The ending reveals that dinosaurs have escaped into the modern world, creating an irreversible ecological crisis. With the collider destroyed but the creatures already present, the film suggests these prehistoric predators will now spread and disrupt contemporary ecosystems indefinitely.

General Borodin commissioned the particle collider to open a wormhole that would send prehistoric creatures into the present. The Russian compound was deliberately releasing dinosaurs into the Vietnam jungle, likely as a biological weapon or experiment during the Cold War era.

While the immediate threat of the collider is neutralized and some survivors escape, the mission is strategically a failure, the US lost key team members including Baker and Keyes, the ecological threat of dinosaurs spreading remains, and Colonel Jericho's cover-up ensures no official accountability. The surviving Vultures are left to confront a world where dinosaurs now roam free.
