vehicles and waiting, too key things that i do in halo, you either wait for an enemy or wait for a good weapon or vehicle, or..... you know, if you wanna just have action and no wait- keep moving, CONSTANTLY look behind you or on your radar in the bottom left, you can get little exp from forge and custom games, even if you kill A S**T LOADA PEOPLE you still will get 5 exp, but you can still train in the campaign....so your ready now
