Rain World

Safari Mode for the Watcher campaign launched, opening its regions and creatures to Safari Mode runs and adding Ripple Trees throughout the campaign. The rollout also delivered a visual overhaul for ripple spawns, rebalanced ripple jellies, and adjusted karma flowers around ripple spawn eggs.

• Watcher content: Safari Mode covered the Watcher campaign’s regions and creatures, while Competitive arena mode received more varied Watcher creature spawns. Players who had already completed the Sentient Rot ending also retroactively unlocked the rotted Watcher safari regions.
• Creature and world systems: Ripple spawn pathing improved, and Sky Whales, Frogs, Rats, and multiple frogs attached to larger creatures more reliably. Creature interactions also became more varied, with improved slope collisions, shelled Barnacle avoidance, Weaver Threads visibility, and positioning for Lobe Trees and Bone Shakers.
• Balance and progression: Basilisk Lizards and Blizzard Lizards were nerfed, Yellow Lizard packs stopped treating dead pack members as active, and Loach diets changed. Hunter’s campaign retained Pebbles’ extra cycles correctly, while Artificer’s ending, Watcher’s final ending, Spinning Top’s older-save trigger, and The Prince’s Jolly Co-op dialogue received progression fixes.
• Watcher reliability: The Watcher rollout corrected crashes involving Adult Sand Grubs, Drill Crabs, warp-point creation, Shattered Terrace, PlayStation 4 save loading, Ripple Spiders, and echo encounters with Rain World Remix disabled. It also fixed corrupted warp maps, inaccessible Slugpup shelters, Inv’s campaign music triggers, and several Watcher ending and attunement conditions.
• Soundtrack and modding: Three previously Bandcamp-exclusive Rain World OSTs reached Steam. Region modders received faster room baking, Steam Workshop uploads stopped failing after repeated updates, and Watcher music triggers received repetition and frequency adjustments.

Rain World: The Watcher launched on PC on March 28, 2025, adding a new campaign and a major new layer of exploration to the slugcat survival game. The September 2025 update expanded that content with multiplayer, Arena support, new regions, creatures, items, and endings, while The Watcher Level Editor opened custom-level creation to modders.

• The Watcher campaign: The September update added new endings, regions, creatures, items, and Arena unlockables to The Watcher’s campaign.

Warp markers appeared on region and hibernation maps, the forced one-way route in Cold Storage was removed, and warp points improved key-item retrieval.
• Modding tools: The Watcher Level Editor launched in November, giving modders a dedicated tool for building custom levels. BepInEx 64-bit support also improved code-mod loading, while new Workshop compatibility tags clarified which game and DLC components mods supported.
• Creature and campaign tuning: Barnacles, Locusts, Moths, and Watcher-campaign lizards received behavior changes, while Basilisk Lizards stopped applying effects while unconscious. Saint also received a stun-duration adjustment, and shelter encounters became slightly more forgiving when aggressive creatures were present.
• Technical support: The December 2025 update addressed major memory leaks and crash causes, particularly on Nintendo Switch, while the February 2026 update fixed additional The Watcher crashes, including failures involving adult sandgrubs, the statistics screen, electric cycle deaths, and Jolly Co-op.

Rain World: The Watcher was announced as the next DLC expansion, with its March 28 release date revealed. The April 1 update removed the high-death-rate Slugcat character and fixed a major Mother Long Legs crash, while Rain World Art Month brought daily community prompts in March 2025.

March 18, 2024 update was the window’s main beat: a broad maintenance pass centered on Safari and Remix. It fixed crashes, soft locks, mod-ordering problems, and controller configuration issues, but the tracked changes did not add a new campaign, region, mode, or other major content.

• Campaign and stability: Artificer, Safari, and several campaign-specific edge cases received the most consequential fixes.
  • Artificer: Dream-sequence crashes stopped.
  • Safari: Scavengers no longer performed random actions, and creature transports no longer soft-locked players by entering inaccessible areas or mismatched time periods.
