U2 is still like, not even in alpha. It is nowhere near ready to “release” even as an easter egg like OPERATIONMAPLELEAF. There is no survival elements or any survival map, because the core mechanics of the game are still being debated / played around with. U2 coming public even next year sounds unrealistic at this pace, although @MoltonMontro makes it sound like lots of technical progress is underway that the dev isn’t bothered to write about since it’s not interesting.
