"Mountain Stronghold" was a Dominion Defense Force training exercise for recruits located on Braxis. Recruits had to withstand a seven-day siege with only three days supplies. As supplies ran out the opposing force would begin bombarding the fortress for a 72-hour stretch followed by an assault. Recruits who successfully completed this scenario moved on to the "Glacier Bay" exercise.
The stronghold serves as a StarCraft: Brood War map, supporting up to four players.
