zero k strategy guide

Of course. Here is a comprehensive Zero-K strategy guide, covering the fundamentals, core mechanics, and advanced tactics for this highly competitive open-source RTS. What is Zero-K? Zero-K is a free, open-source real-time strategy game in the spirit of Total Annihilation and Supreme Commander. It features: Asymmetric Factions: All units and structures are available to both sides, but each commander start provides a different economic bonus. Physics-Based Projectiles: Shots can miss, be dodged, or intercepted by terrain. Terraforming: The ability to raise/lower terrain, creating choke points or ramps. A Massive Unit Roster: Over 150 unique units, from cheap scouts to colossal experimental units. Complex Economy: Based on Energy and Metal, with storage and conversion between them. Part 1: The Absolute Basics (First 5 Minutes) The Commander: Your Commander (COM) is your most powerful early unit. It builds quickly, fights well, and provides a faction bonus (e.g., faster building, more armor). Protect it. Losing it early is often an instant loss. Starting Economy: Metal Extractors (Mexes): Build these on metal spots (dark, spiky patches on the map). This is your primary metal income. Your first order is almost always to build 2-3 of these. Solar Generators / Wind Turbines: Your starting energy. Build 2-4 energy structures early to avoid stalling. Storage: Build one Metal Storage and one Energy Storage early. This acts as a buffer for your economy and is crucial for reclaiming (see below). The Early Army: Scouts: Build 1-2 light scout units (like Dart or Infiltrator) immediately to see the map, find enemy expansion, and spot for artillery. Raiders: Fast, cheap units (like Spark or Scalpel) to harass enemy metal extractors and builders. Constant early pressure is key. Frontline Units: Start producing a mix of brawlers (like Warrior) and longer-range units (like Ripper) to hold the front line. The Build Order (Standard): COM builds 2 Metal Extractors on nearest spots. COM builds 1 Energy Generator. COM builds 1 Builder Bot (Nano Turret). COM and Builder bot split tasks: more Mexes, more Energy, a Factory (usually Vehicle or Bot Lab), and Storage. Factory starts producing scouts, then raiders. Part 2: Core Strategic Concepts Economy & Expansion: Metal is King: The game is about controlling metal spots. Expand aggressively to them. More mexes = more units. Reclaim is Everything: Press [F] to reclaim. Dead units, wreckage, and even trees/rocks give back resources. A battlefield can fund your entire army. Always reclaim. The Energy-Metal Balance: If you have excess metal but no energy, your construction stalls. If you have excess energy but no metal, you can't build units. Use Metal Makers (convert Energy -> Metal) and Fusion Reactors (expensive, high energy) to balance. Unit Control & Composition: No Hard Counters, But Rock-Paper-Scissors Exists: Tanks beat light units. Anti-Air beats aircraft. Artillery beats static defenses. Swarms can overwhelm heavy units. Jammers (Cloakers) disrupt long-range targeting. Always Have a Mix: A blob of only one unit type is easily hard-countered. Combine frontline, skirmish, artillery, and anti-air. Use Special Abilities: Many units have on/off abilities (Jammer, Shield, Fire-at-will). Learn them. Terraforming & Terrain: Raise Walls (Hotkey: [R]): Create instant choke points to protect your base or block a path. Lower Terrain (Hotkey: [D]): Create trenches for your units to gain cover, or make ramps up cliffs for surprise attacks. Level Terrain (Hotkey: [E]): Essential for building large structures or smoothing a path for your Experimental units. Intelligence & Vision: You can't shoot what you can't see. Use scouts, radar towers, and radar satellites. Jamming towers can hide your army's movement. Part 3: Mid-Game & Tech Transitions T2 (Advanced Labs): Don't rush to T2 too early. A strong T1 economy and map control is better than a fragile T2 army. Transition when: You have secured multiple metal spots. Your T1 army is holding the line. You have the energy surplus to support expensive T2 construction. Key T2 Units: Merl / Tremor: Mobile artillery. The backbone of most mid-game armies. Always protect them with a frontline. Manticore / Pillager: Heavy assault tanks. Your new frontline. Skuttle: A versatile cloaked raider/assassin. Great for killing artillery and commanders. Advanced Air: Gunships (Raptor) for anti-ground, fighters for air superiority. Advanced Economy: Advanced Metal Extractors yield more from spots. Metal Makers become crucial. Place them behind your lines. Fusion Reactors are huge energy targets but power your late game. Part 4: Late Game & Experimentals The Experimental Goal: Experimentals are game-enders, but they are massive resource sinks. Building one is a strategic decision that leaves you vulnerable. Famous Experimentals: Juggernaut (Ragnarok): A walking fortress with a massive artillery cannon. The classic siege unit. Cathedral: A flying carrier that produces and repairs aircraft. Controls the skies. Scathis: A fixed, map-spanning artillery. Requires immense protection. Hollowpoint: A fast, drilling unit that emerges behind enemy lines. How to Win with/against Experimentals: To Use: Secure your economy first. Build heavy defenses (Shield Generators, Anti-Nuke) around its construction site. Have a large supporting army. To Counter: Don't let it be built. Constant scouting and harassment. If it's built, swarm it with cheap units (like Fiends), use bombers, or hit it with your own Experimental. Ignore it and kill the enemy economy is also a valid strategy. Part 5: Pro Tips & Common Mistakes Hotkeys are Mandatory: Learn build hotkeys (F1-F4 for structures, Q-W-E-R for units). Use Area Reclaim (Alt+F). Use Repeat Build (Shift+Click). Overflow Building: If your metal is maxed, you're wasting income. Constantly produce builders, units, or expansions. Don't Clump Your Economy: Spread out your metal makers and fusion reactors. A single bomber run shouldn't cripple you. The "Mex Rush": In team games, a coordinated rush to kill enemy metal extractors in the first 3 minutes can win the game. Use the "Fight" and "Patrol" Commands: More effective than right-clicking for moving armies. Watch Replays: The single best way to improve. See the map from your opponent's perspective. Final Word: Zero-K has a steep but incredibly rewarding learning curve. The community is generally helpful. Play 1v1s to learn fundamentals fast, and don't be afraid to ask questions in-game. The most important strategy is to always be doing somethingbuilding, scouting, or attacking. Good luck, Commander.
