Just Cause 2 has another beta weekend planned for the multiplayer mod, and it starts tomorrow morning at 4.00am EDT/8.00am GMT and lasts for 48 hours. New features include: Extended Passenger Sync, added basic server-side Lua gamemode scripting, and “drastically improved” weapon accuracy and sync. A few bug fixed have been applied as well, and you can look over the changelog here. Have fun. Thanks, PCGamesN.
