Cortex Command is an amazing pixel physics game from Data Realms. After going through a major physics overhaul, it's really starting to come together. This is gory multiplayer action where you maneuver rockets, robots and soldiers against your opponent. At the same time, you must protect your brain located in your base (hence the name) while buying and equipping troops to attack your enemy's base.
I recommend reading the instructions first. This version (build 13) features multiplayer skirmish and co-operative play with up to 4 friends in split-screen. Enjoy.
