There all over the campain, just get a sword
if you mean play as aliens you can in halo2,3 and halo reach
Yes. There are Arbiters, and other Covenant aliens!
Mostly for the blood, concept of aliens attempting to annihilate the entire human species and the occasional curse word.
Aliens.
I can't remember all the actual names of the aliens, but I can tell you the species if that's what you mean. There's the Ugnnoy's (Grunts,) Sengilli (Elites,) Kig-Yar (Jackal,) Mgalekgolo (Hunters) are all in Halo CE Xbox and PC. EPICGAMING king1. (Play my levels on happywheels.)
shoot aliens
In halo yes in real life no
Kill them
runnin around kill aliens
I think halo reach is DEFINITELY worth buying. After all, you are only hurting aliens. In this game different types of aliens are the enemies. It is a fun adventure game where it is only mature for violence. Basically you shoot aliens. If you think a game where you hurt aliens is fun, this is a game for you. If you don't like hurting aliens in a game, then maybe Halo Reach is simply not for you. Your choice.
it is about trying to save earth from the convent e.g aliens and there weapon is a halo which destroys planets
kill all the aliens
