Konami will release a free update for Metal Gear Online next week that adds a new 'Bomb Mission' mode.
"In the new mission, the offensive team's objectives will be to detonate a bomb at a targeted location in the map and protect it until it explodes," says the release.
"The defending team must protect its stronghold and prevent the planted bombs from detonating by using a special coolant to nullify an activated bomb and stop the attacking team from approaching the base.
"To complete the mission and come out victorious the attacking team must detonate the bomb within the mission time limit if they fail the defending team wins."
The Bomb Mission update goes live on January 27.
