Batman: Arkham Origins - 10 Coolest Easter Eggs, Secrets And References Explained

9. The Secrets Of Wayne Manor

It's no surprise that Arkham Origins' Cold, Cold Heart DLC is just as overlooked as the main game itself. This piece of post-launch content takes place at New Year, a few short weeks after the Yuletide festivities of Origins' story, and features a retelling of Mister Freeze's origins, one that takes a huge amount of inspiration from the seminal Batman: The Animated Series episode, Heart of Ice.

Cold, Cold Heart features several references to that episode, including Batman's "humanitarian" line initially spoken by Kevin Conroy, as well as the snow globe that features Victor and his wife Nora. Further still, WB Montreal also elected to pay reference to Joel Schumacher's Batman & Robin, showcasing several of Freeze's henchmen making ice puns, and even placing Pamela Isley in GothCorp before her transformation into Poison Ivy, referencing the duo's partnership in said film.

By far the coolest details in Cold, Cold Heart, though, are contained within Wayne Manor. Montreal gave players full reign of the Batcave in the main title, and did the same with Bruce Wayne's stately home in the DLC.

The location is filled to the brim with callbacks to the comics and related Batman media, including the red phone from the sixties show, the grandfather clock entrance to the Batcave, Martha Wayne's pearls, a selection of paintings that trace back the Wayne family lineage, and - perhaps best of all - what may even be a skull Batman retrieved alongside Detective Chimp from Batman: The Brave and the Bold.
