I have been programming for over 16 years and the last 2 years I decided to develop a game with net code I made myself.
This is the demo version and yes it works without VR too. You can host a game online, you must give your public IP address to other players. Clients will have to connect to play. The port needed for forwarding is 10101 UDP. The game is entirely written from scratch including the net code. The net code is only UDP but does have reliable UDP as well. I spent a lot time polishing the net code the most. A microphone is supported if it detects your microphone. The game has over 15,000 lines. The terrain can deform and form holes from explosions. Maximum of 4 tank players for now. 1 map is only used. VR should be supported, but I cannot confirm until I feel better and try my VRs on it again. I can always update the game, I am working on it daily.
