Fortified for free on Steam

Seems to be a 50s themed action/tower defense game. Free until the 8th. I downloaded it but haven't had a chance to try it out.

Checked it out and it looks like a bare-minimum non-fantasy Dungeon Defenders.

If anyone is looking for a game of this type, but far better, just get Dungeon Defenders.
