AC Steel DragonEdit

AC Steel Dragon

AC Steel Dragon

Steel Dragon is a heavyweight two-legged AC equipped with a bazooka, the MOONLIGHT laser blade and a multi missile launcher double back weapon. Due to the Human PLUS enhancements of the pilot the unit can fire blade waves.


A slow, heavy juggernaut that possesses hard-hitting weapons, Tiamat is definitely not one to be messed with in combat. Human PLUS enables him to boost for prolonged periods of time without landing and thus he's able to fly a lot while hammering away at you.

A good strategy would be to make use of his limited mobility (as he's a heavy bipedal) and outmaneuver him. Also due to the fact that he's quite slow makes it very easy to land hits on him. One way of beating him involves fighting him in an enclosed map and outturning him and slashing him to death with a powerful laser blade like the MOONLIGHT. It is however, generally not advised to engage head-on with him in blade combat as he has the MOONLIGHT himself and can fire blade waves and this can take off a lot of damage so avoid this.
