BattleCity Classic was the very first online multiplayer game I ever played in the late 90's.
With permission from the creators I recreated the game completely in C++. We had a successful run with active players in the mid 2000's.
I have updated some libraries and the game will compile with Visual Studio 2017 Community. If you run the server and client profiles you will create a localhost server and be able to connect to yourself and play the game.
