), press ~ to display the console window and type /g_syncronousClients 1. Then, type /record <demo name>. A console window message stating "recording <demo name> to baseq3 demos" will appear. When done recording, you can stop the process by clicking on "Leave Arena". To play them back, go to the main menu and click on "Demos". Look for the name of your demo, click on it, and click "Play". You can do this process in both single player and multi-player modes.

Hint: Key binding for cheats:
You can have a cheat or command assigned to a key. Use any cheat listed above or any command for <cmd>. Use a key or button for <key/button>. You can do more than one command on one key.

bind <key/button> <cmd>
bind <key/button> <cmd> ; <cmd>

For example, bind F9 give all or bind F9 give all ; god

Note: This will overwrite any other command on that key. This will also save to the game.

Hint: Unlimited Quad Damage and other power-ups:
First, bind Quad Damage to a key. For example, /bind 1 give quad damage. Then, hold down that key until the symbol and the number disappear. After a long time they might return. Just hold the key down again. This trick also works for the Battle Suit, Regeneration, Invisibility, and Flight.

Hint: General strategy:
Always strafe in a circle around whoever you are shooting. Never stop moving. Always try to get rocket launcher first, then jump and zig-zag run to avoid getting shot. Always use the plasma gun when you have quad damage since it shoots fastest and can hold a lot of ammunition. Run backwards away from people and shoot them at same time.

Hint: Stop Xearo from getting the BFG10K:
To stop Xearo from getting the BFG10K, while he is on his way to get it shoot the target to squish him or have him fall into the wrong place.

Hint: Have opponents to lose points on the Appolips Void:
Go to the railgun platform. When someone comes on one of the two raising platforms, jump. Make sure someone is on the platform or you will lose 10 health, even if you land on them. They will get 9, 8, 7, 6, 5, 4, 3, 2, 1, 0, -1 to nine. You will get in the lead very far ahead.

Glitch: Human turret:
Get a grappling hook. Fire it at a wall. While still holding [Fire], change to a different gun. You will now be stuck to the wall. To exit, change back to the grappling hook.
