Multiplayer BattleTech: 3025 is a PC MMORPG developed by Kesmai during the same period as Microsoft's MechWarrior 4: Vengeance.

The game occupies the fictional 31st century universe of BattleTech and focuses centrally on the large robotic war machines called BattleMechs ('Mechs) and the individuals who pilot them.

During this period Kesmai focused on reengineering the 3D combat portion of the game to use the studio's internal K3D rendering engine.

Development continued after Kesmai's purchase by Electronic Arts and included an overhaul of the galactic conquest portion of the game.

The results of such battles were planets being won and lost for the five major houses, shifting the borders of various factions in the Inner Sphere.
