On the second level, in the beginning, when you first land on Halo, two banchys will fly around shooting you. To save some ammo, just shoot one banchy down and the other one will go away. (Banchys are Covenant machines that fly).
Battling Flood
Using a combination of assault, Shotgun, and grenades works best... Warning: Only use the [sticky] grenades at a far distance, especially for the little ones. Shot gun- use on big floods, and little floods. When those little guys, that jump up at you, are all grouped together use the shot gun, it shoots out a lot of bullets at a time (you can see this if you shoot at a smooth wall, or the ground...you can see all the marks it makes). Also close to medium range range to the big guys. Use Assault rifle if the guy is standing still, if he or you are moving too much it screws your aim very badly and you waste bullets and have to re load more often and then they have a clear shot. For the grenades use them when you know something is behind a wall, or when you see a lot of flood coming at you from a safe distance. for sticky grenades you MUST ALWAYS REMEMBER to use them at a safe distance because if you shoot it on one of those little guys that follow you you will get hurt bad too because of the blast that they brought with them, same with the big guys; I have learned this because the the Master Chief doesn't run to fast so he cant out run a lot of the flood. Don't use your grenades all at once..They are to important, and sometimes rarest when you need them.
Plasma Grenade
If your going to use a plasma grenade, try throwing the grenade on the alien where it sticks onto them. It will blow up on them making sure it will kill the alien. Also the aliens will do this to you if you don't move.
Hunters
Be careful of the Hunters! You need to hit them in the head or body to kill them. They are mostly armor.
Killing Hunters With Sniper Rifle
If you have a sniper rifle, you can kill the hunter by shooting the orange part on his back. It is the only part of the body not covered with armor. If not you can just shoot it with a rocket.
How To Save Ammo And Kill The Alien
Many of you gamers will discover that you can consome bullets very quickly in this game. If you walk up to an alien and push B, you will butt-end them with your gun. This works best ir you hit them in the back. On easy and normal it should kill them instantly but on higher it will take more then just a punch to the neck. Bigger guns work better.
