Metal Arms: Glitch in the System (2003)

Genre: 3rd Person Shooter | Players: 1 -4 | Developer: Swingin Ape Studios

A somewhat overlooked gem of an action title by a rookie developer before they were bought up by Blizzard.
Gameplay:
Players control the droid Glitch in a third person perspective to battle numerous hostile robots with a wide variety of weapons ranging from machine guns and flamethrowers to missile launchers and some more unique options like a gun that shoots entire sawblades and one that allows control of enemies to do the fighting. All of these are also upgradeable to add new features and firepower. There are also different grenades and vehicles to take advantage of. Another cool feature is limb-specific damage. Tough enemies can be neutralized by destroying their weapon arms or hampering mobility by destroying their legs. Multiplayer has all the standard modes with some new ones that take advantage of the enemy control. Before online was ubiquitous there was 4 player split screen which is what you get here.
Controls:
Standard shooter fare as one stick controls movement and the other controls the camera. If it ain't broke, don't fix it.
Graphics:
Cool industrial aesthetic with a few minor hiccups, but nothing gamebreaking.
Sound:
Great soundtrack with a mix of metal and electronic. Voice acting is top notch with special consideration for Dan Castellaneta as Krunk, the foul-mouthed repair droid.
Story:
On the planet of Iron Star, miner droids have been enslaved by a race of military droids led by the giant General Corrosive. The miners start a rebellion led by Colonel Alloy and when they find Glitch in pieces, they repair him and put him in the fight.
Buyer's Guide:
Easily found and cheap too. Can be had on Xbox, PS2, and GameCube for between $5 and $20. Also can be found on Xbox 360 as part of Xbox Originals for 1200 Microsoft Points ($15).
