Black holes will be rare.Very rare, but if you go searching, you might be able to fnd one inside a month.We will follow the concept that black holes are wormholes, and will teleport you somewhere else. So, if you enter a black hole, it will teleport you in another black hole (it could be close or extremely far, you never know). And then, from the other blackhole, you will be able to go back in your previous black hole. So, each blach hole will have a pair. For example, blackhole 1 will warp you to blackhole 2, and blackhole 2 will warp you back to blackhole 1. A black hole will have a 0.2% chance to be a universal blackhole.That means that it will warp you to another universe.An entire universe, exactly like the other. Because if the game is called Dual Universe, and it just has one universe, it doesn't really match its title. Also, add a GPS so we can see coordinates.
