Everything is Crab: the evolution roguelite where everything wants to become a crab
Picture an ecosystem where you start as a tiny blue blob and, over a single ~20-minute run, mutate into a horrifying apex predator. Everything is Crab: The Animal Evolution Roguelite by Odd Dreams Digital (published by Secret Mode) plays on a real biological phenomenon — carcinisation, where wildly different creatures keep evolving toward a crab-like shape. Here you decide what to mutate into and build a unique creature every time. On this page you buy the full game as a Steam gift that we send straight to your account.
What kind of game it is
It's an action roguelite with strategy, simulation and RPG elements. The game launched on May 8, 2026 and quickly earned warm reviews — around 87% positive across thousands of ratings. The loop is built on short runs: you survive, eat, grow and pick a new evolutionary trait at every step. Runs are short, but replayability is huge thanks to the sheer number of combinations.
How a run works
Each round is a tiny life of your creature. You hunt some animals and flee from others, gain mass, mutate and gradually change both your mechanics and your look. Procedurally generated bosses wait at the end. Between runs there's meta-progression: difficulty levels, genetic starting characters, separate challenges and endless runs for players who want to push a build to its limit.
125+ evolutions and specialisations
The headline feature is over 125 evolutions and specialisations you mix into your own beast. Go down the crab path if you like, or pick alternative branches and build something truly wild. Every run feels different: some builds are about aggression and damage, others about cunning, defence and mobility. That variety is exactly why people keep coming back.
Four biomes and a living ecosystem
The map isn't scenery — it's a living world. There's a day-and-night cycle and four distinct biomes with their own rules, climate events, flora and fauna, from deserts to frozen tundras. Other creatures don't just stand around: they hunt each other, dash across the map, and some disguise themselves as fruit to fool you. You're only one part of this breathing ecosystem, and that keeps you on edge.
What's included in the Steam gift
You get the full base game Everything is Crab: The Animal Evolution Roguelite. It's not a demo and not an add-on. The separate Supporter Pack is a standalone DLC and is not part of this gift: if you want to back the developers with the bonus set, it's bought separately. Once redeemed, the game stays on your Steam account for good.
How we deliver the gift
Delivery goes through Steam Gift. You provide your friend invite link and your account region, place the order, and our bot adds itself to your friends and sends the gift. You don't need to accept the friend request manually, and after delivery the bot removes itself automatically. Steam Guard is not required to receive the gift. It usually arrives within a couple of minutes of ordering.
Account region and library
Two conditions, without which Steam won't let you accept the gift. First: your Steam account region must match the gift region — pick the option for your region on the page. Second: Everything is Crab must not already be in that account's library, otherwise Steam simply won't accept the gift. If both are met and your profile accepts friend requests, delivery goes through smoothly.
System requirements and platforms
The game targets PC on Windows 10 and newer. Mac and Linux aren't officially listed by the developer, so on Steam Deck and Linux it only runs through the Proton compatibility layer — outside the studio's guarantees. The game is translated into many languages, including Russian, so the interface won't be a barrier.
Similar games
If you enjoy short runs, build crafting and "just one more before bed," check out other roguelites and survivors in our catalog: Vampire Survivors, Brotato and Risk of Rain 2. Same genre — randomized builds and high replayability — but each game twists the formula its own way.
Buying in short
Everything is Crab is a complete, already-released evolution roguelite that you receive as a Steam gift. The keys at checkout: the right invite link, a region that matches the gift, and a library that doesn't already include this game. The bot handles the rest.
