Lots of Points:
It's more of a hint instead of a cheat but if you want to get alot of points in the game go and repair the enemy generator (but not all the way) and then blow it up and keep doing that, have fun

Easy Kills:
There are easy ways to kill people with a Spider Clamp Turret and there are good hiding places for them and I will tell you the hiding places for them on Tombstone.

. Behind your flag in the flag room so you can't see it.
.above the main doorway for your main base, and cameras in the hall for the doorway.
.And behind the brick supports for your main base.

It will be hard for them to find it.

Flag Defence:
Simply place a satchel near (or under) your flag and watch it from a safe distance (preferably out of enemy sites) and detonate the satchel when someone (on the other team -duh!!-) gets near it. The timing is kinda tricky, but it works. Really, it works.

999 Ammo:
Press ~ to display the debug menu, type $testcheats=1; Then, open the debug menu again and type giveall(); to get all weapons with 999 ammo

Brilliant Sniping Tip:
To be a really good sniper i.e. get loads of kills, use the humble blaster. Aim using the 'a' key ang then let loose a volley of about 15 shots on a steady target. I have used thins many times and it works really well.

Tips on Minotaur:
Beware, you must have good aim for this trick! To get a few good kills on level Minotaur, do the following: Turn into Juggarnaut (any type) with station pack, go up onto very top of base building and deploy it. Then change to energy pack and the following weapons:Laser Rifle,spinfusor,fusion mortar( the other 2 are up to you). Then go to an inventory station (not the deployed 1). When you are re-powered, go back to top of the base building, take out the laser rifle and look around for someone running on a mountain or flying around fighting etc. Good Luck!
