A major crossover is on the horizon for fans of Reverse: 1999 and Ubisoft’s Assassin’s Creed series. Developer Bluepoch has officially announced a collaboration event set to launch in August 2025, merging the time-warped narrative of Reverse: 1999 with the iconic historical stealth gameplay of Assassin’s Creed.

The news dropped alongside a teaser trailer that’s now live on YouTube, offering a brief but atmospheric glimpse into what players can expect. Though the full details are still under wraps, what’s been shown already has stirred up plenty of excitement across both fanbases.

A Teaser Shrouded in Mystery

The teaser opens with Vertin, Reverse: 1999’s enigmatic Timekeeper, wandering through a rain-soaked street under a gloomy, cloud-heavy sky. She’s holding an umbrella as the camera lingers on her slow steps. The quiet scene is suddenly interrupted by a burst of light in the distance revealing the unmistakable Assassin’s Creed insignia, glowing in the mist. It’s a chilling, cinematic moment that suggests something big is coming.

While the footage doesn’t reveal specific gameplay mechanics, the blend of visuals already teases a meaningful crossover. It’s clear this isn’t just a cosmetic partnership that feels story-driven and fully integrated.

A Blend of Worlds: Assassin’s Creed II and Odyssey

According to the announcement, this crossover will pull from Assassin’s Creed II and Assassin’s Creed Odyssey, two of the most celebrated entries in Ubisoft’s long-running series. Whether through character appearances, themed missions, or interactive storytelling, fans can expect a crossover that respects the identity of both titles.

The classic Assassin’s Creed tagline, “We work in the dark to serve the light,” makes an appearance in the trailer. That alone hints at how deep this collaboration might go—possibly bringing shared themes of secrecy, sacrifice, and timeless conflict into the Reverse: 1999 universe.

What Makes This Crossover Exciting

This partnership has the potential to offer something more than the usual event tie-in. Reverse: 1999 is known for its strong narrative, mysterious tone, and layered time-travel elements. Pairing that with Assassin’s Creed’s historical depth and moral ambiguity could result in something rare, a crossover that actually enhances the storytelling of both worlds.

If done right, we could see unique story arcs, custom maps inspired by Renaissance Italy or Ancient Greece, or even playable characters drawn directly from the Assassin’s Creed legacy. Whether you’re a longtime fan of Ezio Auditore or Kassandra, or just exploring Reverse: 1999 for the first time, there’s a lot to look forward to.
