Mech-on-mech arena combat comes to PSP with Steambot Chronicles Battle Tournament. Your ultimate goal is to win Orion City's Trotmobile tournament, but first you'll need to earn some cash and fame by completing various quests on behalf of the local populace. Whether it's making a delivery run across town or working in a mine, finishing each job will allow you the funds to customize your bipedal Trotmobile in the areas of arms, legs, windshields, grilles, bodies, and more. Then you'll be ready to take on some heated competition inside a coliseum. Up to four can participate in Ad-hoc multiplayer battles with either their custom-built Trotmobiles or with a standard mech. The latter option supports game sharing with only one UMD. ~ Scott Alan Marriott, All Game Guide
