A 3D, sim-like arcade helicopter-shooter tower defense. Repair, re-arm, and upgrade your helicopter at the FARP as the battle permits. Three flight physics modes provide a stepped learning curve and wider accessibility, and the tutorial mode provides a safe learning environment.

The National Laboratory has been studying all kinds of crazy biological "tools", and now it's under invasion. If any of that research gets captured, or worse, some sort of vector gets out, it could be the start of a happy new world. For zombies. For us, it would be quite inconvenient.

Perform aerial interdiction against the relentless Commies, using an increasingly sophisticated arsenal of weaponry from your Multi-Purpose Helicopter (MH), callsign Zombie 26. If zombies were to somehow result from your failure to fight off the invasion, and the zombies were to escape the city, all hope of containment would be lost, so fly like your life depends on it.
