Perhaps the game does make a difference between standard obstacles and special ones (like the Security Sensor in the video), though. But to slide, I had to use the crouch-button. And if I wanted to climb onto something which was neither requiring me to jump off an edge or walk against a wall, SMART wouldn't automaticly make me jump onto something.

watch the "dawn of smart" vid and you'll hear that seperate items have actions bound to them, sliding under, crawling over. what can be wallhopped on, what can't be. humans are still involved as they still have to bind the actions to the items, and that's the reason why destructible environment won't work yet
