Wall World Speedrun Guide: Early Upgrades and Completion Route

This Wall World speedrun guide focuses on an upgrade-first route: start with a diamond cave, rush plasma cutter improvements, then collect pearls in Lower 1 before heading toward the upper zones. For a full completion, the community guide describes collecting all five crypto keys, opening the gate above the High-tech zone, and defeating the final boss phase beyond it. The route below is a community strategy, not a verified leaderboard route or record-time walkthrough.

Route Scope and Starting Conditions

The main reference is HumanFtw’s Wall World: All You Need to Know, last updated June 9, 2023. Its recommendations cover mining efficiency, equipment, progression, and the base-game finish. Version not independently confirmed for this route; later comments also question an older wave-timing technique.

Before comparing attempts, distinguish a fresh save from one with permanent upgrades. HumanFtw explains that established saves can prioritize mining more aggressively, while a new save needs additional combat investment to survive early transitions.

The guide describes reaching tier 3 plasma in six minutes from a brand-new save. Treat that as the author’s reported opening benchmark—not a full-game completion time or a guaranteed split.

Step 1: Rush the Early Plasma Cutter Upgrades

The opening objective is to improve mining speed without leaving the spider unable to handle waves.

1. Find a diamond cave first. HumanFtw recommends leaving an initial moss cave and searching for a diamond cave instead.
2. Mine six cobalt, then return for the plasma cutter upgrade. This is the guide’s first explicit resource checkpoint.
3. Make another mining trip toward the second upgrade. Return when you can afford it or when the wave begins, whichever happens first. The source gives this checkpoint as “16/4” without naming both resources in that passage, so check the upgrade requirements rather than assuming the resource pair.
4. Finish the first diamond cave, then find a moss cave. The recommended next objective is the third plasma cutter upgrade.
5. Choose whether to leave the starter zone. With fewer permanent upgrades, spend more time building combat strength before attempting the next biome transition.

The important trade-off is mining speed versus survival. An early cutter upgrade accelerates later resource gathering, but skipping necessary weapon investment can make a cloud encounter too costly.

Step 2: Route Through Pearls, Then Toward the Upper Zones

HumanFtw recommends descending to Lower 1’s Sponge biome after plasma cutter level 3, because the level 4 upgrade requires pearls. Afterward, the suggested route turns upward toward Upper 2’s Ice biome for amethysts and a possible Laser Machine Gun find.

The relevant zone progression is:

These are zone associations, not guarantees that every cave contains the expected biome. The guide notes that some caves can use a lower-tier biome and that mossy caves can replace certain diamond caves.

Do not make a specific weapon spawn a mandatory split. The source describes weapon discoveries in special caverns and notes that higher-tier weapons can sometimes appear earlier. Plan around what the attempt actually provides.

Step 3: Reduce Mining and Transport Downtime

The largest practical time savings in HumanFtw’s guide come from combining tasks rather than treating mining, hauling, and fighting as completely separate activities.

Clear From the Back Toward the Entrance

Mine toward the far end of a cave, then work back toward the spider. The guide recommends this pattern because it reduces the distance over which loose resources must be moved and can improve the usefulness of limited-range effects such as the seismic generator.

A full vacuum does not necessarily mean mining must stop immediately. If the wave schedule permits, continue breaking useful rock, then collect resources while returning. On the return journey, carry an equipment module or mine missed side deposits when doing so avoids another dedicated trip.

Practice Resource Juggling Before Relying on It

The guide describes moving loose resources with repeated vacuum handling to transport more than a normal load. However, it also warns that small groups can scatter and oversized groups can slow movement.

Use juggling only when it actually shortens transport. Dropping resources near the spider allows short final collection trips instead of repeatedly hauling from deeper inside the cave.

Overlap the End of Combat With Cave Entry

HumanFtw suggests launching a missile at the last enemy and entering the cave before the projectile finishes the kill. This can put you in position to mine as the next wave countdown starts.

That recommendation depends on the missile reliably finishing the enemy. Leaving a dangerous target alive is not the same time-saving maneuver.

Combat Investments That Support the Route

The source’s weapon and equipment rankings are personal recommendations, not measured speedrun comparisons. Its most relevant options are:

• Machine Gun: Use the starter weapon to handle early waves, but avoid automatically investing past its third upgrade row when stronger alternatives are available.
• Stake Thrower: A potential early-zone find with accurate, long-range damage suited to boss weak points, though less comfortable against large airborne groups.
• Laser Machine Gun: Recommended by HumanFtw for its combination of accuracy, damage, range, fire rate, and turning speed.
• Railgun: Described as a strong boss weapon even without upgrades, normally associated with the High-tech zone.
• Drone system: Automated defense can extend mining opportunities and, with sufficient upgrades, handle waves.
• Resource Harvester: An early find can support resource income; the guide considers it worthwhile but not necessary for victory.

During combat, move the spider rather than remaining docked. Prioritize explosive suicide enemies, especially those approaching closely. HumanFtw places large flying spawners lower on the target list because their direct damage is comparatively low.

Cloud Transitions: Avoid Depending on the Old Timer Trick

Crossing a cloud boundary summons additional enemies, making biome changes a combat checkpoint rather than free travel.

The original guide recommends leaving one regular-wave enemy alive before triggering a cloud encounter to combine the fights. However, an April 23, 2025 comment on the same guide reports that clearing cloud enemies reset the wave bar even when the preceding wave had already ended.

That later observation questions the need for the older setup. Do not build a timing-critical route around the enemy-stalling trick without testing its behavior in your version. The dependable preparation is sufficient combat strength for the transition.

Finish Requirements and Boss Priorities

An efficient opening is not enough to complete the game. According to HumanFtw, the finish requires all five crypto keys, which appear in special treasure rooms within caves across various zones. The supplied guide does not give a complete key-by-key location route.

Once the keys are collected, open the gate above the High-tech zone, pass through it, and finish the third boss phase. The guide describes the third encounter before this progression as lethal, so additional weapon damage does not replace the key requirement.

For the first two boss phases:

• Target the boss’s boils to end each phase.
• Use accurate, long-range attacks such as the Stake Thrower or missiles.
• Move out of red-marked tentacle attack areas.
• Interrupt boss damage when necessary to eliminate threatening suicide enemies.

HumanFtw reports that ending an attack phase destroys remaining enemies, making boss weak points a higher priority than clearing every minor target. The final phase beyond the gate also requires avoiding projectiles.

The resulting practice route is straightforward: build mining speed, secure enough defense for transitions, gather the required keys, and preserve movement and damage for the finish. The six-minute tier 3 plasma opening is a useful community benchmark, but the supplied material does not establish a current optimal full-run time or exact completion splits.
