Uzi, N and V are the only three left in a zombie apocalypse. They had been chased from their home camp by a hoard and had to run, seeing a cave they hid inside but they're not alone...

you can be a worker drone, disassembly drone or a zombie and no they are not the same as Uzi they are like actual zombies falling apart and rotting. and one more thing, because of Uzi being a solver host/user she can't be infected.
