Dr. Betruger teleported himself to Nevada against orders because he believed the Gates were a revolutionary tool for planetary colonization. His ambition to prove the Gates' potential and his desire to be the first human to successfully traverse them drove him to override safety protocols and warnings from Dr. Kahn.

Foreshadowing: The initial teleportation experiment already showed the Gates' unstable nature when the volunteer arrived deformed.

The demons invaded when Betruger teleported himself through the Gate. The moment he stepped through to Nevada, the Gate's power surge caused the Phobos base systems to shut down, creating an opening for the demonic forces to spill through from Hell onto the base.

Foreshadowing: The first teleportation experiment already showed the volunteer arriving deformed and insane, indicating the Gates connect to a hostile dimension.

When Joan agreed to Betruger's plan to restore power so they could use the Gate, she told Bennett it was a ruse to restore communications with the outside world. In reality, she planned to stop Betruger from activating the Gate and prevent the demonic invasion from spreading.

Foreshadowing: Joan initially orders an evacuation, showing she doesn't trust Betruger's intentions with the Gate.

Betruger killed Veronica to eliminate anyone who might interfere with his plan to fully activate the Gate.

After an Imp dragged Bennett down during the corridor battle, he was transformed into a zombified creature. When he later confronted Joan in the Gate chamber, she was forced to shoot him to stop him from becoming another weapon in Betruger's hands.

Joan seized the BFG 9000 to have the firepower needed to fight through the horde of Imps blocking the path to the Gate chamber. The weapon was essential because the demonic forces were overwhelming, and she needed to reach Betruger before he could fully activate the Gate.

Foreshadowing: The marines were outmatched by the demon horde throughout the mission.

When Joan was pushed through the Gate, she found herself in Hell, where a grotesque horde of Imps and their demon overlord Stanga awaited. Stanga revealed the demons' plan to reclaim Earth and wipe out humanity. Joan fought her way through the demonic army using plasma grenades until she found an exit that returned her to the Nevada base.

Foreshadowing: Chaplain Glover warned that the Gates were demonic portals leading to Hell.

The Gate began to reactivate because Betruger was attempting to slip through from the other side. After Joan was transported to Hell and returned through the Gate, she demanded it be shut down, but security sedated her. As the movie ends, Dr. Kahn expresses his belief that Betruger is trying to come through again, with only a menacing growl heard as the screen cuts to black.

Foreshadowing: The entire film establishes that Betruger is obsessed with using the Gates regardless of the consequences.

Chaplain Glover was killed during the Imp attack on the transport vessel. When the demons tore through the hull, they ambushed the crew and Glover was among the casualties, eliminating the character who had argued that the Gates were demonic in nature.

Bennett discovered the reserve power had dropped to just two percent, creating a urgent countdown that forced the team to rush through demon-infested corridors while trying to restore power before the entire base exploded.
