Gorilla Nebula is Astro Bot's opening world, introducing the game's core mechanics across six main planets plus a bonus challenge stage. Each planet is a compact 3D platformer level built around one or two of Astro's gadgets — the basic Bop Gloves, water squirt gun, and Ground Pound are all introduced here. Rescue every bot you see, as saved bots populate your Crash Site hub and many unlock secret levels. The Gorilla Nebula finale boss is Mighty Chewy, a giant mechanical gorilla; collect any remaining puzzle pieces from earlier planets before the boss stage since the hub reveals which planets are incomplete. Puzzle pieces are used to repair the PS5 spaceship at the hub.
The Tentacle System introduces the Water Gun and Sponge gadgets in earnest across its six planets. The sponge levels require you to soak up water and squeeze it out to solve environmental puzzles and stun ink-covered enemies — look for blue-outlined surfaces that indicate absorbable moisture. The Tentacle System contains two of the game's best hidden bot locations tied to the “Lost Galaxy” secret exits, which appear as broken rocket ships in the stage environment that Astro can kick off to launch. Fire the Bop Gloves at the neon signs in the cyber-themed Tentacle System levels to reveal hidden platforms.
Serpent Starway introduces the grappling hook gadget, which allows Astro to swing across large gaps and pull enemies toward him for combo finishers. Several Serpent Starway planets are themed around ancient ruins and jungle environments; use the grappling hook to strip shields from snake-type enemies before punching. The Serpent Starway is home to the highest density of PlayStation cameo bots — recognizable characters from God of War, Horizon, and Spider-Man are hidden in alcoves throughout these levels. Lady Venomara is the galaxy boss; bring maximum health upgrades found by feeding the fish at the Crash Site before entering the boss stage.
Camo Cosmos is the fourth galaxy and introduces the Chameleon Suit, which lets Astro temporarily become invisible to bypass enemies or sneak past environmental sensors. Stealth sections are immediately followed by gadget-action sections that strip away the suit and test combat skills — the pacing makes Camo Cosmos one of the most varied galaxies in the game. The galaxy's challenge stages are significantly harder than earlier ones and feature strict time limits; complete the main planets first to build familiarity with the Chameleon Suit before attempting them. Galaxy boss Mecha Leon is a mechanical lion; bring full health going in and do not skip collecting the puzzle pieces from the Camo Cosmos ruins planets as they are needed for the spaceship repair.
Feather Cluster is the fifth and most technically demanding main galaxy, built around the Fan gadget, which generates gusts of wind Astro can ride to reach high platforms and carry objects to switches. Wind physics in these levels interact with environmental elements like seeds, balloons, and lightweight enemies in ways unique to each planet — take a moment to observe how the wind flows before committing to a path. Feather Cluster contains the game's longest individual platforming sequence, a multi-stage airship level that unfolds continuously without checkpoints; stock up on health orbs at the Crash Site before entering it. Boss Falcon McFly caps the galaxy.
The Crash Site is the central hub where all rescued bots gather and puzzle pieces are used to progressively restore the wrecked PS5 ship. Ten Lost Galaxy secret levels are accessed via hidden portals in the main five galaxies — each lost galaxy contains a unique themed level that often references a specific PlayStation franchise in detail. Lost Galaxy levels contain some of the game's best-hidden bots and the most elaborate gadget puzzles; the Astro Bot development team level is particularly memorable and contains multiple developer references. Completing all Lost Galaxies and rescuing every bot is required for the Platinum trophy.
After clearing all five main galaxies, the final area of the Crash Site unlocks: a gauntlet of remixed platforming challenges followed by the final boss Space Bully Nebulax. Before pressing the red button to trigger Nebulax, ensure all 300 bots are rescued and all 120 puzzle pieces are collected — the post-game free-roam still allows completion but the boss area locks off until Nebulax is defeated. The Nebulax fight has three phases, each requiring a different gadget drawn from a spinning wheel; familiarize yourself with the Monkey Gloves, Frog Spring, and Magnet Gloves from earlier planets as you will need to use all three during the fight.
⚔️ Boss Guides
Mighty Chewy (Gorilla Nebula Boss)
Attack Patterns
Mighty Chewy is a giant mechanical gorilla who opens by slamming his fists on the circular platform, generating shockwaves that roll outward from each impact point. He rears up and tosses bananas into the air that fall in arc patterns onto the platform. At 66% and 33% health he changes the platform shape and adds a bell-slam attack that rings a stadium bell above the arena, crashing a weight down on the center. His third phase adds a full platform floor-chomp attack where he bites the arena edge.
Strategy
The core loop is punch the falling bananas back at his face using the Bop Gloves — each banana hit stuns him briefly and exposes a glowing weak point on his body. Hit three exposed weak points (his eyes, then his chest, then his gaping mouth when he roars) to complete one damage cycle. During the bell-slam phase, position near the arena edge to avoid the central weight drop. For the floor-chomp attack, jump when you see his jaw lower at the arena perimeter. Three full banana-return damage cycles defeat him; the final hit triggers a cinematic stomp animation. Never stand directly under a falling banana — the explosion radius is larger than it appears.
Wako Tako (Tentacle System Boss)
Attack Patterns
Wako Tako is a giant mechanical squid who fights from the center of a circular ink-covered platform. He launches ink blobs that create slippery patches on the arena floor, coats his eyes with ink to become temporarily invulnerable, and slams his tentacles in patterns across the arena in sequences of three — left, right, then center. In phase two he submerges briefly and launches an ink geyser that covers half the platform simultaneously. His final phase adds homing ink missiles that require two direction changes to dodge.
Strategy
Immediately spray his ink-covered eyes with the Water Gun whenever they turn black — this strips the ink coating and stuns him, exposing a damage window. During the tentacle slam sequences, stay near the platform center and jump over the left and right slams, then dodge backward for the center slam. For the phase two ink geyser, sprint to the dry side of the platform the moment he submerges. After completing three eye-wash stun cycles, a glowing plug appears on the top of his head — approach and pull it with the interaction prompt to deal the finishing blow. Keep the Water Gun aimed at his eye level throughout — dropping the angle causes missed shots and wastes the stun window.
Lady Venomara (Serpent Starway Boss)
Attack Patterns
Lady Venomara is a giant mechanical serpent who slithers continuously around a circular arena while spitting venom projectiles in arc patterns. Her venom pools linger on the arena floor for several seconds and deal damage on contact. She rears up on her tail periodically with her mouth open wide — this is the grapple window. In phase two she adds a body slam that sweeps the entire arena width, requiring a jump timed to the telegraph. Her final phase introduces homing venom missiles that track for two seconds before detonating.
Strategy
Watch for the rearing animation — Venomara freezes briefly before rising, giving you time to aim the grappling hook at her exposed fangs. Each successful fang pull yanks a fang loose, knocks her to the floor, and opens a brief close-range attack window where the Bop Gloves deal bonus damage. Three fang pulls are needed across the three phases. During her slithering venom phase, move laterally around the arena edge rather than cutting through the center, as the venom pools cluster toward the middle. For the body slam, jump at the moment her body begins descending — jumping too early means she catches Astro on the apex of the swing. In the homing missile phase, sprint in a tight circle; the missiles detonate when they lose Astro's direction for more than two seconds.
Mecha Leon (Camo Cosmos Boss)
Attack Patterns
Mecha Leon is a giant mechanical lion who patrols the boss arena aggressively. He uses a three-claw horizontal sweep attack that covers roughly 270 degrees around him, a pounce that crosses the arena quickly, and a ground-shaking roar that creates a shockwave requiring a jump. His head-sweeping vision cone rotates continuously and triggers an alarm phase if Astro is spotted outside the Chameleon Suit, which causes him to begin his pounce chain.
Strategy
Use the Chameleon Suit to approach from his blind spot — directly behind his tail during the patrol. A hidden attack from behind the suit deals double damage and staggers him immediately, opening a Bop Gloves combo window. After the stagger, strike his glowing chest jewel five times with the Gloves before he recovers. In phases two and three he patrols faster and the vision cone sweeps more frequently; use short bursts of the suit to reposition rather than staying invisible continuously (the suit has a limited duration battery). Dodge the claw sweep by sprinting behind him, then wait for the roar animation to jump over the shockwave and follow up with the Gloves.
Falcon McFly (Feather Cluster Boss)
Attack Patterns
Falcon McFly is a mechanical bird who fights from the air using dive bomb attacks, wind vortex throws that pull Astro toward his talons, and feather barrages fired in fan patterns across the platform. He briefly lands on the platform edge after every third attack cycle, folding his wings before launching another aerial assault. His phase two adds a sonic screech that temporarily disables the Fan gadget for five seconds.
Strategy
Aim the Fan gadget directly at his chest during his dive bomb approach — a sustained blast reverses his trajectory and interrupts the attack, sending him skidding along the platform briefly. During the grounded landing phase, sprint in and use the Bop Gloves on his exposed chest while he recovers from the Fan blast knockback. Three ground-phase Glove combos constitute one full damage cycle. For the wind vortex, boost the Fan perpendicular to the pull direction rather than directly against it — fighting the vortex head-on drains the gadget faster. During the sonic screech phase, retreat to the platform center and wait out the five-second gadget disable before re-engaging; the screech itself does no damage if Astro is outside mid-range.
Space Bully Nebulax (Final Boss)
Attack Patterns
Space Bully Nebulax is the game's final boss and the bully who shattered Astro's PS5 ship. He fights from a giant mechanical suit and cycles through three phases, each unlocked when a random gadget is drawn from a spinning wheel at the phase start. The gadget determines both the attack pattern Nebulax uses and the tool Astro must employ to counter it. Nebulax's attacks include fist slams, laser eye sweeps, suction beam pulls, a pinball ricochet with spiked balls, and a full-arena ink bomb in the final phase.
Strategy
The key insight for Nebulax is that the “random” wheel always gives you the gadget that counters his current phase attack — there is no random disadvantage. During the Monkey Gloves phase, he telegraphs his fist slam with a long windup; grapple the fist after it lands to rip out a weak component. During the Magnet phase, he fires metal debris — use the Magnet Gloves to catch and redirect it back at his torso panels. During the Frog Spring phase, his arena fills with floor spikes that the Spring jump clears while allowing aerial attacks on his crown sensor. Strike the glowing orange weak point revealed after each successful counter three times per phase to complete the damage cycle. The final phase requires using the gadget from the spin wheel under time pressure while avoiding the ink bomb blast radius; position near the arena center throughout the final phase to maximize reaction time in all directions.
