Arguably one of the toughest ground units that one can encounter in the Xcom series of games, converted to be used in your Starfinder game!

The Andromedon is an alien that has been permanently melded into what is essentially a suit of powered armor. It contains all the nutrients required to keep the alien ‘pilot’ alive. This makes the creature exceedingly tough and hearty, able to not only withstand a great deal of punishment, but dish it out.

Up close, the suit can deliver a powerful punch attack, or it can simply choose to run straight through enemy combatants, inflicting heavy damage. It also comes with heavy plasma cannon, which it can use with pinpoint accuracy.

Typically once the alien pilot is killed, one would think that this would be the end of the creature. That is not the case. The suit, upon sensing the death of its rider, takes control and will continue to fight, albeit at a lesser effectiveness. It can still attempt to trample, and it can punch, but that is the extent of its combative effectiveness. The only real advantage it possesses is that it leaves a trail of the nutrient and coolant solution that was used to keep the pilot alive, and this is toxic to any organic creature that it comes in contact with.

Special Abilities

Acid Bomb (Ex): Once per day, as a standard action, the Andromedon can fire a globe of highly caustic acid at any target within 100 feet (line of sight). The acid bomb has a burst radius of 20 feet and anything caught in the area of effect must make a Ref save (DC 19) or suffer 5d10 points of acid damage, a successful reduces the damage by half. To make matters worse, the acid will remain in the 20 foot area for 2d4 rounds, and anyone moving through the area will automatically suffer the damage (save for half). If someone even with the evasion ability consciously moves through the area, they do not gain the benefit of the evasion.

Coolant Trail (Ex): When the Andromedon is destroyed, every time it moves it leaves a trail of toxic coolant behind it. This trial is 10 ft. wide and will remain in effect for 3 rounds. Anyone moving through the trail will automatically suffer 3d10 points of acid damage unless a Ref save (DC 19) succeeds. Note that if the suit tramples, any target it attempted to run over is automatically subjected to this effect.

Mechanical resurrection (Su): When the Andromedon is reduced to zero hit points, the alien dies, but the suit automatically takes control and can move on its own on its next round. The suit has only 100 hit points, and it can only make a punch attack, at a -4 to hit. Furthermore, both EAC and KAC are reduced by 4 each, and it is considered to be mindless. Lastly its initiative drops to +0, although It still retains its normal DR and immunities. However, the suit does leak the special cooling and nutrient fluids that the alien needed to survive, and as such it leaves a coolant trail behind it wherever it moves.

Trample (Ex): As a full-round action, the Andromedon can move up to twice its speed and literally run over any opponents at least one size category smaller than itself. The creature merely has to move over the opponents in its path. The Andromedon does not need to make an attack roll; each creature whose space it moves through takes damage. A target of a trample can make a REF save (DC 19) for half damage. If it attempts the save, it can’t make an attack of opportunity against the trampling Andromedon due to the creature’s movement. The creature can deal trample damage to a given target only once per round.
