Clearing the demo of Unharvest, the reverse-farming incremental title by SkorpionDev, requires withering 100% of the wheat field by converting dying stalks into skull points and investing in automated plague abilities. A standard run takes between 22 and 30 minutes, ending when every patch of grain is wiped out and the demo completion screen triggers.
The following breakdown outlines the complete upgrade progression, an efficient clearing route, and where to inspect every piece of lore left behind on the farm.
Core Controls and Interface
Unharvest plays from a first-person perspective, placing you in an overgrown agricultural landscape where you drain the life from the environment rather than cultivate it.
- Movement uses standard WASD keys. Running is active by default, and there is no jump mechanic.
- Left-click withers target wheat stalks within reach.
- Right-click unleashes the Locust Swarm once that skill is unlocked.
- Tab opens the upgrade tree and switches over to inspect collected story artifacts.
- The skull counter in the top-left corner tracks accumulated currency, while the percentage below it shows total field destruction.
Upgrade Tree and Milestone Costs
Currency accumulates as stalks collapse. Upgrades unlock sequentially across several distinct branches: direct withering, passive spore propagation, quality-of-life automation, and active locust swarms.
| Upgrade Category | Key Upgrades | Skull Cost Range | Effect on Field Clearing |
|---|---|---|---|
| Direct Withering | Stalks per Wither | 20 to 5,000 | Increases stalks withered per action from 1 to 2, 3, 5, 8, and finally 20. |
| Cooldown Reduction | Wither Cooldown | 25 to 100,000 | Drops delay from 3.0s down through 2.0s, 1.0s, 0.7s, 0.4s, 0.03s, and finally 0s. |
| Spore Propagation | Unlock Spores, Radius & Spread Chance | 100 to 10,000 | Adds a 10% to 50% trigger chance to infect surrounding stalks across 1m to 15m. |
| Automation | Hold to Wither & Wither as You Walk | 1,000 to 20,000 | Removes manual clicking, allowing continuous draining and destruction by walking. |
| Swarm Ability | Unleash Swarm, Speed, Duration & Radius | 2,500 to 35,000 | Launches a targeted locust wave on a 60s base timer that tears across the field. |
| Critical Harvest | Critical Chance & Reward | 100 to 25,000 | Adds a 5% to 20% critical trigger granting bonus currency on harvests. |
Several nodes displayed in the menu, including Rats, Blight, Rot, and Swarm Count +1, cannot be purchased in the demo build and are designated for the full release.
Recommended Walkthrough Path to 100%
Completing the demo swiftly depends on unlocking area-of-effect abilities before chasing expensive single-target stats.
Phase 1: Early Manual Withering (0% to 1%)
The opening minutes move slowly due to the base 3.0-second delay between clicks.
- Target isolated stalks near your spawn point to accumulate your first 20 skulls.
- Open the menu with Tab and purchase the initial Stalks per Wither upgrade to take two stalks per action.
- Put the next earnings into reducing the wither cooldown from 3.0 seconds to 2.0 seconds, then 1.5 seconds.
- Scale Stalks per Wither to three and then five stalks.
- As soon as you hit 100 skulls, purchase Unlock Spores.
Phase 2: Spore Chaining and Automation (1% to 15%)
Unlocking Spores marks the first major spike in clearing speed. Spores have a base 10% chance to spread corruption across a 1-meter radius whenever you wither a stalk.
- Increase the spore Spread Chance to 25% for 250 skulls, then expand the Spread Radius to 3 meters.
- Accumulate 1,000 skulls to unlock Hold to Wither. This removes the need to click repeatedly, letting you hold down the left mouse button while panning across crops.
- Upgrade Spread Chance to 40% (cost: 4,000 skulls) and expand the radius to 6 meters.
- Pick up the first tier of Critical Wither Chance (100 skulls) and Critical Wither Reward to boost skull payouts from automated chain reactions.
- Work along the outer fence boundaries. Clearing the outer perimeter first prevents small patches of wheat from being stranded at the edges later on.
Phase 3: Locust Swarm Deployment (15% to 60%)
Save up 10,000 skulls to unlock the Locust Swarm ability, mapped to right-click.
- Aim the target reticle across dense, untouched sectors of the field and fire the swarm. The swarm charges through the crops, tearing up hundreds of stalks in seconds.
- Use the initial influx of currency to lower the Swarm Cooldown from 60 seconds down toward 30 seconds.
- Invest in Swarm Duration and Swarm Speed. Increasing duration keeps the insects active long enough to cross the entire farm lot.
- At 20,000 skulls, buy Wither as You Walk. From this point forward, simply walking into standing wheat destroys it instantly without mouse input.
- Combine active walking sweeps along fence corners while launching the swarm toward the center of the field on cooldown.
Phase 4: Final Field Cleanup (60% to 100%)
The world darkens noticeably during the late phase: the ambient sky turns dim, insects buzz in the background, and environmental audio dampens.
- Maximize the Spore Spread Chance to 50% and push the radius to its 15-meter cap.
- Max out Locust Swarm Radius to widen the path carved by each launch.
- If you have surplus skulls, purchase the 100,000 skull upgrade to reduce Wither Cooldown to 0 seconds. This eliminates the minor stutter when running through thick crop lines.
- Sweep inward from the fences to catch isolated lone stalks. Standing wheat remains bright gold against the blackened ground, making stragglers visible from a distance.
- Once the destruction meter hits 100%, the completion screen displays your clear time and confirms the demo is complete.
Lore Artifacts and World Interactions
Seven collectible lore documents and several interactive objects are scattered around the environment. Interacting with them (E key) logs their illustrations in the collection menu.
Story Artifact Cards
- Prayer: A damaged, burning holy text found resting on the ground near the early clearing area.
- Visitor: A drawing showing a rural family standing alongside a tall, horned figure on the far right.
- Warning: A sketch depicting dark corruption spreading into a pristine field under the sun.
- Feast: An illustration of a locust devouring wheat stalks.
- Count: A parchment marked with names and tallies counting elapsed time.
- Unpaid: A document bearing ancient script and a marked fingerprint.
- Omen: A depiction referencing the Four Horsemen from biblical apocalyptic tradition.
Interactive Environmental Points
- The Scarecrow: Stands near the center edge of the crops. Interacting yields the message: "It's been watching the whole time."
- The Gravestone: A small burial marker situated near the fence lines. Inspection reads: "They'll be back for the rest."
- The Scythe: Found lying on the ground near the farm structures. Prompts: "Still sharp. Won't matter."
- The Grain Sacks: Found tucked inside an open shed structure. Prompts: "They were saving this. For what, I wonder."
- The Rocking Horse: A wooden toy found resting near the field perimeter. Prompts: "A gift from before the field went quiet."
- The Mill: A small windmill structure at the edge of the property. Once field destruction reaches high percentages, inspecting it notes: "The mill stopped. Nobody came to fix it."
- The Fallen Log / Stump: A rest spot where you can press the prompted key to sit down and observe the barren ground.
Frequently Asked Questions
When does the full version of Unharvest release?
According to official developer data published on the Steam store page, Unharvest is scheduled to launch on December 7, 2026.
Why do some upgrades show locked in the demo?
Upgrades such as Rats, Blight, Rot, and additional Swarm Count increments are demo hard caps. These nodes are reserved for the full release and cannot be acquired in the current free demo build.
Can you enter the barn or the windmill?
The structures on the farm cannot be entered during the demo. While you can approach the doorways and interact with nearby objects like the grain sacks and the windmill exterior, indoor access is blocked.
What should you do if the demo gets stuck at 99%?
If your counter sits between 98% and 99.9%, scan the perimeter boundaries and fence corners. Surviving stalks remain bright yellow, creating a sharp contrast against the blackened soil. Sweeping along the border fences with the Wither as You Walk ability active will clear any missed stalks.
