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.
Standard Weapon
The blaster may not be the strongest weapon or the best to hit with, but it will never run out of ammo and while indoors, it almost always hits something (sometimes that's something is you).
Scout armour
When in scout armour you can pilot all tanks and planes, therefore you should take the role of a pilot, take a blaster and spinfusor and a energy pack so if you get shot down you will be able to get back to the base for another plane or tank. Suggestion: Mine laying is also a good idea, as is sniper or stealth operative (ala the cloak pak.)
Assault Armour
Is the best, you can pilot almost everything and carry almost any weapon and you have medium speed. Suggestion:
Use the Blaster, Plasma rifle, Granade launcher and machine gun.
Juggernaught Armour
The turret armour, only use it if you plan to defend or have a buddy to trasport you, its best to be with two or more other units. Suggestion: Always have fusion mortar as it is one of the best weapons in the game.
Wildcat/Shrike Charge
This is a suicide move that isn't for the faint of heart. Equip yourself with scout armor and energy pack, plasma rilfe, chaingun, whiteout granades & mines then take a Shrike or wildcat depending on what you want and how good you are and the terrain. when you are really close to the base, make sure you have some turbo, aim beside the entrance and then charge as if satan was chasing you. Jump off before you hit the wall and the defense turrets sould go for the Wildcat/shrike. Grab the flag and when you hit the entrance again turn round and run backwards, lay the mines, and finally throw the granades, now use the jetpack to get back to the base.
Use the Mobile Base
Spawn the moblie base building and drive it to a key lockation. Example: If the flag is away from the base you place the mobile base as close to the flag as you can. If there is only a thin road or canyon that leads to the flag put the base here and make sure there is at least one unit that is at the base, with a repair pack as it is gonna take a lot of unisment.
Sniper Team
As a little dose of real life, snipers always work better in teams of 2's. This holds true in Tribes 2, as the scout is the only one that can use the sniper rifle but isn't that good in close quarters, it would be good to have someone to back him up. Example: One scout armour with energy pack, mines whiteout granade, laser rifle, blaster and spinfusor. And one assault armour with ammo pack, mines standard grenades, plasmagun, chaingun, blaster and missile launcher. Get to a
distant point so you can avoid cross-fire. Make sure you are well elavated, then lay all the mines you have in front of you. Now have the scout start sniping, and sometimes use the laser designator so the assault armour can use his missle launcher. If the enemy gets to close you should try to hold your ground, but after five or seven sniper kills you should change position so they dont find you.
