Quadra-Drone

A Twin with two really fast AI Drone spawners (stop spawning when you have four Drones) on the back (iblobtouch doesn't have AI Drones yet so pretend they are AI Drones). Upgrades from Double-Drone at Tier 4, which upgrades from the Twin at Tier 3. Can upgrade to Hexa-Drone (a Tier 5) at Level 60.
