Hi, There has recently been some development in reviving Halo 2 Vista multiplayer with GFWL shutting down the master server unexpectedly in September 2015. The solution that has been developed is called Project Cartographer, a way to play Halo 2 by using the Network browser. It's NOT similar to Tuungle or Hamachi, as it's much more concrete than that. Some benefits include:
A fully functioning multiplayer
Dedicated Servers
Peer Hosted Games
Less Lag/Latency (since we're using the Network browser)
FOV changer
Mouse Fix (no more mouse lag or slow sensitivity)
60 fps lock without vsync or other third party applications
Custom Resolution support (includes 4k)
Controller Remapping (Duranzo)
A new launcher
Right now we have a growing population of around 100 players. To get more information and download Project Cartographer, please visit any of the following websites: h2v.online http://www.halo2vista.com/
