I just noticed a bug too.I don't exactly remember in which level it was, but there were many lasers and it was definitely before the catacombs. I think it was the level with the most lasers to that point.There was a horizontal laser. You couldn't just jump over it, because there was a "bit of a wall" (I don't know how to describe it exactly) hanging from the ceiling. I jumped in there by accident () and I got, just before my death, 600 points for an indirect kill. I know that I wasn't taking an enemy with me, so I must have triggered it. I tried a few times, and it worked for 3 times, then it wasn't reproducable anymore.I played with an XBOX360-Controller on a tower with Win7 Ultimate 64 Bit, my Graphics Card is an nVidia GeForce GTX 470. The game was normally launched using Steam and it only had normal privileges (Even though that definitely shouldn't be able to affect it). If you need any more information, no problem.But everything else works just fine! I didn't notice any single other bug. Congratz for such a bugfree, awesome game! Waaaay to uncommon in these days.
