Armored Core 3 once again puts you in the shoes of a Raven mercenary, with the task of piloting your own battle machine to use in a range of tasks (from destroying other mechs to seek and destroy missions).

After each mission, you are paid in full. The money raised can then go on towards the purchase of items for your mech. Weapon upgrades, better shields, even the opportunity to purchase what's called an Exceed Orbit, smaller robot gun emplacements that hover around your mech, giving you an added boost of fire power in the crunch. Four-player deathmatch modes are also included, where players pit souped-up mechs against each other to see who is the last robot standing.

The PSP release includes additional new parts and support for ad-hoc wireless play.
