You are part of a four-man CIA covert ops team sent on a one-way mission inside the Al-Shakkur defense complex to extract scientist Victor Mensch, who holds the formula for a new nerve gas compound inside his head. At least, that was what they told you in the briefing. Now, you're on foot and inside, and have to quickly come to grips with two newly discovered facts - one, things aren't the way that you were told in the briefing; two, the CIA wants no survivors from this attack, and that includes you and your team.
