Armored Core [Agetec RE-RELEASE] (Sony PlayStation, 2000)

You play the role of a Raven mercenary, piloting a powerful Mech called "Armored Core". You only work for profit, as the money you make goes towards upgrades and repairs to your mech.

Multi-national companies are lined up at your door, paying you to complete certain objectives, which mainly include the destruction of a certain target or another mech. The more you complete, the better the pay and job offers, therefore allowing you to build the ultimate Armored Core.

Apart from the single player campaign, you can take on a friend in a multiplayer battle. You each control a mech, and battle it out in a large war area (ranging from huge cities to desert plains).
