Important note: Like other custom maps you will have to download this from the in-game map browser. Go to the mission select menu, then to custom missions and to "user missions" and search for the map name in that browser.
This is quite a straight forward guerrilla style single player mission. It shouldn't be too challenging if you've already beat the campaigns and know how to micro manage commandos.
Briefing: "Commander, as you no doubt know the situation following Kane's disappearance has become... Dire. We have located a GDI detention facility in this valley. Destroy the cell blocks, free any soldiers still loyal to the Brotherhood and do what you like with the cowards who willingly surrendered. An inside agent has opened a way for you and he may be of further assistance to you if you can keep him alive. Good luck."
