Next map in the series of mind fuck maps. This one is pretty much a "Monster jumps out of a closet" style trick.
Basically, you walk up to the door, the light fucks up, and wham, out comes a citizen running for his life, followed by a manhack which saws the shit out of him and then comes after you. It all happens within 2 seconds, keeping the player alert, and if we're lucky he might even jump a bit.
To time the scene I've used a trigger_push with the manhack to make it fly really fast. This also increases the scare-factor a bit. The faster the better. It will first fly through the citizen, and then directly at the player. Notice that if the player wears a suit the trigger should be further from the door as if the player sprints he might be able to get close enough to the scene to make it.. weird. It would probably not ruin the setup, but getting too close ruins most scenes.
This was initially a map for tunamoo, who needed an example on how to make a citizen get killed by a manhack while running out from a door, I just put some moocowyness into it, and I think it turned out ok. Enjoy!
