Very Epic
I very much enjoyed the story that was being told, but I didn't really see what that had to do with the gameplay. It doesn't matter though.
The game was pretty cool. There was a lot of options for strategy, but very little time during the game to implement. switching between bunkers got confusing and you had to be really fast in order to survive. I ended up sticking with the pellet guns through the whole thing because the fast pace demanded an insane reaction time with the other weapons and defenses. The scoring system kept it from getting boring; I love seeing money rack up all rapid fire style.
It looked cool (nukes were badass and music added epicness), played kinda alright, and had a pretty good story. Just slow the pace down next time and make the other weapons a little bit better. They all seemed like rip-offs compared to the ultra cheap and reliable pellets.
