The Insurgency Website now offers what they are calling "early access" to this indie team-based first-person shooter, as players can choose to pre-purchase the game for "pre-beta" access, as well a entrance into the beta test, and a copy of the full game when it is complete. Here's word on the game and why it may seem familiar:

INSURGENCY is a first-person team-based shooter for up to 32-plus players designed for Windows® PC and Mac OS X (and in the future, Linux), using Valve’s Source Engine and distributed through the Steam platform. If the name INSURGENCY sounds familiar, that’s because it is based on the popular total conversion for Half-Life 2 -- Insurgency: Modern Infantry Combat -- that saw more than a million free downloads and was awarded the ModDB “Player’s Choice Mod of the Year” in 2007.
