Well I tried it out. Have to say I was fairly dissapointed.
I normally love RTS games and the unlimited units thing sounded quite appealing.
However the quality of the units and their textures really killed it for me, as did the non-intuitive control scheme.
I realise that the models look like stuff so you can have a whole bunch of them, but they are beyond acceptable.
Gotta say it is VERY like SupCom (same original designer right?) but less epic and more "made it in 5 minutes".
To its credit, it is free and the multiplayer system seemed well developed.
