RocketWerkz pushed Icarus Week 211 live on Steam. The patch introduces a new enemy type, a short holiday XP boost, and a new world setting to turn spiders off if you prefer to avoid them.
What to play for this week
There is a limited double XP event running alongside a steep Steam winter sale that discounts Icarus up to 90 percent. DLC packs are also reduced for players who want to pick up expansions or item bundles.
This week: Spiders

The update adds a new creature class: **spiders**. They are nocturnal, appear outside caves in Forest and Grassland biomes across Olympus, Styx, and Prometheus, and use poisonous webs that slow movement. Defeating them yields a new resource, Spider Silk, which unlocks alternate recipes for Rope, Platinum Weave and other items. Spiders also have a craftable trophy and a bestiary entry.
This week: Arachnophobia Mode

For players who want to avoid eight-legged encounters, the update adds **Arachnophobia Mode** to the Custom World Settings menu. Hosts and admins can toggle spider spawning on or off when creating a new Prospect (Difficulty section) or from the Escape menu during a Prospect. New Prospects default to Arachnophobia Off; existing Prospects default to On so spiders do not suddenly appear in established worlds.
Next week: Rideable woolly mammoths

RocketWerkz also previewed a tameable, rideable woolly mammoth arriving next week. Juvenile mammoths will spawn with parents, can be captured and tamed, and will include their own talent tree and saddle items.
Small fixes
- Fixed being unable to pick up pieces of Cake after the session is reloaded.
- Adjusted mount spawn locations when bringing mounts down from orbit so they appear in more navigable terrain near the pod.
