Effect: Beat Steve in tutorial faster
When:
When you come up against Steve in tutorial mode
How:
Go to tutorial and go through most of it until you get the C4 explosives. Pick up both of them (They should be right beside each other) and use ONE to blow up the boxes. Save the other for Steve. When you get to Steve run to the middle of the room (about where Steve runs). Put down the C4 run back to the box a little behind you put your back to it and duck. Fix the camera angle so you can see the C4. Now wait for Steve to run. He will run and stop to pick up your C4. When he tries to pick it up, blow him up. Instant kill. (don't worry you won't be in the way of the balst)
