The Alt Eisen is predominantly red with black coloring on its joints and white on various parts of its front chassis and rear verniers. This unit is very bulky for its size and heavily armored, and carries an extreme load of firepower, with a left arm-mounted three-barreled machine cannon, a stake-like weapon on its right arm, and a pair of shoulder-mounted projectile launchers. Unique to the Alt Eisen is a protruding red horn located on its forehead.
