Halo: Combat Evolved - PC XBOX/Quick Strategies

From WikiCheats

Best strategies

Don't like those rocketeers? Well you're in luck, because this strategy can school anyone if you use it right. Pistol and sniper. They are the ultimate combo. See for yourself ;) Stick to frags, because plasmas are difficult to stick, and way to slow to activate. Attempt not to get into vehicles. You won't get ANY better by doing so.

ShotgunMelee

When in close combat range, shoot with you shotgun, and immediately melee after you shot your round. If you're close enough, it's an instant kill to your opponent.
