I was looking around in Desura and came across this game, and I though "this would be great for GOG". It's a french indie sci-fi FPS-puzzle-platformer. Kind of reminds me of Portal, but with with different mechanics. No portals and no test chambers, here you jump from platform to platform, somewhere above the clouds (don't look down!), with the help of a cool looking gun to help you navigate and solve environmental puzzles. You're on a time limit though, so action is quite fast paced. It uses the Unity3D engine and has the most beautiful graphics I've seen on that engine.

It's was released on October 17, 2014 in both Steam and Desura. You can check the official website here and a "Let's Play!" of the alpha version here. And yes, it has a DRM-free version, so I think it shouldn't be difficult to bring it here.

I've added it to the GOG wishlist (it wasn't on there yet!): DeadCore

I hope it's ok if I bump this. It really seems like a great game.

French indie? Is it in black and white? Surrealistic?

Just kidding. Looks good, voted.

It popped up on Steam yesterday also - http://store.steampowered.com/app/284460/

It have Namco/Bandai as publisher there. Got good user reviews so far. Looks interesting.

This game looks like it will make me lose my ever loving mind. +1 voted :)

Why do all games that are inspired by Portal kinda look like Portal? In this case just on steroids.

Anyway, looks decent, voted.

Looks half-interesting as a puzzle game but sadly I can't stand time limits and it seems to be very quick reflex kind of game too.

Looks good to me. Voted.
