In this thread discussion, at least until the game is out, anybody in the forum may pitch in what they think/have heard on what will be in Amnesia 2. If you haven't already, you should check out their site (http://www.nextfrictionalgame.com/)
Below are my a few of my thoughts:
1: Using Penumbra, as Frictional Game's first series, terminology I expect to see some form of Flashlight and Glowstick. Amnesia 1 had the Lantern (which took a lot of oil like batteries for the Flashlight) and Tinderbox (while it didn't light on its own, it lit up candles that never went out). Seeing that the year will take place in 1899, I'm not sure exactly what lighting they will have, but I expect something in between the two games. Something like early Flashlights and Tinderboxes.
2: Both Penumbra and Amnesia 1 had someone talking to you at certain times. Penumbra Red in the first game, and Amabel in the sequel (granted Clarence also talked to you, but he wasn't out to help you). In Amnesia 1 it was more of you remembering what your character did before taking the Amnesia Potion. Considering how the main character starts out in the teaser, I'm thinking something in between the two. Flashbacks to the tragedy in Mexico, and maybe somebody in the building Oswald's in.
3: Both Amnesia 1 and Penumbra both had an enemy of some sort that you couldn't easily stop and can kill you in one shot. In Penumbra it was a Rock Worm, it had major 3 times damage than your health. The downside is he can't see beyond vibrations and is so big that he can't easily sneak up to you in corridors. Amnesia 1 actually had two monsters that fit this category, the Brute and Shadow. While the Rock Worm is stronger, the Brute is scarier because it is humanoid so it can fit in corridors and pop up unexpectedly. As for the Shadow, it's only when it is moving rapidly does it fit in this category. It can slip through all sort of places and kill you in one hit, but Shadow reminds me more of the Rock Worm. If I had to pick a monster I would pick something like this fella from the Call of Cthulhu LCG http://www.cardgamedb.com/slir/h288/foru...421187.jpg
4: I like the idea of multiple endings Amnesia 1 introduced, so I expect one in this game.
5: Both Penumbra and Amnesia 1 were H.P. Lovecraft style stories/universe. I would like to the Lovecraft Universe in the next game. Now I've so far have not read any Lovecraft book, but the Call of Cthulhu LCG does show off a lot of Lovecraft monsters and elements that would easily fit in these games. Just the Rock Worm is based on the Lovecraft Dhole.
