Achieving 100% completion in the Unharvest demo by SkorpionDev requires draining life from every stalk of wheat in the map while recovering seven hidden artifact cards. Progress is tracked by the percentage counter in the top-left corner alongside your collected skull currency. Completing the entire field generally takes between 23 and 46 minutes depending on upgrade routing and how quickly you locate the final stray crops.
Core Upgrade Progression
Progress in Unharvest accelerates exponentially once you move beyond manual clicking. Spending skulls in the Tab menu improves your decay efficiency across four main branches: manual withering, passive spore infection, automated movement aura, and the active locust swarm.
| Upgrade Name | Observed Cost Range | Key Mechanical Benefit |
|---|---|---|
| Stalks per Wither | 5 to 5,000 Skulls | Increases target volume per action from 1 up to 20 stalks |
| Wither Cooldown | 10 to 100,000 Skulls | Reduces action delay from 3.0 seconds down to 0 seconds |
| Unlock Spores | 100 Skulls | Adds a passive proc chance to contaminate neighboring crops |
| Spread Chance & Radius | 250 to 20,000 Skulls | Raises spore trigger rate to 50% and expands radius to 15 meters |
| Hold to Wither | 1,000 Skulls | Allows continuous harvesting by holding down the mouse button |
| Critical Wither & Reward | 100 to 25,000 Skulls | Adds a chance for red critical procs that grant bonus skull currency |
| Unlock Locust Swarm | 10,000 Skulls | Unlocks an active right-click skill that clears paths across the map |
| Wither as You Walk | 20,000 to 75,000 Skulls | Drains crops automatically upon walking past them |
Purchasing Hold to Wither early eliminates repetitive clicking, while Spores and Wither as You Walk provide the bulk of passive currency needed to purchase late-stage upgrades. Locked nodes visible in the demo skill tree—such as Blight, Rats, and secondary Swarm charges—are reserved for the full release.
Locating All Seven Artifact Cards
Reaching 100% completion involves discovering seven illustrated cards scattered across the farm. These interactable items sit directly on the ground or near specific farm structures:
- Prayer: A burning, tattered paper card resting among the wheat near your starting area.
- Warning: A sketch depicting a golden field under the sun with a looming dark figure encroaching from the right edge.
- Count: A ledger page displaying tally marks, found further out along the crop rows.
- Feast: An illustration referencing the locust swarm consuming the unharvested crops.
- Omen: A depiction of four horse-mounted figures representing Conquest, War, Famine, and Death.
- Visitor: A drawing showing a family alongside a tall horned silhouette standing outside the windmill.
- Unpaid: A document bearing archaic script and a distinct fingerprint mark.
The farm also contains non-card interactive landmarks that flesh out the setting:
- The Scarecrow: Interacting prompts the text "It's been watching the whole time."
- The Gravestone: An inscribed marker that reads "They'll be back for the rest."
- The Rocking Horse: Located near the barn, labeled "A gift from before the field went quiet."
- Grain Sacks: Found by the barn exterior, displaying "They were saving this. For what, I wonder?"
- The Scythe: Found propped by the fences, displaying "Still sharp. Won't matter."
- The Tree Stump: Prompts a sit interaction that shifts the camera to overlook your decayed field.
The Perimeter-First Clearing Strategy
A common obstacle when aiming for 100% completion is getting stuck at 98% or 99%, searching for isolated, single standing stalks. The perimeter-first method avoids this bottleneck:
- Clear the outer fence borders first by walking the full edge of the boundary fence.
- Work inward toward the central farm structures, using manual withering to create distinct borders.
- Aim your Locust Swarms into the thickest interior clusters rather than toward the edges, preventing swarms from wasting duration on fence lines.
- Track down the artifact cards before triggering the final cluster, as glowing items are far easier to identify against standing yellow wheat than black soil.
Environmental Decay Milestones
As your decay counter approaches 100%, the environment undergoes progressive visual and audio transformations. Specific on-screen messages signal these shifts:
- Early Stage ("They noticed this morning."): Ambient background music plays steadily while black corruptive patches spread underfoot.
- Mid Stage ("The sky is getting quiet."): Flying birds and butterflies scatter and vanish from the area. The sky loses its warm daylight tone, shifting to a dull, overcast grey.
- Late Stage ("The mill stopped. Nobody came to fix it."): The spinning blades of the windmill grind to a halt. Outer boundary trees wither into barren wood, and screen edges develop dark vein vignettes.
- 100% Completion ("Nothing left."): All background music cuts out completely, leaving only the ambient sound of blowing wind.
Once every stalk is eliminated, the demo presents a summary screen showing your total completion time along with an announcement for the full game release, scheduled for December 7, 2026.
Frequently Asked Questions
Does sitting on the tree stump lock the game?
No. The tree stump provides an optional prompt to sit and view the desolation you have created across the farm. Pressing the movement or interact key lets your character stand back up and resume clearing crops.
Why do Locust Swarms veer off in unexpected directions?
Locust swarms travel in predetermined paths toward live crops once released. If an initial target patch is withered before the swarm arrives, the insects redirect toward nearby surviving clusters.
Can Blight or Rats be unlocked in the Unharvest demo?
No. The skill tree entries for Blight and Rats are previews for future content. Attempting to click these terminal skills displays a notification stating they are reserved for the full version.
