I already played the demo and now EA
The graphics and art style are really unique and the gameplay takes inspiration from Thief and Dishonored. It relies heavily on stealth and that you stay in the shadows so you can get close enough to your enemies until you can do "stabby stab stab" on them. The atmosphere is great and really immersive, at the moment Gloomwood has "only" 8 hours of content in the form of 5 levels/areas but these areas are surprisingly large and very detailed. The inventory system reminds me a lot of the RE4 inventory system, I like it.
Can't wait for more!

Update market district & Underport :

Great big new area with new lore, enemies "puzzles" and a merchant. It was kinda difficult to find out what to do and where to go but that was due to the fact that it has been a while since the last update. The other problem for me was that your movement speed is so damn slow which is really annoying because the game pretty hard and you die a lot. So you have to run back and forth to solve the puzzles and find out what to do. It kinda drove me nuts. You also get 1 one gun but sadly at the end of the level so I couldn't really use it but overall a really solid update.
The new Underport area is indeed large but overall more of the same of what we already got and nothing really special at the moment.
