Shaka,
When you build or make your MP game FPSC saves a complete folder for it in the mygames directory - this folder you have to give to everyone you wish to play your game. So you have to send or make it available to them at some location so that they can get it.
Wheteher or not you zip it is a matter for you to decide - if you do all users will have to unzip it when they get it. Zipping it will make it smaller for them to get hold of.
All users reaaly do need to keep the game folder in the same place on their machines say in Drive C.
