Fuck people who say this.
Also, I thought they were cut, but then I found a lot of servers playing No Mercy, so I don’t know.
Only reason i said this is because the maps aren’t made for versus and are one sided. Also was so exhausted didn’t want to type anymore. No mercy and blood harvest are already set as versus. Basically if you copy the maps and .nav mesh from the other campaigns so you have a copy and the original. In copy you add vs after the l4d prefix so it would read l4d_vs_airport01 etc, for the bsp’s and nav mesh, it allows it to play versus mode on there. But since the maps weren’t edited there is probably going to be balance issues for the map, and ladders for the infected can use not marked as they are in the regular versus maps.
