+ this to keep the guid up:
Level 1: Jump off the edge of the building you're on.
Level 2: Walk forward until you get to that end of the train, if you turn right there will be a red lever, pull it. After you pull the lever turn arond, there will be a ladder, climb up it. Jump off the train.
Level 2.5: You'll wake up either on the tracks or beside them, if you're not already on the tracks go on them, you will hear the nice sound of impact from the nearby train.
Level 3: You'll be in a sawing/logging factory, ignore the saws they're not how you kill yourself. Press the red button to your left and the door will partly open. After that walk to the corner closest to the table. On the ground there will be a vent. Go through it and turn left at the fork. Press the lever and let the wall come down, then press it again and quickly jump on it. Congrats you get to hear the beautiful crunch of your bones and tase death err... victory.
