Doomstar Relic (Outlanders)

When a rebellious member of the Ragnarville Trust discovers a subterranean laser-fusion plant dating back to before the nuclear holocaust, he devises a plan to take over the ville. But by restarting the fusion process to power his stronghold and create a holographic assassin, he also unknowingly initiates the self-destruction mechanism in the plant. Kane and his team are sent by Redoubt to handle the situation--and find themselves at war with the rebel forces, an unstoppable killer and a doomsday program set to destroy the Earth a second time.
