I’ve been contributing to the Forged Alliance Forever open source project since December 2016. FAF basically is a community made Lobby/Tournament/Map-/Mod-Vault project for the real time strategy (RTS) game Forged Alliance from 2007.
I’ve spent quite some time on one of their clients (Downlord’s FAF Client).
The game internally uses a peer to peer network architecture that tends to disconnect players from the game regularly. Due to this I’ve also invested some time into fixing/writing and ICE adapter lately which aims at tunneling all game connections through the local adapter and using the Interactive Connectivity Establishment (RFC 5245, candidate discovery, STUN+TURN) protocol for connecting to other players.
