Unharvest reach upgrades determine how much wheat you can clear across the field with a single action. Expanding your reach shifts gameplay from slow single-stalk targeting into wide-area contamination through spore propagation, wide-angle locust swarms, and passive perimeter decay. Maximizing radius and spread distance allows you to bypass tedious border cleanup and strip the terrain down to zero percent remaining crops.

Developed by SkorpionDev, the reverse-farming incremental game requires players to spend withered crop points on the Tab upgrade tree. Investing in reach early multiplies point income rapidly because larger areas catch neighboring wheat patches automatically.

How Reach and Area of Effect Work in Unharvest

Area clearing in Unharvest relies on three separate reach systems rather than a single range stat:

  1. Targeted Stalk Count: Increases the raw quantity of wheat bundles gathered per click, scaling from 1 stalk up to 2, 3, 5, 8, and 20 stalks.
  2. Spore Infection Radius: Controls the radial blast zone around an infected stalk whenever the passive spore trigger procs.
  3. Locust Swarm Width and Travel Distance: Determines the physical corridor width and travel distance of the active projectile launched via right-click.

Early gameplay forces manual interaction with individual crops near the starting point. Once spore reach expands past 3 meters, clearing switches from linear lines to wide circle pockets across the grassland.

Spore Infection Spread Radius and Probability Upgrades

Unlocking spores costs 100 points and introduces a secondary bloom that infects nearby stalks. In early tiers, spores only trigger at a base 10% chance within a narrow 1-meter radius. Upgrading both probability and radius together ensures that clearing one patch automatically chains into adjacent wheat.

Upgrade NameCost (Points)Reach / Effect Value
Unlock Spores100Unlocks passive contamination on click
Spread Radius Level 1250Expands infection radius to 3 meters
Spread Radius Level 21,000Expands infection radius to 6 meters
Spread Radius Level 37,500Expands infection radius to 10 meters
Spread Radius Level 420,000Expands infection radius to 15 meters
Spread Chance Tier 1250Increases infection probability to 25%
Spread Chance Tier 24,000Increases infection probability to 40%
Spread Chance Tier 310,000Increases infection probability to 50%

At a 15-meter spread radius paired with a 50% infection probability, a single activation can engulf dozens of stalks in one cascade. In the demo, the spore branch ends after the 15-meter tier, displaying a locked node for Blight reserved for the full game release.

Locust Swarm Range and Travel Distance Upgrades

The locust swarm is purchased for 10,000 points and functions as an active projectile fired across the map with right-click. While it starts on a lengthy 60-second cooldown with a narrow corridor, upgrades increase its path width, projectile speed, and active flight time.

Swarm Corridor Width

Basic swarms cut a narrow lane through the wheat. Purchasing swarm radius upgrades widens the path:

  • Initial swarm path covers roughly 5 to 8 meters across.
  • Tier upgrades expand the cut to 12 meters, 20 meters, 25 meters, and up to 30 meters.
  • A fully widened swarm carves a massive highway through the field, often harvesting thousands of crops in a single flight.

Swarm Speed and Flight Duration

Reach also depends on how far the swarm travels before dissipating:

  • Duration Upgrades: Base flight lasts 6 seconds, extending to 12, 18, and 25 seconds through successive purchases (costs ranging from 2,500 to 8,000 points).
  • Speed Upgrades: Increases movement from 25 meters per second up to 40 meters per second.
  • Cooldown Reductions: Swarm recharge drops from 60 seconds down to 45, 35, and 30 seconds.

Aiming a max-width swarm from one border toward the far windmill or farm fences clears entire map quadrants without player movement. Upgrades beyond the 30-meter tier, including additional swarm charges and rat summons, remain locked in the demo build.

Walk-Withering and Zero-Cooldown Field Clearing

Physical player positioning serves as the final reach mechanic. While early gameplay requires clicking or holding down left-click (unlocked via "Hold to Wither" for 1,000 points), late-stage progression automates harvesting as an aura around your character.

  1. Wither as You Walk: Acquired in the mid-game upgrade tier for 10,000 to 20,000 points, this upgrade automatically withers wheat when walking into its collision box without clicking.
  2. Critical Wither Radius: Combining walking decay with Critical Wither Chance (scaling up to 20%) and Critical Wither Rewards grants extra points per tick as you run along boundaries.
  3. Zero-Second Cooldown: Costing 100,000 points, this pinnacle demo upgrade removes the withering cooldown entirely. Walking across the field instantly strips any crop entering your proximity radius.

Once the zero-second cooldown is paired with maxed swarm radius, reaching 100% field sterilization takes under 25 minutes. Leftover solitary stalks stand out against the black terrain, making clean-up straightforward as environmental landmarks such as the windmill stop spinning.

Frequently Asked Questions

What reach upgrade should be purchased first in Unharvest?

Unlocking Spores for 100 points and immediately purchasing the 3-meter Spread Radius for 250 points offers the strongest early area improvement. This replaces single-stalk clearing with multi-target blooms before you save up for the 10,000-point locust swarm.

Does locust swarm range persist through the entire map?

Yes, high-duration locust swarms travel continuously until their active timer expires. When upgraded to 18 or 25 seconds with 40 m/s travel speed, the swarm can traverse the entire length of the demo farm map and reach outer boundary fences.

Are higher reach tiers locked in the demo version?

Yes, several late-tier upgrades are disabled in the playtest demo. Nodes marked for the full release include Blight, Rust, Rats, and secondary swarm counts. The full version is scheduled to launch on December 7, 2026.
