A fun but short game, good for a rent or bargain bin.
It's also rather fun to shoot the old time guns, they did a nice job speeding up reload times so it's not a drain on the fighting but still reminds you of when your fighting. My favorite weapon by far was the grenades, easy to use, kills lots of enemies and well it's just plain fun to watch your enemies get blown all over the place.
The game is pretty short and even shorter when you know what to do, all in all it probably takes 2 to 3 hours to beat a single playthrough and maybe 5 to get all the achievements. Speaking of which are very easy to obtain all 1k points.
Graphics leave a bit to be desired and look like early Xbox360 games. Guns sound good and powerful. AI say the same things during combat over and over again for what I can tell both sides which can get to be annoying.
Overall a fun experience if it can be gotten at a cheap price.
