Crossover Collab

Crossover Collab is a big Celeste mod where each map has at least the size of a vanilla map, featuring:

• 20+ maps (+extras) spread across a wide range of difficulties

• 1000+ playable rooms

• Hundreds of custom entities and cutscenes

• 200+ collectables

Madeline sets off to play videogames in her own computer.

Crossover Collab was made with the help of 100+ people over the span of three years, with big contributions from ~40 members. Discover new games and rediscover games you already played from a Celeste perspective. Explore over a hundred hand-crafted environments. Face challenges from casual platforming to mind-melting puzzles.

Crossover Collab is divided into 5 difficulties within a single lobby from which you can access its maps. Each map teaches you all the new mechanics you'll need to use, with descriptions or playbacks. The two hardest maps come with their own gyms, showcasing the techs required in them.

Thank you to everyone involved in this enormous project, and we hope you enjoy it!

FAQ

• Do I need to own Celeste in order to play this?

• Yes. Crossover Collab is an add-on fan-made mod for Celeste, not a standalone product. Note that mods do not work for Microsoft Store copies of the game!

• Can I play this on my Switch or other console?

• Unfortunately,

no. Crossover Collab requires the Everest mod loader, which is desktop only. However, it is playable on the Steam Deck, in desktop mode.

• Is there any additional content?

• Feel free to replay maps that you enjoyed after you clear them for the first time. Who knows? Maybe you will discover something new!

• Certain files in BerryOS (Madeline's computer) are unlocked under certain conditions.

• **I

feel it will be too difficult for me. Can I still experience the visuals and music of the harder levels without grinding them for dozens of hours?**

• Yes. Celeste’s

Assist Options are compatible with Crossover Collab, so you can adjust the difficulty to suit your preferences. While it is recommended to have completed at least the main story of Celeste, you can directly dive in the easiest maps.

• Most of the

maps expect you to be familiar with several techs, especially at middle-high difficulties, but all new mechanics are taught.

• If you need additional info about generic movement and techs, you can visit the Gyms in Strawberry Jam/Spring Collab/other mods.

• I’ve already played Strawberry Jam, will the difficulty scale be the same?

• While

the general difficulty categories of Crossover Collab are similar to Strawberry Jam, the maps may not follow the exact same difficulty boundaries as you’re used to. Certain optional secrets may be more than one star above the rest of the difficulty of the map.

• So many games! Where should I start?

• Every map has colored stars that correspond to its difficulty (map completion with all main collectables, excluding secrets), from half star (easiest map) to beyond 5 stars

(hardest map). These stars are found on the title banners in the Map Launchers. If you're new to a certain difficulty or modding in general, we recommend trying out maps marked green on their meters first for a smoother experience.

• Help! The installation process didn’t work/my game crashed/I’m having other technical difficulties:

• If

you’re having trouble installing Everest or Crossover Collab, please double-check the installation instructions and make sure you didn’t skip a step or download the wrong version of Everest for your system.

• If

you’re getting the in-game error “Mods failed to load”, please navigate to the Mod Options menu and select “install missing dependencies”.

• If

your game crashes, an error log will pop up. Try disabling all mods besides Crossover Collab, its dependencies, and any cosmetic or quality of life mods you would like to use.

• If the problem persists after trying these steps, join the official Celeste Discord server and post the issue in the #modding_help channel. If the issue is specific to the mod, you can also ask in the Crossover Collab Community server.
