First of all, I will say. It is expected that anyone building a multiplayer game, has some basic (at the least) knowledge of multiplayer logic. I cannot predict what you’re building or the style, and am not building a game for you, although I will provide examples of how to do anything you will require for the core of any AAA TPS/FPS battle. Should you find something more that is required for flexibility, let me know and I will certainly take consideration.

With the above already considered. Multiplayer is a vast base. I have provided in this asset a major head-start in getting a multiplayer game realized for any TPS/FPS battle type scenario covering a majority of what you can find in any AAA game today without going too far with feature creep (or this asset would never see light of day!)..
