If I could, I'd give a 15 for violence.
This is one of the best zombie survival games I have ever played! It's only downfall is, well, the fact that it ends at such an early stage. Maybe it should have a scoring system, also.
The violence in this game is great, and as the summary says, I'd give a 15 if I could.
Very, very good game, could be a lot longer, like Defend Your Castle, which has infinite stages.
I voted a four, but it deserved a 5, I wasn't thinking at the moment.
It's only flaw, at all in my opinion, is that it ends early on.
