I am going to be telling you about Halo, it is a really good game. basicly its a firstman shooter where you are fighting aliens that call them self’s the COVANENT! there are different kinds of covanent, i’ll tell you from weakest to strongest. grunts are small and carry plasma pistols. buggers also carry plasma pistols but have wings. jackels have jackel like heads carry plasma pistols and have shields made of plasma. brutes carry either brute shots or spikers. hunters are big strong hard to kill aliens that  have there own weapon built in.
