The primary upgrade currency for every suit enhancement. Found in hidden alcoves, behind waterfalls, atop cliff ledges, and inside Stomped floor panels. Some deposits require Grapple or Double Jump to reach. Collecting all Goo across all four planets gives you more than enough for the entire upgrade tree — with leftover.

Your in-game encyclopaedia of alien life. Scan every creature and plant you encounter to build the complete Kindex. Some entries have specific scan conditions — bosses must be scanned during the fight, certain creatures only appear under environmental conditions, and a few require special approach methods to trigger the scan window.

Hidden chambers concealed behind Stomped floor panels, breakable walls, and waterfall curtains. Each contains a significant Orange Goo cache, a unique Kindex entry, or both. Every planet has at least two secret rooms. The most valuable single Goo deposits in the game are inside secret rooms — including a 25-Goo cache on both Stellaris Prime and Noxious Ridge.

Four terminal-based lore logs scattered across the planets in order of the story. Reading all four reveals what Kindred Technologies was actually doing in this sector of space — the central mystery of the game. Each log is on a specific terminal in a specific sector. Log 4 on Noxious Ridge is the final story beat before the Apex Predator fight.

Your personal Space Trailer accumulates decorations, trophies, and creature companions throughout the game. Filling all pen slots, building all structures, and placing all decoration items contributes to the habitat completion objective. Creature pens also generate passive Goo income — building them early compounds over a full playthrough.

Seasonal event rewards obtainable only during active Bingo Brawl windows. Completing bingo cards unlocks exclusive cosmetics and two event-specific achievements.
