Your military intelligence sector has located with the help of a satellite the exact position of an undercover enemy laboratory that is operating for quite sometime now doing a lot of damage. You're sent there alone to infiltrate the facility and eliminate all the mercenary soldiers who are guarding this place. Shoot to kill them all up as they make their move to shoot you leaving their cover. Clear room after room until you clear the entire laboratory from the guards to complete your top secret and priority mission. After all, you were never there!
