Honestly, I don't really like it. At all. Sprite comics rarely ever catch my interest, aside from one notable exception. The fact that by all appearances you just put it together in MS Paint without any real effort to make backgrounds or anything else further reduces the appeal.

And this may be somewhat my fault since I don't play Halo, but I didn't find it funny. At all. And the Red vs. Blue thing at the end just made it feel even worse, it's as if you can't make your own jokes and are thus stealing the jokes of others.

Anyway, I don't want to dig too deep here but you get the idea.
