FTW The Boss Battle
A downloadable game for Windows
Epic Networked Multi-Player Boss Battle!
Probably will work for you since I fixed the network server detection. Put server folder on the server and run the FTWServer.exe file.
Put the Client folder on each client and run the FTWClient.exe file. Enjoy!
Note that if there is no Server running the Client just hangs, and the client will NOT work on the server machine. You can join a game in progress, so just because you didn't log in before the battle starts, doesn't mean you are left out!
Good Luck & have FUN!
