Seeker

Seekers are aliens that are snipers. These warriors usually end up in Watch Towers to snipe out enemies, but when they're not they go out sniping in a certain spot maybe moving per shot. These NPCs have gas grenades instead which when an enemy is inside of it does loads of damage overtime. However, they only use their Grenades when they are not in Watch Towers because in towers they could gas themselves which none of the aliens want to happen at all. Seekers don't have the Last Stand Ability because they don't feel it is necessary by their very low health. These NPCs if you didn't notice have lower speed than usual, this is so they can have more precision when sniping. When this NPC is close to any enemy it will freak out, and instantly become frightened or try to run away from the opponent. Some of them may freak out and instantly snipe the enemy on sight when so close, but this rarely happens. The Seeker ranks up to a Officer which is a different type of NPC compared to the others you may have seen so far.
