The newest game from Supergiant Games, the guys who did Bastion.
It's a lot similar to Bastion, what with similar drawing style, except this time the environment's all sci-fi. Also manly voice, this time it's the sword's. Also amazing music. Hell yeah!
The battle mechanism is a whole lotta different, though. It mainly consists of entering to a zone where time doesn't pass and where you can plan your next movements, which you will be performing at high-speed at the end of the turn.
You'll get lots of Functions AKA skills that you can use with your mighty sword. You can combine them together or you can use them as Passive skills, which allows for a hugely different battle styles. I'm lovin' it.

If you liked Bastion, you'll like this. If you like different ways of killing mobs, you'll like this.
