Sir We Have an Orc Problem Perfect Clear Guide

What a perfect clear means

In Sir, We Have an Orc Problem, a perfect clear (also called a clean win or flawless run) means every orc dies before reaching your base - zero leaks. The end screen distinguishes this from a messy win where the base survives with HP remaining, and from a loss where orcs breach the trench entirely.

Perfect clears matter because they often grant bonus currency used for ability branches, premium upgrade nodes, or faster progression through expensive caps. Not every map pays equally, but the incremental design rewards players who can stabilise kill zones enough to delete the entire horde. This guide explains when to chase perfect clears versus when farm losses are smarter.

Pair it with Economy and Meta Progression, Meta Farming Runs, and Upgrade Priority.

Clean win bonus versus kill currency

Most runs award kill-based meta currency proportional to orcs destroyed. That currency funds Gunner damage, tower caps, and economy nodes whether you win messy or lose late. Clean win bonuses sit on a separate track: tooltips on locked nodes sometimes require currency earned only from perfect clears or survival with full base HP.

Practical pattern on mid campaign maps:

1. Farm messy wins or intentional losses until penetration and caps cross a breakpoint.
2. Rebuild the choke one final time with Damage Statistics open from Combat Upgrades.
3. Push for a perfect clear once DPS clearly over-kills the wave mid-map.
4. Spend the bonus currency immediately on ability unlocks gated behind clean wins.

Hoarding perfect-clear bonuses while your tree lacks baseline DPS wastes time - you could have bought payout nodes during three farm attempts instead of failing flawless runs by one orc.

When to chase perfect clears

Chase a perfect clear when:

• You already survive the wave with base HP to spare
• Damage Statistics shows your kill zone deletes clumps before they reach mid-field
• An ability or upgrade node explicitly lists clean-win currency
• You are one upgrade away from trivialising the map and want to unlock a premium branch
• Community challenges like tower-only automation on Level 5 require zero leaks by definition

Skip perfect clears when:

• You still leak dozens of orcs and need farm income more than bonus currency
• Flat Bonus Resources requires finishing the run anyway - a messy win still counts as finished
• You are on a frontier map where speed-per-level scaling means placement, not perfection, is the bottleneck
• Chasing flawless runs burns session time without buying permanent nodes

Level 4 Walkthrough and Beat Hard Levels assume messy progression first; return for perfect clears after the tree catches up.

Building toward zero leaks

Perfect clears are placement problems before they are stat problems. Standard checklist:

• Scout once - confirm the main fluid stream path with a minimal battle
• Flamethrower front - every orc should burn at least once on wide maps (Flamethrower Strategy)
• Penetration online - Gunners and Cannons must punch through stacked bodies (Choke Points)
• Mortar on merge clumps - shells land where density peaks, not on empty berm
• Ability timing - one bombing run or missile burst during the mid-wave spike, not the opening trickle (Abilities Tier List)
• No panic repositioning - rebuild between attempts, not mid-wave unless abilities cover the gap

Orc move speed increases per level - a layout that perfect-cleared yesterday may leak today after advancing maps. Re-verify choke geometry instead of assuming flawless automation carries forward.

Tower-only and flawless challenges

Steam threads ask how close players can stop the horde on Level 5 using towers only - no ability spam. That is a perfect-clear variant: automation means abilities become backups, not crutches. See Tower-Only Challenges for community goals and links to the Level 5 automated clear clip.

Flawless tower-only clears prove your kill zone is real DPS, not manual cooldown management. They also expose weak segments: if leaks always happen at the same timestamp, rebuild that choke segment before buying another +0.1 damage crumb.

Perfect clear versus surrender etiquette

June demo patches changed Bonus Resources rules: flat bonus no longer pays on surrender. You must finish the level (win or lose) for the flat payout. Perfect clears are wins with zero leaks - they always count as finished.

Do not surrender a near-perfect run hoping to retry faster if you own flat Bonus Resources - you forfeit the flat bonus. Let the last orc die or leak, spend currency, then retry for flawless. Details: Bonus Resources.

Session planning for completionists

Completionists chasing 100% upgrade tree after campaign clear often alternate:

• Farm runs on late maps for kill currency volume
• Perfect clear attempts on earlier maps where geometry is solved for bonus branches
• Planner checks in the Upgrade Planner for nodes still gated by clean-win wallets

Expect four to six hours for first campaign clear plus optional farming sessions. Perfect-clear grinding is optional spice, not mandatory for story completion.

Common mistakes

• Chasing flawless runs before economy payout nodes compound
• Firing all abilities early, then leaking during the real density spike
• Ignoring secondary paths on dual-choke maps while perfecting the primary lane
• Comparing your clear to YouTube automation without matching meta unlocks
• Treating one leaked orc as failure instead of spending and retrying

Launch week context

On July 28, 2026 release day, forums mixed price questions with Flamethrower debates and Level 5 tower-only brags. Perfect clears sit in that skill-ceiling layer - not required for enjoying the campaign, but rewarding for players who love optimisation. First Week Community summarises other launch threads.
