I am surprised not more people are talking about this! Downloaded it a while ago and even though I cannot make heads or tails out of the dialogue, I completely dig the game!
Love shooting the heads off the robots and watching them attack anyone, it's also a good way to cause a slight distraction heh. The procedural damage caused is great stuff and makes destroying baddies a lot more statisfying and creates a few interesting situations!
Framerate seemed to slow down at times but not too massively, I heard the 360 version is better on this regards actually! But one of the most impressive things was the AI, loved how aggressively it is and all the neat little details that goes with it, I especially loved it when the robots were damaged extensively and how they would just ran at you to do a damaging melee attack.
Overall though, great demo, cannot wait to try it in English though!
