Unstoppable Gorg on Steam is on sale for today only! Normally $9.99, it is now 50% marking it down to only $4.99. Have had our eye on this game since it's release, but held off buying due to it being yet another tower defense game. Have to admit though, it has a ton of personality and looks to differentiate itself by using the rings and giving you the ability to move the rings to reposition towers. Hit the jump to tell us in the comments why we should be playing Unstoppable Gorg!
