Free games! Free games everywhere! The classic 2000 version of Aliens vs. Predator is now free for download on GOG.com and will be until a little past midnight on Friday specifically at 9:59AM GMT.
That's not a terrible way to get people to sign up for the GOG Galaxy beta test. An email with an activation code for the game will be sent a few days after you sign up.
This sci-fi first-person shooter has multiple single-player campaigns, Skirmish mode, and a fully-featured multiplayer mode that pits Aliens, Predators, and Marines against each other. The game will support the Xbox 360 controller and has been updated for modern systems.
