If you haven't heard the news yet, and are interested in Sigma, you'll be pleased to know that a new demo, featuring a whole new exclusive level(that won't even be included in the finished game)is coming to the PSN in 4/27!
I've played all the demos available on the European PSN and I was pretty satisfied, not blown away, yet satisfied. I'm getting pretty excited about this demo! :D I'm planning on buying Sigma and well the demo could a) fully convince me to immediately run out and purchase Sigma when it comes out or b) make me scream like a girl in frustration on what I should buy for the money I've saved...I'm kidding(or am I?)...But seriously though I'd be left with no backup plan, since there isn't anything coming out in June that I'm remotely interested in(besides Sigma of course).
