MinMax Games has released Space Pirates and Zombies for Mac OS X. It costs US$4.99 (for a limited time) and is available at http://macte.ch/CyD7Z .
Here’s how the game is described: “At its core, Space Pirates and Zombies is an action based, skill oriented, top down space combat game. It’s similar to the ones we knew and loved in years past, but now using full physics simulation and modern graphics for those oh so pretty explosions. But as you dig deeper, SPAZ becomes much more. ”
In Space Pirates and Zombies, you fight zombie infestations across the stars. The game features 33 ships, 70 unique components, and a physics-based combat system.
