released a new version of this mission pack in the BI forums
where he fixed an error in one of the missions.
Quote mchide :
I decided to share some of MP missions. Some of them were played on Zeus, and most of missions we played on our SBP nights. Some are hard, some are simple. Note that all coop missions have only group respawn and offcourse spectating mode after that. AD missions dont have respawn. AD missions were designed around time. So if you die, you will not wait too long on spectating script.
