Crisis Mountain is a platform game written by David H. Schroeder for the Apple II and published by Synergistic Software in 1982.

In Crisis Mountain, the player must defuse bombs left in a lair below a volcano which was abandoned by terrorists.

The player runs, jumps, kneels, and crawls through a volcanic lair, attempting to reach bombs with timed detonators.

After all bombs have been dealt with, the player is given the accumulated time for a "bonus run" where the goal is to collect valuable items left by the terrorists.

If a boulder is blasted from a nearby lava pit, Bertrum will dart toward it for a quick inspection, determine the rock is not prey, and fly off to another part of the cave.
