Don't die and go slow. Use plasma weapons.
its easy, folow cortanas directions and shoot what ever is not human.
?? You play until one team gets 100 kills. However, I'm referring to Halo 3 online, if your meaning Halo: Combat Evolved, I suspect it's the same.
I have played and beat them both on all difficulties, both are challenging, however Halo Combat Evolved Anniversary is more challenging so that makes H.C.E.A. better than H.R.
u beat all the levels!!!!!! ----------------------------------------------------------- Dude stop saying crap like that. Yeah, you beat the levels, but i heard there was some secret way to unlock EVERY SINGLE bonus feature and nick-nack in Halo 3- but i hear you have to have Halo:Combat Evolved and Halo 2 for comp beaten and then connect your 360 to your T.V. and you do the code.
The Flood of Halo: Combat Evolved is fairly simple to kill. Shotguns and other human weapons are very effective. Infection forms (the lil balloon things) are easy to kill and will die even if steped on. If there is a group in one spot, one shot will kill them all. Flood combat forms can be killed easily with the shotgun, assault rifle and the pistol. Flood carrier forms can be killed with 1 shot from the pistol, because the explode when shot, make sure they are not near you when you kill them.
you can press the start button on your controller, go down to end game, and start on the next part or a new part from the campaign. other than that there is no button solution combination, no secret code, or anything like that.
