What Is Echo Zero?
Echo Zero is a co-op roguelite where you descend into a procedurally generated sci-fi underworld as an expendable clone. You explore, gather resources, build and defend a base, and battle a rapidly mutating alien species called Organism K2. Every death transfers your mind to a new randomly generated clone — the hive gets closer to the surface each time you fail.
Developed by Wildboy Studios, Echo Zero blends exploration (think Deep Rock Galactic), base-building (Factorio-lite), and tower defense into a single package. The AI overseer JUNO watches your progress, dispensing upgrades and privileges while tightening her hold over your mission. You can play solo or with up to 3 other players in online co-op.
The game is currently in a pre-release state on Steam (Coming Soon). Price TBA.

Core Gameplay Loop
A typical Echo Zero run follows this cycle:
Descend → Explore → Gather → Build → Defend → Extract (or Die)
Descend: Each run starts at the DOME elevator. You pick your loadout and descend into a new procedurally generated sector.
Explore: The underground is a network of caves, tunnels, and hive chambers. Resources, loot, and threats are randomized. Violet Bloom zones mark high-risk, high-reward areas where Organism K2 is most active.
Gather: Collect scrap, organic matter, rare minerals, blueprints, and data caches. Everything feeds back into your base and upgrades.
Build: Your base's heart is the generator. Surround it with barricades, turrets, droid workshops, and support structures. Every build choice affects your survival during defense waves.
Defend: Enemy waves attack your base on a timer. The generator must survive. Randomized upgrade paths mean you can't rely on the same strategy every run.
Extract or Die: Complete objectives to earn extraction rights. Die and you respawn as a new clone, losing unbanked resources.
Getting Started — First Runs
Choose Your Loadout
Starting equipment is basic but functional:
| Slot | Equipment | Purpose |
|---|---|---|
| Primary | Scavenger Rifle | All-round weapon, decent at all ranges |
| Secondary | Mining Laser | Resource gathering, weak combat use |
| Ability | Scouting Drone | Reveals nearby rooms and threat levels |
| Utility | Repair Kit | Heals structures and droids |
First upgrade priority: Upgrade your Scouting Drone to Mark II (reveals resource nodes). Knowing where resources are → faster gathering → stronger base → survival.
First 10 Minutes
-
Scout the perimeter of your starting room before building anything. Check all four exits. If one leads to a Violet Bloom zone, wall it off immediately.
-
Place the generator in a central, defensible position. Avoid corners — enemies can attack from multiple angles if you're pinned.
-
Build two barricades at the most exposed entrance. One layer isn't enough for the first wave.
-
Scavenge everything within your safe zone before the first wave timer hits zero. Scrap is the universal resource — gather it obsessively.
-
First wave arrives at the 5-minute mark. Don't panic. Basic enemies die to 2-3 rifle shots. Focus fire on the glowing ones (they're squad leaders).
Common First-Run Mistakes
- Building too far from the generator. Turret range is limited. Everything must be within 2 rooms of the generator core.
- Ignoring droid production. A single repair droid doubles your base survival time. Build the droid workshop as soon as you have 50 scrap.
- Over-exploring before wave 1. You don't need every room cleared. You need a defensible base. Build first, explore between waves.
- Saving ammo when it matters. Missed shots don't carry over between runs. Empty the magazine. Resources are replaceable — your generator isn't.
Base Building & Defense
Generator Room Layout
Your generator room should be built with sight lines and fallback positions. The default layout is a square room with four doorways.
Optimal generator room setup:
- Generator in the center, surrounded by a reinforced wall (requires 30 scrap, adds 500 HP to generator)
- Two auto-turrets on opposite corners, covering all four doorways
- One repair droid station in the corner behind the generator
- Ammo fabricator next to the repair station
- Emergency bunker (upgrade) on the far wall — retreat here if the generator room is breached
Turret Types
| Turret | Cost | Best Against | Notes |
|---|---|---|---|
| Auto-Turret | 25 scrap | Basic swarm enemies | Default choice. Reliable. |
| Laser Turret | 40 scrap | Medium armored units | Higher damage, slow fire rate. Place near chokepoints. |
| Flamethrower | 35 scrap | Organic hive creatures | Short range, massive area denial. Violet Bloom zones. |
| Rail Turret | 60 scrap | Elite enemies, bosses | Long range, high damage, slow. One per base is enough. |
| EMP Turret | 50 scrap | Shielded enemies | Disables shields. Only useful against specific enemy types. |
Droid Types
| Droid | Cost | Function |
|---|---|---|
| Repair Droid | 50 scrap | Automatically repairs structures and generator |
| Combat Droid | 75 scrap | Follows you, attacks enemies. Helpful in co-op. |
| Scavenger Droid | 40 scrap | Automatically collects nearby scrap and resources |
| Builder Droid | 60 scrap | Speeds up construction by 50% per droid assigned |
Droid synergy: Combat Droid + Repair Droid = your personal support squad. The Combat Droid tanks enemies while the Repair Droid heals your shield. This combo lets you clear Violet Bloom zones safely.
Wargear & Mutations
Wargear are passive upgrades found in chests and data caches. They occupy limited slots (3 base, expandable to 6).
Top-Tier Wargear
| Wargear | Rarity | Effect | Best Build |
|---|---|---|---|
| Nanite Regenerator | Uncommon | +1 HP/sec passive heal | Any build |
| Shield Capacitor | Rare | +50% shield capacity | Tank build |
| Ammo Synthesizer | Uncommon | 10% chance to not consume ammo | Rifle build |
| Droid Commander | Rare | +1 droid capacity, +15% droid damage | Droid build |
| Reactive Plating | Common | Take 20% less damage from melee | Frontline build |
| Scanner Booster | Uncommon | +30% resource discovery range | Scavenger build |
Mutations (Risk/Reward)
Mutations are powerful buffs with a downside. You can carry 1 base, expandable to 2.
| Mutation | Effect | Downside |
|---|---|---|
| Hive Blood | +50% damage to Organism K2 | -30% damage to other enemies |
| Overclocked | +40% fire rate | -25% accuracy |
| Regenerative Tissue | Auto-heal out of combat | -40% max HP |
| Resource Hoarder | +100% scrap from all sources | -50% damage to structures (yours) |
| Ghost Protocol | Enemies detect you 60% slower | Can't use abilities |
Co-op Strategies
Roles (2-Player)
| Player | Role | Focus |
|---|---|---|
| Player 1 | Commander | Base building, turret placement, resource management |
| Player 2 | Scout | Exploration, combat, droid management |
Roles (4-Player)
| Player | Role | Focus |
|---|---|---|
| Player 1 | Base Builder | Generator room, walls, turrets |
| Player 2 | Resource Runner | Scavenging, mining, crafting |
| Player 3 | Combat Lead | Clearing rooms, droid army |
| Player 4 | Support | Repair, healing, buff station |
Co-op Tips
- Share resources via the communal bank (built next to generator). Players drop scrap into the bank and anyone can withdraw. Set a minimum balance of 50 scrap before spending.
- Divide and conquer during defense waves. One player defends generator, one player clears exterior spawning points before enemies reach the base.
- Revive priority: Repair Droid > Player > Turret. A dead player can be revived by any teammate within 15 seconds.
- Co-op scaling: Enemy HP scales with player count. Two players = 1.5x enemy HP. Four players = 2.5x enemy HP. Bring more turrets per player.
Progression & Unlock System
Between Runs (Meta-Progression)
Resources earned during runs are banked and can be spent on permanent upgrades:
| Upgrade | Cost | Effect |
|---|---|---|
| Clone Quality I | 500 scrap | +20% starting HP |
| Clone Quality II | 1,500 scrap | +10% starting shield |
| Loadout Slots | 1,000 scrap | +1 starting weapon slot |
| Droid Blueprints | 800 scrap | Unlock new droid types in shop |
| Base Templates | 600 scrap | Start with pre-built barricade layout |
| JUNO's Favor | 2,000 scrap | Start with one random wargear equipped |
Best first upgrade: Clone Quality I > Loadout Slots > Base Templates. Survivability lets you explore longer, which gathers more scrap for all other upgrades.
