The current build is intended for Zero Hour players using Radmin VPN rooms, other local network style setups, GameRanger sessions and classic community lobbies.
Here you can quickly see whether the current compatibility matches the way you actually play online.
The current build is aligned with Radmin and other local network style sessions where Zero Hour v1.04 is still actively played, with GameRanger also covered as part of that environment.
This page is most useful for players who still launch Zero Hour through Radmin VPN rooms, other local network setups and community multiplayer environments where compatibility matters more than anything else.
