Alpha Spitter

Life
It has 15/16 Lifepoints.

Behavior
Aggressive Creature. Attacks the player on sight with a big, exploding fireball that quickly splits into more, smaller fireballs.

Strategy
Get a rebar gun and quite a few healing items. Close combat is suicide. Try not to get hit with too many fireballs at once - they'll deplete an engineers life nearly completely within one volley. Try to find some cover (or build some beforehand or use the tractor) - shoot whenever possible and duck behind cover to heal.

Another approach is to use Xeno-Basher and spam melee attacks.

Loot
Drops an Alien Organs.

Variations
Two known variations exist:


 * Red: This is the most common variant and fires red homing shots.
 * Green: This is a much lesser known variation that resides farther away from the starting location. It usually guards an artifact or precious resource, and its attack pattern is different. It stays at long range and attacks in a pattern similar to the smaller spitters, but has two shot modes.  The main attack is a single extremely fast projectile that is difficult to dodge unless you are at extreme range.  The other attack happens less often and shoots a volley of about 8-12 balls at you in a tight cone shape in rapid succession.  Unless using cover, fights happen at extreme range and require anticipation and arcing shots with your rebar gun.
