No More Room in Hell the long awaited Source zombie modification.
This video demonstrates a single play through of an objective tree in nay0r's nmo_broadway through the perspectives of three players. The players complete objectives in order to be extracted safely from the zombie hordes. There are multiple objective trees in the map that are chosen randomly at the start of each round, giving the experience a dynamic feel.
Remember, this is an early build and we are aware of the bugs. They will be taken care of as development continues!
