Character Role
You are a Pinkwater Security mercenary whose shore leave on Eros spirals into a lockdown and conspiracies involving the protomolecule and Osiris Corporation.
Main Objective
Escape the lockdown, secure command of a top‑tier spacecraft, recruit and maintain a crew, unravel a system‑wide conspiracy, and influence the escalating tensions between Earth, Mars, and the Belt.
Captain Origins
Craft your captain with origins from Earth (Earther), Mars (Martian), or the Belter culture—the choice influences dialogue, relationships, and how factions perceive you.

The Expanse: Osiris Reborn positions itself as a proper successor to beloved sci‑fi RPGs—melding the tactical, emotion-driven choices of Mass Effect with the gritty realism and political nuance of The Expanse universe. With high production values, deep squad and romance systems, and a ripple-effect narrative design, it could become the flagship sci-fi RPG for years to come.
If you loved the Mass Effect series, crave morally grey narratives in hard science fiction settings, or simply want to dive into the solar system with your custom crew, this is one to keep on your radar. Wishlist it, back it through a Founder’s Pack, and stay tuned—big reveals are likely around the corner.
As a massive Mass Effect fan, I’ve spent years searching for a game that could recapture that same sense of space-faring wonder, squad-driven choices, and cinematic storytelling. Then I saw the reveal for The Expanse: Osiris Reborn — and my jaw dropped. This could be it. The moment the trailer kicked in with a sweeping view of distant stars and a crew of morally complex characters walking into the unknown, I felt that same butterfly-in-your-stomach feeling I had the first time I stepped aboard the Normandy.
Let’s be honest: we Mass Effect fans have been starving. While nothing can ever truly replace Shepard’s journey, The Expanse: Osiris Reborn feels like it’s speaking directly to that part of me that craves epic interstellar narratives. It’s not just a space game — it’s a grounded, gritty, and politically charged sci-fi world with high-stakes decisions, alien mysteries, and fully-voiced characters who actually feel human. That’s the secret sauce, and Osiris Reborn looks like it has it.
Set within The Expanse universe, which is already rich with tension between Earth, Mars, and the Belt, this game promises something special: a chance to experience the politics, the danger, and the scale of the solar system through the eyes of a new, original character. You're not playing as a soldier or a chosen one — you’re a survivor, a pilot, a leader who has to navigate a galaxy teetering on the edge of chaos. That setup already has my attention.
What excites me most, though, is the game’s approach to crew dynamics and decision-making. Just like Mass Effect, Osiris Reborn seems to place a heavy emphasis on building relationships, making hard calls, and living with the consequences. Every crewmate you recruit has a backstory, a perspective, and — potentially — a breaking point. That level of depth makes your squad feel real, not just walking skill trees. I want those long, tense conversations in the mess hall. I want to choose who I trust and who I keep at arm’s length. And I want to see how those choices play out when everything hits the fan.
And let’s not ignore how gorgeous the game looks. The visuals are slick and cinematic, but still carry that gritty realism that The Expanse is known for. Zero-gravity environments, asteroid bases, stealth ships, and massive orbital stations — it all looks straight out of a sci-fi film. I can already picture myself floating through an abandoned ship with only my flashlight and the eerie sound of the hull creaking. The tension, the immersion — it’s all there.
What really seals the deal for me, though, is that Osiris Reborn isn’t trying to copy Mass Effect. It’s carving its own path with a grounded tone, realistic physics, and a darker story. It respects the player’s intelligence and wants to build a world where every choice matters — morally, politically, and emotionally. That’s the kind of storytelling I crave.
So yeah, I’m all in. I want the late-night conversations with my crew. I want the impossible choices. I want the quiet moments looking out a viewport as the stars drift by, wondering if I did the right thing. If The Expanse: Osiris Reborn can deliver even half of what it promises, it’s going to be the kind of game I remember for years — just like Mass Effect.
Let the journey begin.
