If i could live in any world I would live in the halo world. Halo is a game where you travel to different planets and kill aliens with all different types of guns that you find, you could even use the aliens guns. In halo 5 ( the halo game that i have) there are 2 groups of aliens one called the covenant, they are WIERD things and there are these little ones that you could kill in one shot to the head or you could charge on them. The other type of aliens is called the pertmeatheins. They are really wierd robot things that glow red and orange they have cool guns they shoot red bullets.
I would live there because it would be fun to kill aliens.
And that is why i would live in the world of halo.
