Halo Cheats
Different Ending:
Beat Halo's Campaign on Legendary to see a slightly longer ending movie.
Secret Cave:
There is in level 5 a secret cave at the botton of the map entrance. It comes
out on the side where they are not expecting a side attack from that side and
it shall be easier.
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.
Shotgun - use on big floods, and little floods.
When those little guys, that jump up at you, are all grouped together use the
shotgun, 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).
Use Assault rifle if the guy is standing still, if he or you are moving too
much it moves 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.
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.
Don't use your grenades all at once. They are to important, and sometimes rarest when you need them.
