Provox games are currently working on a multiplayer version of Spaceforce2.
Based on a tool developed by the lead programmer of the game (aka Leva Opaki) Spaceforce might become an interesting choice for the Scifi MP community.
This tool is able to run a Spaceforce server via console commands and connect to it via client versions.
Unfortunatly this is just an unofficial project at the moment. The official statement is that there wont be an official MP version of Spaceforce Rogue Universe or a new game with this multiplayer feature anytime soon.
If Provox Games will ever release a Spaceforce 3 is not sure but we hope that Provox will realize the potential of that game and the new multiplayer feature in order to great an even better game.
Detailed information about the Spaceforce 2 multiplayer tool will be published here later.
