Echo Location

TACTICAL FEED ON: WELCOME TO SUB-SURFACE COMMAND

You are coordinates-deep in absolute darkness. The walls are invisible. Patrolling hostiles are hidden in the shadows. Your only window into survival is a cold sonar pulse. Can you memorize, adapt, and escape before the visual fades?

Sub-Surface Command: Echo Location is an intense tactical grid-stealth thriller where you must complete critical evasion runs inside procedurally generated labyrinth networks using active radar telemetry. Every step is an exercise in blind timing, memory, and split-second reflexes.

📡 SURGICAL SONAR MECHANICS
• Echo Sonar Ripple: An automated radar sweep pulses through the deep every 2.0 seconds. It briefly illuminates the surrounding maze structures, hazards, and patrolling anomalies. Study the layout instantly—and run while the feedback decays!
• Manual Sounding Blasts: Pick up scattered Sonar Batteries to secure manual tactical pulses. Trigger an instant radar wave precisely when you need to reveal a blind corner or dodge close-range hostiles.

🔋 SURVIVAL GEAR & SCAVENGED SUPPLIES
• Sonar Batteries: Power up your auxiliary sub-systems. Every battery found secures an instant active-sonar blast.
• Defensive Shields: Increase your damage resistance. Striking a dangerous sub-surface monster drains one Shield Core and teleports you back to the Insertion point. Run out of shields, and your signal is permanently lost.
• Exit Portal Vaults: Located at the farthest edge of the tactical sector. Navigate the pitch-black tunnels, trace the coordinates, and dock with the gate to finalize level completion.

👾 PROGRESSIVE TENSION & UNLIMITED SEEDS
No two operations are ever the same. Enter custom numeric Coordinate Seeds to generate infinite variations of the maze networks. With every level you secure, the sectors scale up in grid size, hazard density, and hostile patrolling speeds. Play random coordinates or input specific custom Seeds to challenge your friends!

⚡ KEY FEATURES:
• Breathtaking Retro Neon Aesthetics: Immerse yourself in a high-contrast vector radar visual style, dripping with classic cybernetic greens, signal blues, and telemetry lasers.
• Pure Stealth Evasion Gameplay: No guns, no backup. Just your memory, your shields, and a tracking pulse.
• Procedural Level Engine: Input any number to generate a completely distinct tactical sector.
• Local Tactical Logs: Detailed database tracking of your deepest level reached, total insertion runs, victory ratios, and historic seed configurations.
• Tablet & Adaptive Support: Polished edge-to-edge layout designed to scale perfectly on mobile screens, foldables, and larger sub-surface monitors.

🛠️ PILOT'S MANUAL (QUICK-START BRIEFING)
