A Homerun
This is a very well-done expansion, despite being run off the same game engine as the first. The new character is a nice addition (and VERY nice to look at), and the new items and weapons are a nice touch as well.
I only have one gripe, and I hope it's solved for the upcoming sequel. The Berzerker Coins only give you $10. Will there be other color-coded coins that award higher bonus money, like $30 or $50? It'd be nice to see some variety with that.
That said, this is a welcome treat while I wait for the sequel. Rock on!
