Halo 2
Unlock Levels
You can unlock the foundation MP map by finishing campaign mode on easy.
There are also two other maps to unlock: Marathon and Conclusion.
Try finishing harder campaign modes to unlock these levels.
Multiplayer Map - Foundation
Beat the single-player campaign on any difficulty.
Tactics
If you are in a closed area (small room, hall way, etc.),
then hold only 1 weapon, so you can throw grenades.
If you are in a open area (big room, outside, forest, etc.)
have 2 weapons in hand because grenades will be useless.
Be The Gunner
Get to a 'Hog and jump in the gunner/passenger seat and let the marines drive.
It will be x2 more effective than you driving (it depends on your skill).
