A fire casting skeleton that suddenly paths towards via a scripted trigger is kind of instant death, followed by instant death, which would kind of bugger up the whole aspects of a stealth game, as you wouldn't know the path of the undead. You're more likely to scare someone to death by rattling a chain close behind them via a sound file than anything visual, fear is generated by something you can't see, unseen horror is more scarier than seen horror. eg like in horror films, you dont usually see whats killing the cast off until right at the end. Plus in doom 3, lights are dynamic the fire from the fireball would light up the room and the thief which would still result in instant death, and its soul distroying to reload instant death events when you cant figure out how to bypass them. You then get hit by the gameplay tedious event.

Will the editor support hubs, eg a city map, with many exit points to different missions, or will it be linear, as in load mission, end, load next mission, end. I remember the quake that was made with the doom 3 engine having a spaceship as a hub, that went to different places from the one exit. If it can do hubs then you can have your contacts in the city hub, that send you on missions from the exits from the hub. If it cant do hubs then it'll be contact map, end, mission map, end.
