Ok, i have some bad bug here that wown't let me move up the campain...it's in the VATTLAND mission...fps mode just after i get the laser rifle and when i try to go down on the second staircase (after killing 2 robots) it just crashes. I tried to run in window mode, decrease rezolution, quality...nothing seems to work. I use windows 7 64 bit, core i5 ivybridge with 8 gb ram and radeon 7950. Game version is 1.6.0011. Any ideeas to workaround this ? Thank you.
