Halo Zero is just plain fun. And plus its free. I downloaded it not that long ago but I have already beat it on normal. But other than it being easy this game is amazing! It has a pretty good varity of weapons and a good amount of enemies. It is very good and also it has online multiplayer which isn't that bad. So overall this is a fun game and is a good 2D Halo video game. So if you have a computer and you are bored just go download this game... it's free. I really like this game and I know that you will too.
