The new OPM mag has a demo for SotC and it's really rad!
The demo DOES have a time limit (not sure how long, felt like 30 minutes) and if you stray too far from the starting temple it crashes, but there is plenty to explore and look at.
And one giant boss to fight! I can't talk about the boss fight because it would spoil it, but it's pretty cool.
There are some problems though. First is the camera. It's kinda weird.
Also there's pop-in, all sorts of slowdown and texture warping. But this is the may e3 demo so it's ok. I hope it's fixed.
the OPM mag gave the game a 4.5/5 and the cons were that the bosses were pretty much all there is to do in this game other than explore the world (and you'll only see a small part of it if you just go from boss to boss)
go give the demo a try. do it!
