Years later, Bruce would begin to use the caves to store his equipment secretly as the vigilante, Batman, and eventually transformed the cave itself into a base of operations for his continuing war on crime.
Before Arkham Origins IncidentEdit
Bruce investigated the den of bats and discovered a system of caverns that stretched beyond his 150 acre estate into most of Gotham City. Over time, he converted the caverns into his base of operations.
Bruce designed a training station for him to stay in shape, a workshop to work on his gadgets, and a secret dock for the Batwing. The Batsuit was housed in a stand-alone container, which allowed it to breathe and contract after each use, so as not lose its shape. The Batcomputer was linked to a experimental device Bruce borrowed from Wayne Enterprises called Detective Mode and a video surveillance system was used to keep tabs on all of Gotham City. He setup secret entrances and exits throughout cave that lead to Wayne Manor: one in the Study and the other in the Wine Cellar.
Arkham Origins IncidentEdit
The Batcave was accessible in Batman: Arkham Origins and worked as a hub to access Challenge Maps, Alternate Batsuits, and talk to Alfred. It was first shown in the opening cutscene, with Bruce entering the cave and suiting up. He left via the Batwing to go to Blackgate Prison. From then on, the player was free to come and go from the cave whenever they pleased.
However, going to the Batcave was also part of a mission at several points during the story. First, before the player could enter the GCPD and access the National Criminal Database, they returned to the Batcave and retrieved the Concussion Detonator, a new gadget from the workbench. Second, after Bane deduced Batman's identity, the player returned to find the cave destroyed and a beaten Alfred lying buried under rubble toward the bottom of the cave. After this, whenever the player returned to the cave, it was still in the destroyed state, with several parts of it still destroyed.
Cold Cold Heart IncidentEdit
In the DLC, there was shown to be two entrances to the Batcave. The clock in the Study (although the player could not use this entrance because of all the guests in the room), and in the Wine Cellar as a failsafe. In the Batcave, some of the damage from Bane's attack was fixed by the time of New Year's Eve. But the workstation and Batmobile prototype were still gone. It also appeared to be somewhat expanded with a new elevator that lead down into the cave by the Training Area from the Wine Cellar.
Between Arkham Origins and Arkham Asylum IncidentEdit
Arkham Asylum IncidentEdit
Arkham City IncidentEdit
Nightwing and Robin were botth seen in the Batcave participating in a training simulation of TYGER Guards attempting to take over the Batcave, which was staged for them by Batman before the Arkham City Incident. After Bruce Wayne was captured and incarcerated in Arkham City, Hugo Strange's TYGER Guards attempted to take over both Wayne Manor and the Batcave to take advantage of Bruce being in Arkham City. Luckily, Nightwing, Robin, and Alfred stepped in to defend the Manor, took out the TYGER Guards, and managed to keep both Wayne Manor and the Batcave safe.
Arkham Knight IncidentEdit
The Batcave did not appear in Arkham Knight, but in its place, there were 3 variants: The Clock Tower, Panessa Studios, and Bruce Wayne's Office at the top of Wayne Tower. It is unknown if the Batcave was destroyed during Knightfall Protocol, although it is is possible that Batman and Alfred somehow made it into the Batcave right before Wayne Manor was destroyed if the Batcave wasn't destroyed. If this is true, then it is more than likely that Nightmare Batman is truly Bruce Wayne.
- The Batcave Predator Challenge Map was featured in the Challenge Map DLC pack for Batman: Arkham City.
- The Batcomputer mentioned how many TYGER Guards remained as well as those that were taken out.
- Near the Batwing, on the ground beside the grate, was the Grapnel Boost and several of the containment pods that housed the Batsuit at the beginning of the game.
- There was a statue construct of Batman in the hallway to the right of the T-Rex in the Challenge Map.
- There was a reference to Jason Todd, the second Robin, in the Predator Challenge Map of the Batcave. The Batmobile was without its tires, which referred to the first encounter between Jason and Batman, when Jason was trying to steal the tires from the Batmobile and in Arkham Unhinged, there was a glimpse of Jason's Robin uniform on display in the cave as it was a memorial to him when he was killed by the Joker.
- On one of the monitors in the Batcave. there was a video that showed the Cathedral in Arkham City. The other one was from Arkham Asylum.
