I am working with @adriansnetlis on this game.
We plan on having 2 game modes. The first is you fight against AI and the second is multiplayer. I already set up a simple network script that can accommodate up to 255 players but I will probably limit it to 5 to minimize network stress for the server. Below are some screenshots. The first is of the multiplayer test. And to be clear, it is not a LAN multiplayer (despite me running it on one system). I am hosting the game on a server which will allow anybody anywhere to join the active game. The multiplayer game will be endless. When a player dies they simply re-spawn back into the game. Total kills will be displayed on a temporary leaderboard that resets when nobody is left in the game.
