Introduction to Descent Protocol
Descent Protocol is an intense underground platformer that combines drilling mechanics with fast-paced action. As an extraction specialist, you must navigate through the planet's volatile layers, dodging hazards, collecting resources, and fighting your way to the green EXIT elevator at the bottom of each level.
The game features a unique descending level structure where you move progressively deeper into the planet's core, encountering increasingly dangerous environments filled with lava pits, hostile drones, and unstable debris. Whether you're speedrunning to the exit or methodically collecting every crystal, this guide will help you master the mechanics and survive your descent.

Game Mechanics Explained
Movement and Momentum
Your character responds to physics-based movement:
- Acceleration builds as you hold a direction, reaching maximum speed quickly
- Momentum carries you briefly when changing directions
- Jumping maintains horizontal velocity, allowing for long-distance leaps
- Double-jumping provides a mid-air course correction
Movement Tip: Use short taps for precise positioning near ledges, and hold for maximum speed when crossing long platforms or running from hazards.
Platforms and Terrain
The underground environment features various platform types:
Standard Platforms (Brown):
- Solid surfaces you can walk on and jump from
- Form the basic structure of each level
- Safe to stand on indefinitely
Conveyor Belts (Gray with Arrows):
- Push you in the direction of the arrows
- Can help you gain speed or hinder your movement
- Useful for crossing gaps when used correctly
- Can push you into hazards if you're not careful
Breakable Blocks (Cracked Appearance):
- Shatter when you jump on them from above
- Can be broken from below by jumping into them
- Breaking blocks awards bonus points
- May hide collectibles or provide shortcuts
- Use strategically to open new paths
Vents and Boost Jumps
Yellow vent platforms provide powerful vertical boosts:
- Landing on a vent launches you upward automatically
- Reach high platforms and secret areas
- Escape from tight situations quickly
- Maintain horizontal control while being boosted
- Can chain multiple vents for extreme mobility
Advanced Technique: You can control your horizontal movement while being launched by a vent, allowing you to aim your boost toward distant platforms or collectibles.
Falling Debris
The unstable environment creates constant danger from above:
- Red rocks fall from the ceiling at random intervals
- Debris follows a predictable downward trajectory
- Getting hit deals damage and knocks you back
- Watch for visual cues or shadows indicating falling objects
- Some debris falls in response to your proximity (trigger zones)
Hazards and Enemies
Lava Pits
Perhaps the most dangerous hazard in Corefall:
⚠️ Critical Danger: Falling into lava results in instant death! The bright orange glow makes lava pits easy to spot, but their placement often creates challenging platforming sections. Always ensure you have a safe landing before jumping.
Hostile Drones
Automated security drones patrol the underground facility:
- Float along preset horizontal paths
- Deal damage on contact
- Cannot be destroyed - must be avoided or jumped over
- Pattern recognition is key to timing safe passages
- Some drones move faster than others
- Look for gaps in patrol patterns to slip through
Drone Avoidance Techniques:
- Observe the drone's movement pattern before approaching
- Time your approach for when the drone is moving away
- Jump over drones when they're at the far end of their patrol
- Use platforms above or below the drone's patrol path when possible
Collectibles and Resources
Energy Crystals
Blue glowing crystals are the primary collectible:
- Value: +100 points each
- Scattered throughout levels, often in challenging locations
- Some require precise platforming or risk-taking to obtain
- Collecting all crystals in a level awards bonus points
- Not required to progress, but boost your score significantly
Risk vs. Reward: Not every crystal is worth the danger. Evaluate whether the points justify the risk, especially if you're low on health or facing multiple hazards.
Health Pickups
Red heart icons restore your vitality:
- Restore health when collected
- Strategically placed near dangerous sections
- Spawn at fixed locations in each level
- Prioritize these when your health is low
- Sometimes hidden behind breakable blocks
Health and Lives System
Managing your health is crucial for survival:
Health Bar
- Displayed in the top-left corner of the screen
- You start each level with full health
- Taking damage from enemies, debris, or hazards depletes health
- When health reaches zero, you lose a life
Invincibility Frames
After taking damage, you gain brief invulnerability:
- Your character flashes to indicate invincibility
- Lasts approximately 1-2 seconds
- Use this time to escape dangerous situations
- Does NOT protect against lava - instant death hazards still apply
Strategic Use: When you take damage in a drone-heavy area, use your invincibility frames to push through rather than retreating. You can pass through multiple drones safely during this period.
Scoring System
Your performance is tracked through multiple scoring metrics:
- Energy Crystals: +100 points each
- Breaking Blocks: Bonus points per block destroyed
- Time Bonus: Faster completion times may award additional points
- Health Retention: Finishing with high health may provide bonuses
- Reaching the Exit: Level completion bonus
Your score is displayed prominently throughout gameplay, and your best scores are saved locally for future reference.
Level Structure and Objective
Descending Design
Corefall features a vertical level design where you descend deeper with each stage:
- Levels are structured vertically, requiring downward progression
- Multiple paths often lead to the same destination
- Upper routes may be safer but have fewer collectibles
- Lower routes are riskier but often more rewarding
The EXIT Elevator
Your objective in each level is to reach the green EXIT elevator platform:
- Located at the bottom of each level
- Clearly marked with green coloring
- Standing on the EXIT completes the level
- Triggers the transition to the next, more challenging level
Exploration Tip: Before heading to the EXIT, explore the level thoroughly for hidden crystals and health pickups. Once you reach the exit, you can't go back!
Visual Feedback and Indicators
Corefall provides several visual cues to aid your navigation:
Color Coding
- Orange/Red: Hazards (lava, enemy drones)
- Brown: Safe platforms
- Blue: Collectible crystals
- Red Hearts: Health pickups
- Green: EXIT elevator (goal)
- Yellow: Vent boost platforms
- Gray with Arrows: Conveyor belts
Particle Effects
- Breaking blocks create debris particles
- Collecting crystals produces a sparkle effect
- Taking damage shows impact indicators
- Vent platforms emit upward particle streams
Understanding Difficulty Progression
Early Levels
The first few levels introduce mechanics gradually:
- Simpler platform layouts with fewer gaps
- Minimal enemy presence
- Ample health pickups
- Generous spacing between hazards
Mid-Level Challenges
As you descend deeper, complexity increases:
- Narrower platforms requiring precision
- More frequent drone patrols
- Complex conveyor belt puzzles
- Increased falling debris
- Lava pits with minimal safe zones
Deep Core Intensity
The deepest levels test all your skills:
- Multiple simultaneous hazards
- Precise timing requirements
- Scarce health pickups
- Complex multi-path navigation
- Maximum difficulty platforming challenges
Common Beginner Mistakes
1. Rushing Into Unknown Areas
Moving too quickly without surveying ahead often leads to falling into lava or running into drones. Take a moment to observe the environment before advancing.
2. Ignoring Conveyor Belt Direction
Conveyors can help or hinder you. New players often forget to account for the push effect, leading to overshooting platforms or falling short of jumps.
3. Wasting the Double-Jump
Using your double-jump too early in a jump sequence leaves you with no recovery option. Save it for course corrections or emergency situations.
4. Greed for Crystals
Going for every crystal, especially when low on health, often results in death. Sometimes survival is more valuable than points.
5. Not Using Invincibility Frames
After taking damage, many players retreat unnecessarily. Use your brief invincibility to advance through dangerous sections.
