A hulking tank of a unit, this beast is actually an alien from apparently some acid-world, in an environmental suit and with a plasma rifle. It far outstrips the Muton in terms of threat level for several reasons:
- High armor
- High HP
- Immunity to acid, fire, and poison
And lastly, after killing the rider inside, the suit itself will begin to attack independently with melee attacks, all while trailing the corrosive fluids of the former rider's homeworld all over the ground, obstructing your path. Fortunately, it loses it's armor pips and immunities, and counts as a robotic unit, so it can be hacked to be disabled or controlled: so take out the rider with the rest of your team, and stun or turn it with your Specialist.
