Atlas is one of the most powerful Mechs in the BattleTech Universe, a fact that allows it to boast the class of Assault. Designed by House Steiner, the Atlas is a devastating BattleMech. In the Mechassault series, the Atlas is armed with four pulse lasers, four autocannons and four LRM launchers.

In MechCommander 2, the final boss and leader of Steiner uses a heavily modified Atlas, with most weapons and armour removed and fitted with jump jets.
