Watch Gamespot give this (best arcade game yet) a low rating.

User Rating: 8.8 | Small Arms X360
Now as you know gamespot is known for being a little pickey when reviewing XBLA games. But I assure you this game is one of the best if not the best arcade games since GeoW: RE. The game is alot like Super smash bros. Melee. You have high flying mahem and guns galore. You will find at least 9 different characters with different guns and cool abilitys. Along with great gameplay the level you play on is almost as interesting as the person you choose. Some of the levels include:
*Scientific labs.
*Inside a tornado jumping on the objects inside.
*A floating chunck of land connected with another with a small bridge.
*Rock edges portruding from a waterfall.

Some of the characters include:
*A scientist who's head is fused with a flaming bag of dog poop.
*A chicken with a flamethrower and moltov cocktails.
*A pig wearing a "hitman" suit and who brandishes a sniper rifle and mines.

This game is crazy and also crazy fun.

Multiplayer is a blast. and the graphics are nice and prestine (better looking than any of the other arcade games on the 360.) This game could have been sold as an actual 360 game.

With loads of fun, lots of action, and a feeling of just plain hilarity, Small Arms is a must have with a price of about 10 bucks!
