So if someone is interested how does it work on n1.
I installed it today and what I can say... hmmm... It's very unstable. On the beginning of this "demo" framerate is extremely goog however after few sec it's about 5fps. It's exactly when is first explosion. When I finally went into menu I had only some strange triangles. After many tries I finally started game but framerate was between 50-5 so pretty hard to play and I didn't have cross for aiming. I had triangle again. I can't wait until it will work better on n1.
