Level 1 Walkthrough

Starting Position

Remember: Enemies Are Invisible!

When the level starts, you won't see any enemies. This is normal! Use your echo pulse (SPACE) to reveal them.

Step-by-Step First Level

  1. Press and hold SPACE to emit your first echo pulse
    • You'll see enemies briefly highlighted in purple
    • Count how many enemies you spotted
    • Note their positions relative to walls and corners
  2. Select Pulse Gun (Press 1) - it's the most beginner-friendly
    • Good damage and high fire rate
    • Forgiving for new players
  3. Move towards the nearest enemy using WASD keys
    • Keep some distance - don't get too close
    • Use short echo pulses to track enemy movement
  4. Line up your shot and click to fire
    • Lead your target if the enemy is moving
    • Fire multiple shots for better hit chance
  5. Repeat for all enemies in the level
    • Level 1 typically has 3-5 Basic Stalkers
    • They move slowly and predictably

First Game Tips

Essential Survival Tips

Tip Why Important How To
Keep Moving Enemies hurt on contact Never stand still, use WASD constantly
Manage Energy Echo pulses consume energy Short pulses, not continuous holding
Use Walls Enemies can't pass through Put walls between you and enemies
Stay Calm Panic leads to mistakes Take time to aim, breathe

Common Beginner Mistakes

  • Holding SPACE too long: Wastes energy quickly
  • Standing still while aiming: Makes you an easy target
  • Rushing into groups: Take on enemies one at a time
  • Not switching weapons: Each weapon has optimal use cases
  • Ignoring health/energy bars: Monitor your status constantly

Your First Victory

Level Completion

Congratulations!

When you eliminate all enemies in Level 1, you'll see your first victory screen with score breakdown and performance statistics.

Score Breakdown

  • Base Score: Points for each enemy eliminated
  • Accuracy Bonus: Extra points for good shooting
  • Speed Bonus: Bonus for fast completion
  • Perfect Clear: Extra bonus if no damage taken
  • Mode Multiplier: 1.0x for Guest, 1.5x for Wallet mode

Next Steps

Continue Your Journey

After completing Level 1, you can either continue to Level 2 for a bigger challenge, or restart Level 1 to improve your score and accuracy.

Progression Recommendations

  1. Master Level 1: Get a perfect clear (no damage, 100% accuracy)
  2. Try different weapons: Experiment with Scatter Shot and Cannon
  3. Connect wallet: Switch to Wallet Mode for rewards
  4. Challenge Level 2: Face your first Shadow Hunters

Wallet Setup

Secure your Web3 gaming experience

Creating Your First Wallet

If you're new to Web3, follow these steps to create your first cryptocurrency wallet:

1. Generate Wallet

  • Open MetaMask extension
  • Click "Create a Wallet"
  • Create a strong password
  • Watch the security video

2. Backup Recovery Phrase

Critical Step

Your recovery phrase is the ONLY way to restore your wallet. Write it down on paper and store it safely offline. Never store it digitally or share it with anyone.

3. Verify Recovery Phrase

MetaMask will ask you to confirm your recovery phrase by selecting words in the correct order. This ensures you've recorded it correctly.

Adding Funds

To participate in Web3 features, you'll need cryptocurrency in your wallet:

Buying Cryptocurrency

  • Centralized Exchanges: Coinbase, Binance, Kraken
  • Direct Purchase: Use MetaMask's built-in buy feature
  • Peer-to-Peer: LocalBitcoins, Bisq

Transferring to MetaMask

1. Copy your MetaMask wallet address
2. In your exchange, initiate withdrawal
3. Paste your MetaMask address as destination
4. Select appropriate network (Ethereum/Polygon)
5. Confirm the transaction
Pro Tip

Start with small amounts when learning. Always double-check addresses and network compatibility before sending transactions.

3 Heavy Cannon High damage, slower speed

Advanced Techniques

Circle Strafe

Move in circles around enemies while firing to avoid their attacks. Combine A/D movement with mouse aiming.

Echo Prediction

Use echo pulses strategically. Enemies move predictably - learn their patterns and predict where they'll be when the echo fades.

Energy Management

Your echo energy regenerates over time. Don't waste it on unnecessary pulses. Save energy for critical moments when surrounded by enemies.

Gamepad Support

Echo Pulse supports Xbox and PlayStation controllers. Connect your gamepad and it will be automatically detected. Button mappings follow standard conventions.

Echo Detection System

Master the core mechanic of invisible enemy detection

How Echo Detection Works

The echo system is the heart of Echo Pulse gameplay. Your cyberpunk robot emits sound waves that bounce off invisible enemies, briefly revealing their locations.

Echo Mechanics

  • Energy Cost: Each echo pulse consumes 20 energy points
  • Cooldown: 1 second between pulses
  • Range: 300 pixel radius from player position
  • Duration: Enemies remain visible for 3 seconds
  • Regeneration: Energy regenerates at 1 point per 0.1 seconds

Visual Indicators

Echo Wave Animation

When you send an echo pulse, you'll see expanding circular waves emanating from your robot. These represent the sound waves spreading outward.

Enemy Revelation

Enemies caught in the echo wave will fade into visibility with a red glowing outline. They gradually fade back to invisibility as the effect wears off.

Energy Bar

Your energy level is displayed in the bottom-left UI. The cyan-colored bar shows current energy, with a lightning bolt icon.

Strategic Echo Usage

Timing Your Pulses

Optimal Timing

Don't pulse randomly. Listen for audio cues like footsteps or enemy attacks. Use pulses when you suspect enemies are nearby or when entering new areas.

Energy Conservation

  • Wait for energy to regenerate between pulses
  • Use the 3-second visibility window effectively
  • Avoid panic-pulsing when surrounded
  • Plan your pulses based on enemy movement patterns

Area Scanning

Move around while pulsing to scan large areas. The echo range is limited, so positioning is crucial for effective detection.

Advanced Echo Techniques

Predictive Pulsing

Learn enemy movement patterns and pulse where you predict they'll be, not where they currently are.

Corner Clearing

Use echoes to safely check around corners and obstacles before moving into dangerous areas.

Combat Pulsing

During combat, pulse when enemies are likely to reposition or when you lose track of their movements.

Energy Management Warning

Running out of energy in dangerous situations can be fatal. Always keep at least 40 energy in reserve for emergency detection.

Weapon Systems

Choose your arsenal wisely

Weapon Overview

Echo Pulse features three distinct weapon types, each with unique advantages and tactical applications. Master all three to adapt to different combat situations.

Weapon Selection Strategy

Situational Switching

The key to mastering Echo Pulse is knowing when to switch weapons. Use the number keys (1-3) to quickly change weapons based on the situation:

// Weapon switching examples
Single enemy at medium range → Echo Pulse Gun
Multiple enemies close range → Rapid Fire
High-health enemy far away → Heavy Cannon
Boss battle → Heavy Cannon + precise timing

Weapon Mastery Tips

  • Practice switching: Get comfortable with rapid weapon changes
  • Learn effective ranges: Each weapon has an optimal engagement distance
  • Count your shots: Know how many hits different enemies require
  • Predict movement: Lead your targets, especially with slower weapons
