Once again, I thought I was all done with tower defense games but here we go again. First it was Orcs Must Die! that got me interested again (Hey, Robot Entertainment? Where’s the Vita version?) and now, the folks over at Sigma Team are making me want to dive in again with their offbeat take on the familiar genre. Granted, if you’re freaked out by clowns, blood, oddball game descriptions an/or indie games in general, just break out a deck of cards or something. On the other hand, heading to their website will hook you up with some free games from Sigma Team’s back catalog as well as allow you to check out demos of their other titles in the Alien Shooter and Zombie Shooter series. I’m a fan of both because they’re two non-stop isometric action games with light RPG elements and hundreds of enemies onscreen simultaneously.  It would be cool to see these guys get more respect for their work, but hey – that’s partially up to you, you know.
