To tell you the truth I like the sprites and the fact they're somewhat balanced. I have to agree with Grif on this one though.

Honestly, all I see here is Tosty's turrets he made for the Rigger pack a while back. At least those ones explode pretty violently when you use the jetpack which makes them that much more functional.

Good sprites, overdone concept. Maybe if it had a faction to go with it.

I wish the turrets would just die when they lost their weapons, but yeah, it's not unbalanced. Though I did take control of the heavy one and shoot down a hell of a lot of landing craft before getting clipped by shrapnel and being disarmed.
