An update is available on the beta branch on Steam that adds support for multiplayer games with the following features:
- NAT punch-through with relay server fallback.
- Connectionless peer-to-peer UDP messages with multiple channels and optional reliable flag.
- Public server list of available games to play.
- Voice-over-IP for in-game chat (and taunts!).
The new multiplayer system will open up a new range of game types that can be easily created with Leadwerks Game Engine.
These features are still being tested and are only available in the Windows build right now.
