Fun and cool! But...
The only real gripe I have is how often you are reminded to spend real money on this game. It is technically a free game, but more often then not, if you spend real cash on this game, you'll advance thru the story faster, easier, and more directy-rather than getting stuck at specific points and forced to wade around the area for an annoyingly long period time in order to figure out and then execute your way around these "cash-grab" traps.

Other than that, this is a solid FPS, with awesome graphics. They do a really good job throwing you into this era's mob world. The gameplay is intuitive, and the music adds to the experience.

If you're not bothered by constantly being asked for money, then this will be a fun game for FPS players, hardcore vs casual players alike.
