I made a poll/thread about this months ago, maybe last year to see who was interested in Sundered. I am now curious again considering the game is almost here, though the exact date hasn't been announced. I just know it comes in July. I've also made a couple of threads about Jotun (the game from the same developers) since it is one of those games I feel not a lot of people played when I'd imagine some would like it very much. I assume it's due to the lack of coverage it got (Giant Bomb unfortunately never did a quick look of it). That's somewhat off topic but I'm just saying, now would be a good time to play it if you're interested in Sundered. Sundered is a Lovecraftian, fast-paced Metroid-vania that has huge, challenging bosses.
The levels are procedurally generated, which at first was one aspect that turned me off, but from what I understand it's not as bad as it sounds. It also has dynamically spawned enemies. The art, in my opinion, is fantastic, and I have to imagine the music is going to be wonderfully intense if Jotun is any indication; it's the same composer. It also features multiple endings. At first glance, if you watch some of the videos that show the number of enemies on screen in some parts it may look cheap considering it may be hard to see where you are, and just the simple act of dodging seems iffy, but the more I watched it seems less of an issue as long as you know how the enemies attacks work.
It actually looks like a game where you'd see a bunch of people try and attempt to get through sections without getting hit, especially bosses. The game is going to be on the PS4 and PC, but I believe they're perhaps looking to extend the release to other systems later on. I'm glad there is finally a wiki page for it too; last time I made a thread about the game there wasn't. I would post a video of the game for those that haven't seen it, or even for those that have, but you can check YouTube yourself for the handful of videos out there that show the game off. To answer my own question, yes I am excited about the game. I really enjoyed Jotun and this looks even better honestly since it's faster-paced and the Lovecraftian style interests me more than Norse mythology. What about you?
For even more insight about the game, check this page.
Edit - Oh, one last thing. Another game I recommend before playing Sundered due to a great soundtrack and artistic design, cool and challenging boss fights and side-scrolling gameplay would be Outland. That's also another game I feel, like Jotun (though not to Jotun's extent) I have the feeling not enough people played despite perhaps enjoying it.
