How to get to the fifth planet in Revenge of the Savage Planet

Complete walkthrough for unlocking Slappi’s Den of Fun and conquering the hidden fifth planet in Revenge of the Savage Planet

Introduction to the Hidden Fifth Planet

Revenge of the Savage Planet conceals an entire additional world that becomes accessible during the late-game progression. This secret destination, known as Slappi’s Den of Fun, represents one of the game’s most rewarding hidden features. Unlocking this content requires methodical progression through specific story elements and careful collection of essential items.

To gain access, players must first complete the Interstellar Enigma storyline quest, which serves as the gateway to the Pentaforce collection process. The Pentaforce consists of five distinct fragments scattered across different planetary locations, each protected by unique shrine challenges. Successfully gathering all components transforms your gameplay options significantly.

Pro Tip: Begin your Pentaforce hunt only after reaching character level 25+ and upgrading your primary weapons to tier 3. The shrine challenges demand substantial combat proficiency and mobility skills that early-game characters typically lack.

Locating All Five Pentaforce Shrines

The Pentaforce collection represents the most extensive side quest in Revenge of the Savage Planet, requiring traversal across multiple planetary systems. Each shrine presents unique environmental challenges and combat scenarios that test different player skills.

• Shrine of Timing – Positioned west of Habitat Base on Stellaris Prime, this shrine sits atop a steep hill enclosed by formidable cliff faces. The challenge emphasizes platforming precision and requires mastery of the double-jump mechanic. Strategy: Equip mobility-enhancing gear before attempting this shrine.
• Shrine of Pressure – Located within the treacherous Cliffs of Abaddon region on Stellaris Prime, this trial focuses on combat under environmental constraints. Players face continuous damage zones while battling enemies. Common Mistake: Rushing through without proper healing items.
• Shrine of Grind – Found adjacent to Cactus Pools on Xephyr, this challenge tests endurance through wave-based enemy encounters. The key is resource management and strategic positioning. Optimization: Use area-of-effect weapons for crowd control.
• Shrine of Combat – Submerged within Bilodeau’s Floating Isle in the Zenithian Rift, this underwater shrine demands aquatic combat proficiency. Enemies here exploit the three-dimensional battle space aggressively. Preparation: Upgrade oxygen capacity and underwater mobility.
• Shrine of Challenge – Unlocks sequentially after conquering the previous four shrines. This culminates in a demanding boss confrontation against the Cyber Wardrill, requiring mastery of all previously tested skills. Warning: This fight cannot be retreated from once initiated.

Navigation Strategy: Complete shrines in order of increasing difficulty—start with Shrine of Timing, progress to Pressure, then Grind, followed by Combat, saving Challenge for last. This progression builds necessary skills gradually.

Unlocking and Accessing Slappi’s Den

After successfully gathering all Pentaforce fragments, return immediately to your central operations hub known as The Habitat. Here, the research computer interface will recognize your achievement and present a new specialized research option specifically related to the Pentaforce.

Activating this research perk fundamentally alters your travel capabilities within the game universe. The interface transforms, revealing Slappi’s Den of Fun as a selectable destination. This represents a permanent unlock that remains available throughout your playthrough.

The Planet Cannon serves as your transportation method to this hidden world. This massive device requires precise interaction—approach the control panel and initiate the launch sequence. Critical Note: The Planet Cannon journey includes an unskippable cinematic sequence, so ensure you have adequate time allocated before departure.

Advanced Tip: Before launching, visit merchants to stock up on healing items and ammunition. Slappi’s Den contains limited resources, and the rail cart sequence prevents returning until completion.

Conquering the Rail Cart Challenge

Upon arrival at Slappi’s hidden world, your character automatically boards an elaborate rail cart system that transports you through the planet’s interior. This sequence combines narrative exposition from Slappi himself with interactive environmental puzzle-solving.

The rail cart progression features multiple security doors that block forward movement. Each barrier is controlled by distinctive purple terminal panels positioned adjacent to the doors. These terminals emit a subtle glow and distinctive audio cue when approachable.

Terminal Engagement Strategy: Aim precisely at the center of each purple terminal and fire immediately when within range. The terminals require only a single hit to activate, but timing becomes crucial as the rail cart maintains constant motion. Pro Technique: Pre-aim at upcoming terminals while dealing with the current one to maintain momentum.

Common Pitfall: Players often waste ammunition by shooting terminals too early or too late. The effective range is approximately 10-15 meters—wait for the terminal to fill your crosshairs before firing. Missing shots doesn’t cause failure but significantly slows progression.

Mecha Slappi Boss Battle Strategy

The climactic chamber houses your confrontation with Mecha Slappi, where the titular character pilots a massive robotic combat frame. This multi-phase boss battle demands adaptive tactics and pattern recognition.

Mecha Slappi employs three primary attack patterns: rapid-fire projectile volleys, ground-slam area attacks, and charging maneuvers. Each phase introduces additional attack variations and increased aggression. The key to victory lies in identifying visual cues that telegraph each attack type.

Weakness Exploitation: The cockpit area where Slappi resides represents the critical vulnerability. During attack animations, the cockpit shield retracts briefly, creating damage windows. Optimal Strategy: Conserve high-damage weapons for these brief exposure periods rather than wasting ammunition on armored sections.

Victory against Mecha Slappi triggers one of Revenge of the Savage Planet’s conclusion sequences and automatically grants the ‘Entertained to Death’ achievement. Additionally, your hub area permanently gains the Slappi toy collectible, which provides unique dialogue options and minor gameplay benefits.

Post-Victory Analysis: The Slappi toy in your hub serves as both a trophy and functional item, offering humorous interactions and occasionally providing crafting materials. Revisiting Slappi’s Den after completion reveals additional hidden areas previously inaccessible during the initial rail cart sequence.
