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

Some people might like it if it's done the right way. I think I'd like it. Maybe something P1 does would release a monster on P2. This wouldn't be to hinder P2 but ultimately to help them... Like removing something, maybe a metal bar that can be used to open a chest to get a key. But removing the bar releases a chain that holds the gate closed to where a monster is. I feel like a kid rambling off these scenarios, but yeah... There's potential here. There could be added pressure to make sure you don't screw up, and you can also wonder if the other player is going to do well or not.

As for communicating... I don't like the idea of 'radios/walkie-talkies' or whatever (if we are indeed thinking of implementing such a thing in a game like Amnesia / pre20th Century). Maybe tubes where 'voice chat' can be used. Once away from the tubes you couldn't communicate any longer. If you don't have 'voice' capability on your end - then you could send capsules with typed messages.
