Here is something i was working on last week, trying to make my own version of Cod Zombies, but more advanced and requires more members to a team, just purchased Forge Networking, looks great but having issues with documentation and implementation of the networking it self. but so far got several clients moving around in a scene (all in anew project) just gota figure out how to get players to deal damage to one another and AI implemented and i can continue working on it.
