alpha squad has been captured by the enemy and is being held prisoner in a fortress overhanging a canyon 30 miles due west from your current location. Intel reports that the cliffside the fortress is on is loaded with explosives, ready to go off at any minute so stealth and coordination is key. You are to infiltrate the base via the air conditioning system then make your way through the compound to rescue alpha team being held in the middle of the facility. Absolutely no-one must see or hear you during this mission or they will detonate the charges on the cliffside, destroying the entire base with you. Should you succeed in rescuing alpha team, rappelle down the canyon's side to the floor and make your way north out of the canyon and wait for your next assignment.
hows that?
