Official Summary Edit

Evil gets an upgrade!

In the far future, Jason Voorhees has been resurrected as an invulnerable monster. Military scientists, keen to create unstoppable super soldiers, are anxious to utilize Jason's regenerative powers and killer instinct. But Jason is no lab rat, and escapes into an underground complex to continue his murderous mission. The scientists will soon find out, to their horror, that evil cannot be harnessed and cannot be stopped.

Full of futuristic thrills, action and good old-fashioned slasher mayhem, Jason X: The Experiment proves there's only one thing worse than an unstoppable killer.

Two of them.
