Blow the Mine

Mission #6 from Shadows of Brimstone (Basic Missions) on page 25

That's it! There are just too many Gates opening up and creatures coming out of the local mine to handle. When one Gate closes, two more open up around it! There's only one thing for it, you'll have to blow the mine! Collecting up all the heavy-duty explosives the local Frontier Town has to offer, you set off into the depths to find a couple of good spots to plant the charges that will collapse the entrance tunnels for good. Of course, the only trick is that you also have to get out before it blows. This one's gonna be close!
