## Transcript

We have the means to destabilize ourselves. A preemptive strike.
After the invasion, the blast drove everyone out. When North Korea invaded, power was their first target.
The nuclear meltdown spread radiation throughout the region. Dangerous winds have made the tri-point region between Russia, North Korea and South Korea uninhabitable.
But the North is moving back in. Crucial intel was recovered about their operations. Undisclosed to the public, beneath Hajin lies an array of military facilities containing chemical, biological and nuclear weaponry.
We believe the North is after these weapons and they not alone Rogue operators are active in the DMZ Some are paid for, others are out for themselves.
This is bigger than Hajin. If they find what they're looking for, the threat won't stop here. We're sending you in to find, fix and finish all enemy combatants.
Uncover intel about the enemy's operations. Secure the weapons before the North can. This operation is off the books, so whatever resources you need, you'll have to find yourself.
They're hunting for the weapons. We're hunting them. We have work to do.
