Some of you might remember Crackdown on the Xbox 360, and with a fully-upgraded driving skill you can actually drive straight up the side of a building. That was actually a glitch and not intentional, but Realtime Worlds left it in because it was a cool thing.
Which brings me onto my main point. In Resistance 2, you can hold down L1 to plant Bullseye traps, right? This was actually a glitch/undocumented feature in the first game, as evidenced by one of my video clips (link below) made before even the announcement of Resistance 2.
