Porkins stayed up all night playing Liftoff, so you don't have to. But you probably still should!
For an 'Early Access' title, this game is in great shape, and very playable. Albeit leaving you needing a couple things (camera angle adjustment and flight ceiling) to go any faster. I think it has a good chance of being the go-to FPV video game experience, especially with the industry partners it has, and HELL YEAH! it even includes our good friend +metalldanny's logo in game. I hope they do some mo-cap and actually put Danny in the game.
I was going to do this as a review, but in my opinion, it's not ready to review, so I just edited some of my footage to give you an idea what to expect.
