Over the Hill 100 Percent Completion Guide: Full Checklist

A flawless clear of Over the Hill is genuinely doable, but only if you treat it as a planning project instead of a freeform wander. This over the hill 100 percent completion guide turns the entire endgame checklist into one readable roadmap: every trail, every wildlife photo, every crate, every challenge run, and every achievement tied to the post-1.0 build. The value of front-loading a plan is real, because a completionist sweep of a 62-achievement open world can easily run 40+ hours if you bounce between biomes without a route.

Before touching the throttle, it helps to know what "100 percent" actually means in the current build. Community tracking puts the achievement list at 62 entries on Steam, with the rarest tier sitting below 5% of players and the most common "Dirt Baptism" tier already at roughly 89%. Those numbers frame the rest of this guide: if 89% of players finish the tutorial trail, then the gap between "casual clear" and "completionist clear" is almost entirely the long tail of rare and endgame achievements.

What 100 Percent Actually Means in Over the Hill

The first job in any completionist run is defining the finish line. Over the Hill doesn't have a single "All Done" achievement, so the over the hill 100 percent completion guide has to combine several overlapping trackers: the Steam achievement list, the in-game Wildlife Compendium, the Collectible Map completion percentage, and the cosmetic / currency ladders attached to Pebbles and Trail Tokens. Tracking those ladders alongside the rest of the collectibles is exactly the kind of side-mission tracking the Over The Hill Progression Guide walks through, so pairing it with your main completion pass keeps Pebbles and Trail Tokens from slipping through the cracks. Tidying those leftover ladders alongside the rest of the collectibles is exactly the kind of side-mission tracking the Over The Hill Progression Guide walks through, so pairing it with your main completion pass keeps Pebbles and Trail Tokens from slipping through the cracks while ensuring you don't miss the game's broader pacing milestones along the way.

The Four Completion Pillars

These four pillars cover almost every Steam achievement when combined. The remainder (fleet owner, peak currency, region pass stamps, hidden story flags) overlaps with one of the four categories above, so the table is also a checklist: if your four pillars are at 100%, your achievement page is at 100% too.

Mapping Achievements to Pillars

If you read the columns top-to-bottom, the order is also a recommended pace. Tutorial and first-hour items clear themselves if you follow a beginner route, cosmetic stacks drop while you farm pebbles, and the hidden / secret cluster is the part most players leave unfinished. Treating that final 5% as a planned "final push" stage is what separates a 97% completion page from a clean 62/62.

The Completionist Play Order

Order matters more than effort. The over the hill completionist guide works because the game is built so that early unlocks feed into late-game loops: cabins enable fast travel, fast travel enables multi-region sweeps, and the wildlife compendium only starts paying back after you've unlocked the camera. Trying to do things out of order is the single biggest time sink in any 100% run.

According to the official Steam community discussion thread, Steam Community discussion for Over the Hill confirms that accessing every region and collecting all hidden packages is the only reliable path to a full 100 percent completion run, since several missable events won't re-trigger once the finale is triggered.

The Five-Phase Plan

The phase table is a target, not a contract. A patient run can stretch Phase 4 well past 25 hours, while a speed-focused player can compress Phase 2 by chaining cabin-to-cabin routes. The reason the phases are still useful is that each one ends with a clear "you are now ready for the next" signal: a region pass stamp, a new fast travel node, or a vehicle tier that opens a previously locked trailhead.

Phase-to-Region Alignment

The phase-region alignment is built around the same logic as the broader progression guide. If you've already finished your starter hour, this table simply slots you into Phase 2. If you've finished both starter biomes and have a working vehicle, you're ready for Phase 3.

Pillar 1: Beating Every Challenge Trail

The over the hill challenge trails guide is really about turning difficult runs into repeatable practice loops. Challenge trails differ from standard trails in three ways: they have specific vehicle requirements, they often run through deep water or steep rock climbs, and they unlock a tighter set of cosmetic and currency rewards. Most completionists report that challenge trails take 2-4 attempts each on a first clear, and a 70-80% success rate once you've dialled the vehicle and route.

How to Beat Challenge Trails Reliably

The single biggest mistake is treating a challenge trail as a single attempt. Each one has at least two distinct trouble spots, and most have a "save before the climb" point. Players who clear them fastest treat the trail as a three-act structure: approach, technical mid-section, and finish. The approach is the easy 10-15% of the run where you build confidence; the technical mid-section is where the winch, planks, and throttle control matter; the finish is a slow, careful run to the flag. For players learning how to beat challenge trails for the first time, the order of operations inside any one run looks like this: This pattern clears roughly 8 of 10 attempts once it's muscle memory. The remaining 20% are usually environmental (sudden weather, hidden obstacle) and resolve themselves with a second attempt.

• Scout the start of the trail on foot if the map preview is unclear

• Lay planks before the first deep water crossing, not during it

• Use the winch anchor at the steepest climb, not the second-steepest

• Decelerate to a walking pace through the technical mid-section

• Reserve repair kits for the final 30% of the run, not the middle

Challenge Trail Reward Stack

The reward stack is what makes challenge trails worth farming even after your first clear. A second or third run of the same trail is a 5-15 minute investment for 100+ Pebbles, which feeds the cosmetic stack required by the late-game achievements. The cluster of "Pebble ladder" achievements finishes naturally if you treat challenge trails as a repeatable farming source.

Pillar 2: Wildlife, Photo, and the Compendium

The wildlife pillar is the one most players underestimate, because the camera unlocks late and the spawn windows are tight. A 100% clear needs a frame-filling photo of every entry in the regional wildlife list, and a separate "rare animal" photo for the legendary encounter per region. Doing this in one messy pass is the standard reason the wildlife pillar falls to 80% and stays there.

Compendium Targets by Region

The "best time of day" column is where most photo routes fail. Wildlife in Over the Hill is on a spawn timer that doesn't always line up with when you arrive. A common loop is to camp near a spawn zone, fast travel back at the right hour, and re-attempt. The two achievements most affected are the regional Compendium completion flag and the Night Watcher cluster, both of which demand photos at specific times.

Camera Settings for Reliable Captures

• Use a focal length of 70-85mm for mammals and 35-50mm for birds in flight

• Set the aperture wide enough to blur the background but not so wide that focus misses

• Lock the ISO below 800 unless the lighting forces a higher setting

• Use the burst mode for fast animals to guarantee at least one sharp frame

• Keep the shutter above 1/250 for birds, 1/125 for mammals

The Night Watcher achievement is the most common stumbling block in this pillar, because it requires a quality photo in low light. A clean approach is to chain a small set of "night-friendly" animals (owls, foxes, certain deer) into one loop rather than attempting one at a time. If you can clear four in a single night drive, the cluster usually finishes in two or three sessions.

Pillar 3: Collectibles, Crates, and the Map Overlay

The collectible pillar is more about patience than skill. The over the hill completionist guide treats the collectible overlay as a "sweep once and don't go back" task, because re-driving for a single missed crate is the most expensive time sink in the late game.

Collectible Categories and Spawn Rules

The most useful workflow is to mark each region in your mental map as a "sweep" zone: drive a serpentine pattern through the region, mark every collectible node on the in-game map, and finish the region before moving to the next. A good rule of thumb is that a 100% collectible sweep of a region takes 1.5-2x the time of a first clear of the same region.

Why the Crate Economy Matters for 100%

The crate economy is its own mini-game, and ignoring it is the second-most common reason a 100% run stalls at 95%. Crates feed three downstream systems: upgrade materials, Trail Token unlocks, and the cosmetic currency ladder. Players who treat crate routes as a passive activity end up grinding the same area for currency later. Players who actively farm crates during their natural play pass get the late-game upgrades for free.

• Open every Crate you find even if you don't need the upgrade right now

• Stack Trail Tokens before unlocking cosmetic tiers

• Use the Trailhead Trader for utility gear, not cosmetics, until Phase 4

• Save the Summit Vendor for late-game cosmetic purchases

Pillar 4: Achievements, Hidden Flags, and the Last 5%

The most common block point in a 100% run is the final cluster of hidden achievements, story flags, and rare encounter unlocks. These don't fail because they're hard mechanically; they fail because they're easy to miss if you don't know they exist. The over the hill 100 percent completion guide treats this cluster as a separate phase with its own checklist. According to the Steam Community discussion thread for the game, a number of players have shared strategies for tracking every collectible, and this walkthrough compiles those community-verified routes to make a 100% completion run less of a guessing game.

Hidden Achievement Categories

For the rare 5% cluster, the most efficient approach is to filter the Steam achievement list by "global completion %" below 10% and look at the corresponding in-game triggers. Most of these are 10-30 minute tasks once you know the trigger, so the 5% of the run that takes 20% of the time is mostly this cluster.

The Final 5% Checklist

Frequently Asked Questions

How long does a 100 percent clear take?

Players who plan a dedicated "final push" session for this checklist typically clear it in a single 8-10 hour block. Players who try to back-fill these items during normal play end up re-driving regions three or four times. A clean, planned over the hill 100 percent completion guide run usually lands between 35 and 55 hours, with the spread driven by how many times you re-attempt challenge trails and how efficient your photo routes are. A speedrun-completionist with a fully planned route can sit closer to 35 hours, while a casual player back-filling hidden items can stretch to 60.

What's the rarest achievement to clear?

According to Steam's community achievement stats, the rarest cluster sits in the 2-5% completion range and is tied to a specific late-game story flag plus a rare wildlife photo. Both are achievable in a single session if you know the trigger in advance, which is why pre-planning the final 5% is so valuable.

Do challenge trails respawn for re-farming?

Yes. Challenge trails are fully replayable, and each clear pays out Trail Tokens and Pebbles. The most efficient farming pattern is to chain two or three short challenge trails in a single session rather than re-driving a long one, because the per-minute Pebble rate is much higher on the short ones.

Can I 100% the game in a single region?

No. A single region tops out around 40-50% of the achievement list, with the rest gated behind cross-region unlocks, multi-region collectibles, and the late-game story finale. You'll need to visit every biome at least once, and the Algeria region in particular is required for the late-tier achievements.

What's the most efficient order to grind the last 5%?

The cleanest order is: hidden cabins → region-pass stamps → story finale flag → cosmetic stack → rare photo → challenge trail replays for "gold" tiers. This sequence avoids back-tracking, because each item in the chain tends to be in a region you're already passing through.
