EarthSiege 2 is a mech-simulator game published by Dynamix in 1995. It is the sequel to the 1994 game Metaltech: EarthSiege. It takes place on Earth approximately 400 years in the future when humanity has just freed Earth from the control of the Cybrids, a mechanical race created by humanity. The Cybrids return from their bases on the Moon and attempt to retake Earth.
The player controls a giant vehicle called a HERC (short for Humaniform-Emulation Roboticized Combat Unit with Leg-Articulated Navigation) which is essentially a walking tank. HERC's are equipped with various weapons, shields, and other advanced gear. The game consists of missions in which the player engages Cybrid HERCs in combat and eventually strikes back against them on the Moon.
