Metal Arms: Glitch in the System takes place on the planet Iron Star, where an evil robot, General Corrosive, has taken control of the population and all that stands between him and total power is a small band of rebels.
The game's main character, Glitch, was found in a scrap pile by these rebels and reactivated. His design is different from all others and he has no memory of his past. There is even talk that he might be connected to the Morbots (the race of people who created the bots of Iron Star). Colonel Alloy has taken you into his rag-tag militia in hopes that you will help take down the evil general and his Mil bot army.
You start off with a simple mining laser. This is a good backup weapon when everything else fails, but be warned, if you use it too much it will heat up and shut down. You will pick up many other weapons along the way, each with its own drawbacks and benefits. For example, one weapon is called the S.P.E.W - basically it's a chain gun, it has rapid fire, but uses ammo quickly. Other weapons include the Rivet Gun, the Slingshot, the Scatter Blaster, the Cleaner, the Toaster and several more. Also, several of these weapons can be upgraded when Glitch runs across a EUK (Equipment Upgrade Kit).
Glitch will also be able to use various vehicles that he finds in Droid City; these vehicles will help him get to new locations fast and allow him to mow down baddies efficiently. He will also pick up Arm Servo Upgrades that will allow him to reload faster, as well as other changes that make a big difference when in fights.
Another interesting piece of equipment is the Control Tether. This device allows Glitch to hack into other (enemy) bots and control their actions. Not all enemies have the necessary port to allow Glitch access though, so you will need to plan your tactics carefully in order to use your enemies to your advantage. This becomes necessary several times and adds a new aspect to the game.
There is even a multiplayer aspect where you and a friend can go head-to-head in several games. But you have to earn these games. In the single player mode, you will run across yellow chips - these unlock multiplayer games for you to try out. Other games are unlocked by completing a mission in a certain amount of time.
