Before the Great War, the center was used to direct visitors to various locations in the park. Unbeknownst to guests, the Nuka-Cola Corporation operated a highly secured cloning facility underneath the location. Experiments were performed on animals such as polar bears and anteaters.
However, a radical animal activist group known as the A.F.A.D. was alerted to activities taking place in the cloning facility. Attacks commenced against Safari Adventure staff, and the welcome center was vandalized. With the security team being understaffed due to Project Cobalt, they managed to contact Dr. Hein on the morning of the Great War, impersonating a park employee in order to lure him out to the Angry Anaconda. He was then held hostage, and the facility placed under full lockdown.
Following the War, the remaining survivor, Dr. Darren McDermot, attempted to use the cloning machine to repopulate the world with animals. Following raider activity, he attempted to create a creature to help prevent the facility from falling into the wrong hands. Instead, he accidentally created the gatorclaw from the genetic material of a chameleon, an alligator, and a dead super mutant. He was wounded and driven out, eventually succumbing to his wounds in the care of Cito.
The Welcome Center's entrance leads to a gallery overlooking the main room, with stairs leading down to the main floor either side of it. The room's middle is occupied by desks and its walls are lined with empty displays for animals and the space is initially patrolled by a gatorclaw.
In the back of the room, there is the entrance to the Nuka-Gen replicator facility locked with a terminal requiring Dr. Hein's passcode to open. A corridor leads down to the facility's research hall with holding spaces for animals, cold storage sections, and several workstations. Further on is the partially flooded Nuka-Gen replicator floor guarded by an albino gatorclaw and a normal gatorclaw; the Nuka-Gen replicator controls and generator can be accessed from here. Opposite the stairway access to the room is a broad pipe with an openable hatch leading to a door up to the river running through Safari Adventure, locked with a terminal located nearby. Once the power is back on, going back to the terminal will give you the option of replicating gazelles. Activating this will overpopulate the safari with gazelles. Additionally, once activated, it cannot be interrupted.
