Another game from the well of innovation that is the SpringRTS community, Contact aims to be an Open-Source squad based RTS. It uses models from the DOTA-like attempt "Engines of War" which unfortunately never really got anywhere, other than a couple of nice mechs.
The Contact team released a beta on the 25 Dec last year, so it's not exactly breaking news, but the project is still moving forward and could use a couple of eyes if anyone is interested in it.
