What Is Echo Vein?
Echo Vein is a free 2D roguelike mining extraction game by King Peng Studio. You descend procedural caves, mine destructible terrain for resources, fight Hollowborn enemies, defeat sector bosses, and extract before the timer runs out. Choose between three distinct operators — Bulwark, Pathfinder, or Borecaster — each with their own weapon, ability, and upgrade path.
The game is built on HTML5 Canvas 2D with Web Audio, playable in browser or downloaded for Windows, Mac, and Linux. It launched July 2026 and is under active development with a published roadmap.
How to Play
Each run follows a cycle: descend into a procedurally generated cave, mine resources from breakable terrain, fight waves of Hollowborn enemies, complete mission objectives, defeat the sector boss, then extract before time expires.
Resources you mine include Gild Shards (currency), Voltarite (upgrade material), Echo Shards (rare), and various ores. Mining generates heat on your tool — let it overheat and you're briefly vulnerable. Manage heat by pausing or switching to combat.
Missions vary between Hunt (kill X enemies), Survey (reach a certain depth), Harvest (collect X resources), and Holdout (survive waves). Complete missions for bonus rewards.
Between runs, spend Gild Shards on permanent upgrades at the hub. Milestones track your progress across runs and unlock bonuses. Eight synergies provide cross-operator bonuses when you meet specific conditions.

Operators
Bulwark — The armored DPS operator. Wields a Rotary Mauler for sustained close-range damage. Best for players who want to tank hits and shred enemies up close. Has higher base armor and health.
Pathfinder — The mobility operator. Uses a Vector Carbine for mid-range combat and can place traps (proximity mines, slow fields). Best for players who want tactical positioning and area control.
Borecaster — The mining specialist. Carries a Thermal Lance that excels at both mining and combat. Has better heat management, letting you mine longer before overheating. Best for players who prioritize resource collection.
Each operator has an XP track with level cap of 20. At level 20 you can Prestige, which resets the track but grants a stacking permanent bonus for future runs.
Enemies: The Hollowborn
The Hollowborn are the corrupted creatures inhabiting the caves. Over 20 enemy types exist across different biomes. Common types include:
- Skitters — Fast, fragile melee units that swarm in groups
- Shriekers — Ranged enemies that fire projectiles from a distance
- Brutes — Slow, heavily armored melee enemies with high damage
- Leeches — Small enemies that stick to you and drain health over time
Enemy behavior changes based on the biome and sector depth. Deeper sectors introduce tougher variants with new attack patterns.
Boss Fights
Each sector ends with a boss. The confirmed bosses are:
- Hollow Tyrant — A massive armored brute that charges and slams. Dodge sideways, attack during its recovery frames.
- Hex Shard Colossus — A crystalline entity that fires shard volleys. Use terrain for cover and attack the glowing weak points.
- Molten Maw — A heat-based boss that leaves lava pools. Keep moving and manage your position carefully.
Upgrades and Progression
Permanent upgrades purchased with Gild Shards include:
- Health boost
- Damage increase
- Mining speed
- Heat capacity
- Extraction time extension
- Starting equipment upgrades
30+ milestones track cumulative achievements (total resources mined, enemies killed, bosses defeated, extractions completed). Each milestone tier unlocks a reward.
Eight synergies activate when you meet conditions across operators — for example, "Mine 10,000 total ore across all operators" unlocks a global mining speed bonus.
Beginner Mistakes to Avoid
| Mistake | Why It Hurts | Fix |
|---|---|---|
| Ignoring heat management | Overheated tool leaves you unable to mine or defend yourself briefly | Pause mining at 80% heat; let it cool while kiting enemies |
| Skipping side tunnels | Main path has fewer resources; you miss upgrade opportunities | Branch out at least 2-3 rooms from the main path before descending |
| Holding too many resources | Dying before extraction loses everything | Extract early if you're low on health or the timer is tight |
| Ignoring operator prestige | You miss stacking permanent bonuses | Prestige at level 20 even if it feels like a reset |
| Fighting every enemy | Some fights waste resources and time | Run past non-threatening enemies when your objective is clear |
