Jack Butcher is a former soldier, and now an assassin working for the
government. His contact Sabre has a new assignment for him: take out Jacques
Arnoud, head of Microkomm and an associate of the Red Storm Rebellion. They
are planning to use Microkomm’s new government contract to fund a rebellion,
and the government wants him dead. This should have been an easy assignment –
hit and run, escaping through the roof. However, seconds after Jack shoots
Arnoud, a guard bursts through the door. After narrowly avoiding capture by
the guard, a bomb blows the stairways to the roof. Jack is stuck in a building
crawling with guards and security drones who are out to get him.

Assassin 2015 is a plot-driven 3D first-person shooter focusing on combat
rather than exploration. Opening the wrong door or going the wrong way will
usually result in the player character’s death, as he will encounter a horde
of guards or drones. The player listens to the instructions of Jett Jones, the
protagonist’s only outside support, and follows her directives. The gameplay
is mostly linear and involves traversing corridors and rooms and shooting the
enemies within. However, the game features some other scenes, such as running
away from a giant robot and an elevator shootout.
