its boring

great concept however you get tired of doing same stuff. Nice to have free build mode. Give 60min trial ago cause you may enjoy the game

The Frame drops

I play this game on the PC and i am a huge fan of it, but here on the xb1, the frame drops are terrible and almost unplayable, I planned to stream this game but now I'm really debating whether I want to play this at all, still a great game, but this is all the stars I can honestly give, good job with it though...multiplayer hint hint??? :D

Don't Waste Your Money

One of the worst ports I've played, runs at like 5 - 15 fps.
