Axom Unlock Order Guide: Best Progression Path

Understanding the Axom Unlock System

In Axom, progression is not linear. As you defend your fortress and explore the procedurally generated alien world, you will earn resources that allow you to unlock new buildings, upgrades, and abilities. Choosing the right unlock order is critical to surviving the increasingly difficult waves of physics-driven bug swarms. This guide will walk you through the optimal path to ensure your fortress can withstand the corruption.

The game features a tech tree with multiple branches, focusing on defense, economy, and utility. Unlocking items out of order can leave you vulnerable. Our recommended sequence prioritizes survival and resource generation, allowing you to snowball into the late game.

Phase 1: Early Game Essentials (First 3 Runs)

Your first few runs in Axom are about establishing a foundation. Do not chase high-tier towers immediately. Focus on unlocks that give you consistent defense and resource flow.

• Basic Wall Upgrade: Your first unlock should always be the reinforced wall. This simple upgrade doubles the health of your starting walls, giving you crucial extra seconds to react to the first few waves.
• Resource Extractor: This building passively generates scrap metal over time. Unlocking it early allows you to accumulate resources even while you are busy placing towers.
• Repair Drone: A single-use drone that can instantly repair one damaged wall segment. This is a lifesaver against the early swarm rushes and prevents a single breach from cascading into a defeat.

Phase 2: Core Defensive Structures

Once your economy is stable, it is time to build your primary defense line. The following unlocks form the backbone of any successful Axom fortress. They offer the best damage-per-resource ratio for the mid-game.

The Flamethrower Turret is excellent against the clustered bug swarms that appear around wave 5. Its area-of-effect damage can clear a path quickly. Next, unlock the Sniper Post. This long-range tower is perfect for picking off the larger, high-health bugs that threaten your walls from a distance. Finally, invest in the Shield Generator. This building creates a temporary energy barrier that can absorb a full wave of damage, giving your turrets time to eliminate threats.

Phase 3: Economy and Utility Scaling

With a solid defense in place, you must now scale your economy to afford the powerful late-game unlocks. This phase focuses on multipliers and passive effects.

The Trade Hub is the single most important economic unlock. It allows you to convert excess scrap metal into a new, rarer currency used for permanent upgrades between runs. Pair this with the Automated Forge, which slowly upgrades all your turrets over time without costing you any resources. Finally, unlock the Scanner Array. This reveals the composition of the next three waves, allowing you to reposition your defenses perfectly.

Phase 4: Specialized End-Game Unlocks

The final phase of the unlock order focuses on dealing with the corrupted terrain and the final boss waves. These unlocks are expensive but game-changing.

The Purification Beam is a high-energy weapon that damages enemies and cleanses corrupted ground tiles, restoring them to a buildable state. This is essential for expanding your base in the late game. Next, unlock the Tesla Coil. This tower chains lightning between multiple enemies, making it incredibly effective against the massive swarms that appear in the final waves.
