released a new Coop Pack on our forums
Quote Grimes :
The Co-op map pack consists of quality and fun Co-op missions to play with friends and team mates. Each mission has marked objectives that are realistic and possible but challenging to achieve. Most of the missions in this pack do contain full briefings and tasks in game that will lead the player like Command while playing. Variable settings of Norrin's Revive Script is included in nearly all of these maps making it more of a fun, team oriented gameplay. No addons are required for any of these maps at this time, but that may come in the future.
