A free weekend is underway on Steam for Disintegration, providing the chance to sample this recently released Windows first-person shooter with RTS elements (thanks SteamDB via Ant). Word is: "Play Disintegration for free from July 30th to August 3rd! Join its exciting multiplayer across three different modes and discover this unique aerial tactical shooter with real time strategy elements." Here's a bit on the game:

From V1 Interactive, the new 30-person independent development studio founded by Marcus Lehto, the co-creator of Halo, comes Disintegration, a sci-fi first-person shooter combining FPS and real time strategy elements. Set in the near future on Earth, the only hope for human survival is through Integration, a process developed to preserve human brains in robotic armatures. You play as Romer Shoal, a former Gravcycle pilot in command of a small resistance force still grasping onto the fading memories of their human selves. With the domineering Rayonne forces set on eliminating the final remnants of human society, it’s up to Romer and his crew of Outlaws to fight back and reboot humanity. Pilot a variety of weaponized Gravcycles and command your crew on the ground by leveraging a variety of unique unit abilities and mastery of your own personal arsenal to dominate the battle.

In addition to the thrilling single-player campaign, Disintegration features frenetic PvP multiplayer where pilots and their crews compete in three exciting game modes across a variety of maps.
