However, some mods have not yet been updated, and they will not work in 1.6. ##### Odyssey original soundtrack You can also grab the **[RimWorld - Odyssey soundtrack](https://store.steampowered.com/app/3689230/RimWorld__Odyssey_Soundtrack/ )** on Steam. Created by RimWorld composer Alistair Lindsay, it features 10 thrilling, spacey tracks to accompany you during your orbital expeditions. ##### Odyssey merch collection We’ve just launched our new, limited-edition **Odyssey collection** on our official merch site: **[https://rimworld.store/](https://rimworld.store/)** The collection includes: - **RimWorld bomber jacket and patches**: A stylish colonist jacket with iron-on patches so you can proudly display your favorite expansions. - **Centipede plush**: For such a heavily-armored murder machine, it’s very plump. - **Odyssey T-shirt**: This gravship tee is perfect for launching into the stars, digging through ruins, or fighting off pirates. - **Hive queen plush**: All the terror of the insectoid matriarch, bloated with cuteness instead of larvae. ##### Odyssey Odyssey enriches the world and expands your adventure beyond a single map. Build a gravship - your flying home - to travel across the planet. Settle in new biomes filled with diverse landforms and exotic wildlife. Go on quests to hunt the alpha thrumbo or raid ancient cryptosleep bunkers. Launch into orbit and scavenge tech from space stations and asteroids. But out in the void, an ancient machine mind stirs… Tell us about your gravship adventures over on Reddit, X, and BlueSky. Found a bug? Please report it in the [RimWorld official development Discord](https://discord.gg/MC6eYAHuPu). Odyssey is available to play in: English, Chinese Simplified, Chinese Traditional, Russian, French, German, European Spanish, Latin Spanish, Brazilian Portuguese, Japanese, Korean, Polish, Turkish, Ukrainian, and Dutch.
