Multiplayer/Co-Op & Frictional Games? NO!!!

[Tenacious]

I think multiplayer would not be a wise decision. Let me start off with the most basic observation: we don't know what Daniel looks like. The only other characters we meet in-game besides the monsters are Agrippa and Alexander, and even they aren't normal. I can only imagine that player models would have to be referenced to Daniel, but because we don't know what he looks like, we can only guess. They would have to use some kind of model for players and I doubt they'll use monster models.

The game simply wasn't designed with multiplayer support. Perhaps they may implement some sort of multiplayer in their next release, but I'm pretty sure they'll leave Amnesia the way it currently is.
