nah, it says "Grab Character" in options when near em and then u grab em. Then you can intergote them, but in this level, only the guy by the morge will say anything. In the real game, you can force them to do stuff and stuff.
TheFrag's cool things to do:
1) Break as many lights as possible, get the alarm to sound and then run into darkness and turn on nightvision. From their throw cans at the bad guys anf laff at them. Then knock out
2)Do a split jump in the prison section by going up to one side of it, jumping off the wall, and double clicking jump at the top of your jump, hard to do at first but end up being really fun. DONT KILL THE GUARD YOU SEE RIGHT AWAY UNLESS YOU DO #1!!! Than, if you didnt do #1, shott at the ground and the guard will go wanderign around. When he directly under you, fall ontop of him and you will do asweet attack ninja style
If you did #1, go for the split jump right after the alarm sound and wait for the guard.
3)Its always fun to sneak around in that one offic eplace up the stairs (not the one with the 2 guys at the comps, but the one before that). Try hiding behind the blinds as long as possible and evading him from about 5 feet away, loads of fun.
Can't wait till christmas, I should be getting this for x-box
