[quote name='nnthomas']Is the second one any better?[/QUOTE]
Personally, I liked the first one more, though the second is fun too. It seemed like the sequel just repeats a lot of the same ideas as the first one, y'know? And the addition of human enemies just didn't work for me: I can shoot people anywhere; I'm here to blast freakazoid monsters.
But for 10 bucks, I'd say it's worth it if you liked the first one.
Thanks for heads-up, OP.
