UPDATE - Release: Overload, free sample now available

Zero-G explosions.
Overload is now available, DRM-free on GOG.com
Spin, dive, shoot, blow stuff up - you got six degrees of freedom and you will need every single one of them if you're to destroy your mechanical enemies and rescue your people before disaster hits. Descent into an epic single-player campaign with upgradeable ships and challenge levels, then go online for more bombastic action and ship customization.
UPDATE: Be sure to check out the demo for a nice slice of the action, before you make up your mind.
