Brisbane-based developer Voltic Games has released Nightmerica, a retro-styled, side-scrolling action game for iOS devices.

Described as the "insane baby" spawned by the unholy union of Super Crate Box and Borderlands, Nightmerica equips players with randomly dropped weaponry in a battle against endless waves of enemy critters. The game offers three different arena backdrops, and includes Game Center leaderboards and achievements, so you can test your survival skills among friends.

Nightmerica is priced at 99 cents.
