Obsidian Entertainment and Eidos-Montréal released patch 0.5.1 for Grounded 2 on September 24, 2026. The most substantial change in this update is the complete removal of Infused Ooze from the game, a decision that shifts the progression path for late-game equipment.
Grounded 2 is published by Xbox Game Studios and was developed by Obsidian in collaboration with Eidos-Montréal. This update follows previous iterations like patch 0.4.0. Players can find the full developer notes on the Obsidian Entertainment website.
Removal of Infused Ooze and Recipe Changes
The removal of Infused Ooze directly impacts high-tier crafting. Previously a required resource, its absence has necessitated a rebalancing of recipes. Specifically, the Tier 4 Omni-Axe recipe was updated to reflect the removal of Infused Ooze, ensuring players can still craft the tool without the discontinued material.
Expanded Molar Upgrades
Patch 0.5.1 introduces additional progression tiers for players collecting Milk Molars. These new tiers apply to several categories of permanent upgrades:
- Mega Milk Molars: New tiers added for group-wide stat increases.
- Milk Molars: Additional tiers for individual character buffs.
- Moldy Milk Molars: Expanded tiers for specialized upgrades.
AI Improvements and Combat Balance
Combat dynamics have been adjusted through a buff to Buggy perception. This change allows companion Buggies to join fights more easily alongside the player. This adjustment is intended to make AI allies more responsive during encounters.
Fixes and Quality of Life Updates
The update addresses several technical issues and cross-platform inconsistencies identified following the PlayStation 5 launch.
- Crossplay Visibility: PlayStation 5 players can now correctly see the online status of Steam players.
- Creative Mode: The requirement to wear a Diving Suit to open the Abyss hatch has been removed for players in Creative mode.
