Got backup of Splinter cell a few weeks ago and started playing. I am able to use the night vision, but not the thermal. I didn't change controls or anything, and double checked the button (digital pad) to turn them on. I was able to use them in the police station demo (from OXM). Did I get a bad copy, beta, or any other ideas?
