The events of Kill zone, most of southern Vekta is still under Helghast control.

The enemy still controls large parts of the planet Vekta, and though the ISA armies are fighting hard, they are losing ground.

In Sniper Kill Zone Shooting, two months after the events of Kill zone, the Helghast have been dealt a hefty blow from the last game,

but the war is far from over.

The rules of war have been cast aside with the sadistic Helghast General Armin Metrac,

employed by the Helghast Emperor Scolar Visari to use brutal measures in order to seize the initiative after their past defeat and strengthen his position further.

Metrac and his right-hand man, Colonel Cobar, are planning to capture three key figures of ISA, and their plan ends up successful.

Returning as Jan Templar, players are sent on a covert operation to save hostages captured by Metrac, while ISA troops continue the fight for liberty.

Rico Velasquez, Jan's friend on the battlefield, often assists him on his way through the enemy lines.

Shadow Marshall Luger, another of Jan's partners, also helps him.

As Metrac captures ISA Minister of War Heff Milcher, scientist Evelyn Batton, and ISA General Dwight Stratson, Jan is sent on the rescue mission.

After a set of military operations, Templar is closely following the trail of hostages and pursues Cobar, who has taken Milcher and Stratson.

Milcher is then killed by Cobar, but Jan is nevertheless successful in defeating him, even though Cobar was piloting a personal walking tank.

Cobar reveals that there is a traitor in ISA command who is helping the Helghast, but is finished off by Stratson before he can say who the traitor is.

The next step for Templar is to assault Metrac's mountain fortress and rescue Batton. Luger aids him on the mission.

There, he fights many of Helghan's elite warriors (including a giant cybernetic unit) before encountering and killing Sniper Kill Zone Shooting in a final showdown.

Afterwards, Templar locates Evelyn and escapes with her just before the fortress is destroyed.

The game's outro marks the beginning of Kill zone, as Liberation hear Visari speaking of nuclear weapons which he intends to use on ISA forces.
