Act 2

In the beginning of Act 2, Gordon wakes up to see his companions (and a skeleton) looming over him, with the crew acting as though they can no longer see the skeleton beside them. They continue on with their journey through Black Mesa, with the skeleton stalking them in the background. They eventually run into the pit of Tentacles and have to narrowly avoid them in order to advance through the next puzzles. Gordon encounters the skeleton face-to-face once again after shooting at it with a gun, and it uses the Black Mesa Sweet Voice on him, possibly to calm him down. Overhead, the Vox intercom announces: "GORDON FREEMAN, YOU ARE WANTED FOR PASSPORT INSPECTION," causing the team to panic over the lack of Gordon's passport on hand.

Benrey is reintroduced back into the team after appearing on an elevator, and the Vox intercom repeats his announcement once again, followed by Benrey interrogating Gordon and confirming that he'll follow Gordon as a result of his lack of proper credentials. Benrey's harassment towards Gordon resumes, and at one point, he outright shoves Gordon into a pool of green sludge. After a series of procedures, the crew is finally able to initiate a rocket-launch simulation within the chamber they encounter the Tentacles in, allowing the gas and flames to destroy the tentacles. The corpse of a guard is found later in another secluded room, which Benrey reveals to be his friend Josh, quickly blaming Gordon for his death.

The crew is quickly warped forward through Black Mesa as Dr. Coomer and Bubby announce that he burnt a Playcoin to skip ahead, and the two warn that running completely out of Playcoins results in dire consequences. Later, the crew encounters their first Gargantua, later nicknamed the "Black Mesa Golem Ape." Tommy claims that Benrey's "Song of Death" helped to defeat the creature. Benrey also kisses Gordon on the cheek when he's not paying attention.

An NPC helps direct Gordon that he needs to go to the Lambda Lab, and is quickly killed soon after as the crew moves onward, soon running into the rogue guard seen in the last Act, whom seems to murder Benrey in front of everyone. He introduces himself as Forzen, and Gordon and the crew interrogate the soldier for information, learning that Forzen is a rogue guard from "Teams Nice." When asked what his motives are, Forzen only states, "I just wanna graduate," and quickly escapes from their interrogation circle, only to be caught once again. During his interrogation, Forzen offers to give Tommy a Beyblade with three bit-beasts from downstairs if he puts his gun away, and though they nearly reluctantly comply, the crew is suddenly directed to go outside by Vox. Forzen reveals that Benrey knows the exit, and that they used to be best friends, before eventually escaping interrogation and jumping into a pit.

Continuing onward, the crew hitches a ride on one of the train-like rail carts, to which Gordon is nearly run over by it, further solidifying his crew's incompetence. Another skeleton is briefly encountered, then shot by Gordon. Eventually making their way outside, Gordon quickly slaughters a few hostile guards, and spots Benrey sitting on the ledge beside the carnage, claiming that he waited for them to arrive because he did indeed know where the exit was. Though Gordon tries to interrogate Benrey for being "buddy-buddy with those guards," Benrey quickly dismisses him without much to say.

The crew decide to take a rest here for a while, and Gordon escorts the three away from Benrey to talk to them about his suspicions on him, though they all dismiss his claims as well, much to Gordon's dismay. Coomer mentions in passing that they very likely also destroyed most, if not all, of the entire U.S. Military during their journey. The conversation takes a lighter turn as Gordon asks the three what their dreams are outside of Black Mesa; Bubby expresses desire to go to outer space, Dr. Coomer reveals his past dreams of becoming a boxer, and Tommy simply states he would have enjoyed life as normal, and mentions that Sunkist is immortal and of his own creation, possibly an experiment similar to how Bubby was made.

Benrey is allowed to stay with the crew, and Gordon suggests that instead of returning into Black Mesa, they escape by climbing over the rocky cliffs surrounding them. Dr. Coomer utilizes his Super Legs to scale the mountains at record speed and disappears for a while, only to quickly return and state that such a route would be a bad idea. "There's nothing there...." is all he can mumble in an ominous, almost traumatized tone, and before Gordon can have an existential crisis about it, Bubby directs them to keep moving forward and return inside.

Arriving in a control room of sorts, Benrey takes a seat and announces that he's editing Wikipedia articles, stating that he added Gordon's death into the wiki page for All Dogs Go to Heaven 2. Vox speaks overhead and mentions a "ROCKET LAUNCH," "ROCKET FACILITY ENTRY DETECTED," and "PLEASE ACTIVATE ROCKET." Gordon moves to the nearby room and activates the rocket launch, watching from the windows as Bubby is seen on the top of the rocket, being launched off gleefully into space. Bubby returns soon after, and Benrey re-launches another rocket. While the rest of the crew sleeps, Bubby demands that he be sent back into space, and suddenly floats out of the window and out of Gordon's sight.

Trivia

 * Dr. Coomer's experience with seeing nothing outside Black Mesa was inspired by an experience with Source game glitches Holly encountered when she was younger.
 * The official Wikipedia article for All Dogs Go to Heaven 2 was vandalized with edits of mentioning Gordon's death following the release of Part 2. It is now under protection.
