No Project Hail Mary Game Yet? Here’s A New Way to Play With Rocky and Your Eridian OC
Project Hail Mary is Andy Weir’s 2021 sci-fi novel about Ryland Grace, a teacher who wakes up alone in space with one mission: save the Sun. In 2026 film adaptation (starring Ryan Gosling), the duo of Ryland and the rock alien Rocky captivated audiences with charming storytelling, leaving fans wanting more ways to experience their story.
As of October 2026, there’s no official Project Hail Mary Game available to play yet. In the meantime, this guide shows you how to recreate Grace, Rocky, and your own Eridian OC in Redbean – a mobile sandbox for creators and roleplayers.
Is There an Official Project Hail Mary Game? #
No, not yet. The only official Project Hail Mary game, Journey Among the Stars, is still in development and expected in winter 2026. Maze Theory is building it with Amazon MGM Studios, and Andy Weir wrote its story as an untold chapter of the mission, with you playing as Grace alongside Rocky. It’s planned for VR and several mixed-reality headsets.
The official film site also has a browser experience where you accept a Petrova Taskforce mission and make your own crew member badge, as a promotional piece for the movie, and there’s no story to continue once your badge is made.
How Fans Play With Project Hail Mary Characters Right Now #
Until a Project Hail Mary game arrives, fans who want more time with Rocky, or who want to design an Eridsona (the fandom’s name for a Project Hail Mary OC), have found their own ways to play.
| Option | What you get | What’s missing |
|---|---|---|
| Fanfiction on AO3 | 19,000+ works, including about 1,100 tagged Original Eridian Characters | You write both sides, so the characters never surprise you |
| AI roleplay platforms | Rocky or Grace replies in character (CAIBotList alone lists 500+ Ryland Grace bots) | No gameplay, only one-on-one chat with a single character |
| Project Hail Mary OC maker (Eridsona) | Design/Sketch your own character with Eridian OC ideas | Your character stops at a static image |
| Fan-made games on itch.io | Small indie projects like Hail Mary: Flight Simulator (pilot a ship from Earth to Tau Ceti) and Crazy Stupid Rocks (a comedy visual novel set on Erid) | Fixed characters and scripts, play as one character at a time and your Eridian OC can’t join |
Each option covers one piece, whether that’s the story, the design or a short interactive experience, but none of them gives your a world where Rocky, or your OC can actually play in. If you want to play with canon characters like Ryland Grace or Rocky, your Eridian OC, or explore alternate universes (AUs) that go beyond a chat thread, Redbean is where you can bring them to life: talk to them, play with them and live in your own PHM-inspired world.
How to Turn Project Hail Mary Rocky or Eridsona into Playable Characters in Redbean #
Redbean is a mobile life simulation-RPG sandbox, free-to-play on iOS and Android, built for OC/fandom creators and roleplayers, or anyone who loves to play with their favorite characters. Turn an image into a playable pixel character with a unique persona. Build and design your own town, create interactive storytelling and chat-based roleplaying experience with your own characters.
Here are 4 steps to build your own Erid, Tau Ceti, or any town, with Project Hail Mary Rocky, Grace and your OCs.
Step 1: Recreate Rocky as a Playable Character #
- Upload a picture of Project Hail Mary Rocky (your fan art or a screenshot) to make him a playable pixel character. Design him as he is: five limbs, a rocky carapace, no face or eyes, or your own version of Rocky
- Personality: loyal, curious, literal. Role: Eridian engineer.
- Speaking style: end questions with “, question” and repeat words for emphasis (“Amaze, amaze, amaze”). Chat is text, so his chords come through as cadence.
- Restyle him anytime with a new picture, a sketch or a short prompt.
Step 2: Create a Playable Eridian OC #
- Upload your drawing or a picture of your Project Hail Mary OC, and it becomes a character you can play.
- Eridian OC ideas: you can base the carapace and name on a real-world mineral, like the red malachite Eridian or crystal-heavy Eridian with a bright, multi-colored skin.
- Give them an unique name and a job on Erid: engineer, Eridian scientist, linguistic historian or xenonite sculptor.
- Set your OC as the main character or NPC, as Rocky’s newest crewmate or rival – any kind of relationship you define.
Step 3: Add Grace, Stratt and Adrian, or Give Grace a Rocky Companion #
- Recreate Ryland Grace, Eva Stratt and Adrian from pictures. They join your town as NPCs with their own personalities.
- Set free-form relationships, several per pair if you like: Grace and Rocky as best friends (“platonic soulmates” in fandom terms), Adrian as Rocky’s mate on Erid, Stratt as the mission lead.
- Want to play as Grace? Make him your main character and give him Rocky as a pet companion, created from a picture, so the two explore town side by side.
Step 4: Build a Town in Space, on Erid or on Any Planet #
- Design your town’s theme in a few words, like “Tau Ceti research colony” or “modern Eridian city,” or any concept you love.
- Make buildings and furniture from a photo, a sketch or a short description, such as a xenonite workshop or an astrophage lab.
- Build more than one town, every town feels different. Create your own Project Hail Mary AU or crossover with characters from different universe: The Martian, Iron Lung, other sci-fi movies or games like Cyberpunk.
- Publish a town so other players can visit and play in it. Or your Grace could explore other towns in Explore.
Project Hail Mary AU Ideas to Try #
Your Project Hail Mary AU can go anywhere your imagination does. For example:
- Third crewmate: a self-insert or x reader setup where your OC joins Grace and Rocky.
- Eridian exchange students: Grace teaching a class of young Eridians.
- Teacher or coffee shop AU: the whole cast relocated to a modern Earth town.
- BloodyMary crossover: recreate Simon from Markiplier’s Iron Lung and move him in next to Grace, the multiverse crack ship that took over the fandom in 2026.
Project Hail Mary Roleplay: Chat and Do Quests With Your Characters #
Turn your Hail Mary crew or Eridsona into a game you can play.
Talk in character, as your character. Play as your Eridian OC and chat with anyone in town about anything, the core of any Project Hail Mary roleplay. Rocky answers with the personality and speaking style as you wrote him to be, and what you say shapes relationship over time. Characters walk around town, remember what you tell them within the story, react to events and create stories on their own.
Write a scene, get quests. Describe a situation and Redbean turns it into quests for your characters, which gives your roleplay real scenarios to play through. A scene to try:
The astrophage samples in Grace’s lab are dimming. Rocky needs xenonite plates from his workshop across town before the launch briefing, and Eva Stratt wants a full report from the crew by sundown.
Stage encounters and let the crew live. Place Grace next to Rocky and they meet and talk on their own, which makes it easy to set up the moments you want to see. Between scenes, characters follow their own daily routines, so the town keeps moving while you play.
FAQ #
Who are Rocky and Adrian in Project Hail Mary? #
Rocky is an Eridian engineer from the planet Erid who meets Ryland Grace in the Tau Ceti system and becomes his closest friend. Adrian is Rocky’s mate back home on Erid. Grace picks “Adrian” as a human stand-in for the name Rocky sings in chords.
How does Rocky talk in Project Hail Mary? #
Rocky speaks in musical chords, and Grace builds software that translates them into English. That’s why his lines are short and literal, with questions ending in “question.” In the 2026 film, Rocky’s lead puppeteer, James Ortiz, also provides his voice.
Are there headcanons or shipping trends in Project Hail Mary? #
The biggest relationship in the fandom is platonic: Ryland Grace & Rocky has more than 6,000 works on AO3. The most popular crossover is Project Hail Mary × Iron Lung (“BloodyMary”), which ships Grace with Simon from Markiplier’s movie, has attracted thousands of fan works. Rocky and Adrian (Rocky’s mate in the original novel) is also the subject of several popular fan headcanons. Eridian OCs (Eridsonas) and canon characters round out the fandom’s favorite ships.
Can I play as Rocky or my own Eridian OC in Redbean? #
Yes. Create Rocky or your Project Hail Mary OC from a picture, set them as your own playable character, and start a Project Hail Mary roleplay scenario with the rest of the cast. You can play Rocky as a main character, or interact with him as your town residents, set connections with others and watch them
Redbean has no connection to the official Project Hail Mary game. It’s a playground where fans recreate their favorite Project Hail Mary characters and play with them.
Besides Project Hail Mary, can I create other characters in Redbean? #
Yes. You can turn any character you love into playable characters, from your own OCs to favorites from other games, anime and shows. Many players build multiverse towns where several fandoms share one map, like the crossovers in our Forsaken Roleplay Guide or The Walten Files. Check out Redbean’s Character Gallery for more character and OC inspirations.
Your Crew Doesn’t Have to Wait for a Project Hail Mary Game
The official Project Hail Mary game will give Grace’s side of the mission a new chapter once it launches. Your own Eridians doesn’t have to wait for it. Turn Rocky, Grace into playable characters and put your Eridsona on the crew, interact with them and live in a world you build.
