Modder Xilandro is working on bringing Superhot’s combat into Fallout: New Vegas, and it looks damn cool. Here’s some video:
It’s all there: weaving between bullets, deflecting bullets with a sword, slashing enemies to ribbons, etc. People don’t get quite so… explodey in Superhot, but it’s like my grandma always used to say: the more entrails, the better. Don’t ask.
The mod’s not out yet, but it should be soon. Also worth noting: this person is making a flyable fighter jet for Fallout: New Vegas as well. Fallout 4‘s Creation Kit might be around the corner
