Appearances

Half-Life: Decay

When Dr. Gina Cross and Dr. Colette Green arrive at the control room of the test chamber while receiving instructions from Dr. Richard Keller, Rosenberg interrupts and voices his concern to Keller over having the anti-mass spectrometer run above 90% capacity, which is past the safety buffer zone for the equipment. However, Dr. Keller dismisses his concern and states that the administrator's orders for this were clear. He tells Rosenberg that he can either stay and watch the experiment or return to his labs. Rosenberg decides to remain while the resonance cascade is imminent.

After the disaster, Rosenberg believes that their greatest responsibility should be to the safety of the employees at Black Mesa. Keller thinks that they should attempt to reset the displacement fields first, but he later agrees with Rosenberg and they eventually come up with a plan to contact the military so that they can, as soon as possible, help and evacuate the facility. Later Gina and Colette escort Rosenberg through the Hazard Course, now a dangerous route, to a satellite communications center where he is finally able transmit a distress signal. Dr. Rosenberg decides to wait there for the military, unfortunately this is the last time he's seen in Decay.

Half-Life: Blue Shift

After a unspecified time after the events of Decay to Barney Calhoun's rescue of him in Blue Shift, he clearly discovers the military's ulterior motives of silencing all of Black Mesa's personnel and, with the help of a handful of other scientists, tries to enact an escape plan to get out of Black Mesa alive. However, during this time he is captured by the military and held in a freight car as a prisoner. Meanwhile Barney Calhoun discovers a colleague of his, Harold, in a office who is fatally wounded. Before Harold dies he instructs Calhoun to find Dr. Rosenberg and help him with his plan. Calhoun makes his way to the train yard, while overcoming the soldiers in his path, and frees Dr. Rosenberg. Rosenberg tells him that their plan is to use the old equipment in the prototype labs to teleport to safety.

Rosenberg leads Calhoun to the unused part of the complex where two other scientists, Walter Bennett and Simmons, are already preparing the machine. Rosenberg instructs Calhoun that he must go to Xen in order to activate and align a relay device to be able to accurately set their destination outside the facility. Calhoun travels to Xen and is successful in his task, but after returning back to Earth, they discover that they need another power cell to replenish the teleporter's power in order for their escape. Calhoun makes his way down to the lab's sub-basement and acquires a newly charged power cell and delivers it to Rosenberg. Rosenberg then initiates the system and brings it online. Dr. Rosenberg and his colleagues safely teleport to a unguarded access tunnel while the military breaks into the lab when Calhoun is about to teleport. Fortunately Calhoun narrowly makes it out alive and joins up with the team. They get into an SUV and drive safely away from Black Mesa.

Trivia

• While in Blue Shift's training course, if the player looks to the right side to the observer's window during the duck-jump portion of the training he can see Dr. Rosenberg observing Calhoun.
• In Decay the player can hear Dr. Rosenberg's voice, when they are temporarily caught in a harmonic reflux, calling after Barney Calhoun through the portal (when the player is about to leave Xen in Blue Shift).
