Shattered Horizon Free Weekend
That's this coming weekend, the 4th-6th. There's a reason why I am pimping this one, however, which is that lots of people were interested by our recent examination of Shattered Horizon's maps and weapons updates, and this provides you an opportunity to actually try the astronautical zero-G fancy shootin' game out for free. It's also 50% off the normal price, which is precisely half as much as it normally costs. That, I insist, is science.
Might as well get an RPS contingent on there, eh?
