This is a good try but contains many grammatical errors, tips that don't make much sense, and things that you SHOULD do when it says not to and vice versa. For instance, throwing grenades up grav lifts is a good idea. Camping can be a good strategy. Driving vehicles is for ANYONE, not good players only. The teleporter thing doesn't make sense. You don't stay away from moving vehicles or they get a good shot at you. And in Halo, you use any type of weapon at any time. Work on the tips a little bit, they need more help than the players reading this. No offense, and these aren't too bad, but they're pretty rough.
