Sir We Have an Orc Problem Tower-Only Challenges

Why tower-only challenges exist

Steam discussions during launch week repeatedly ask: “Using towers only, how close can you stop the horde on Level 5?” Sir, We Have an Orc Problem gives you missiles, bombing runs, orbital lasers, and nukes - but the skill ceiling many players chase is automation: a kill zone so strong that turrets alone hold the line while abilities sit unused as emergency backups.

Tower-only challenges are not an official game mode. They are community rules that stress-test placement, meta unlock order, and whether your Flamethrower front actually covers the full fluid stream. This page collects those goals, links to map-specific walkthroughs, and explains how to verify your build with Damage Statistics instead of forum bragging.

Level 5 fully automated flawless clear reference

Rules players commonly use

There is no single enforced ruleset, but launch-week threads converge on:

1. Turrets carry the wave - abilities may exist on the bar but should not be required for the clear.
2. Flawless optional tier - zero leaks separates a “tower-only win” from a “tower-only perfect clear.”
3. No pause-menu exploits - June patches fixed multi strafing runs from pause; older clips may show banned tricks.
4. Same meta tree - copying tower counts from a video without matching upgrades invalidates the comparison.
5. Document the map - Level 5 is the demo-famous benchmark; late campaign maps add six-figure counts with the same philosophy.

Use Perfect Clear Guide for bonus currency context when flawless runs matter.

Level 5 as the benchmark map

Level 5 received visual polish in June demo patches and sits in the scaling band developers flagged alongside Level 4. It is wide enough that Flamethrower fronts dominate community damage charts when placement forces every orc through fire once. It is also fast enough that static Gunner lines from earlier maps leak without rebuilds.

Watch the embedded fully automated flawless clear for reference geometry, then adapt to your unlock set. The clip proves automation is possible; it does not mean your first attempt should skip Level 5 Walkthrough scouting steps.

Tower-only checklist for Level 5:

• Economy nodes so repeat attempts fund caps
• Flamethrower front covering full approach width
• Gunner or Cannon penetration through the burn zone
• Mortar shells on merge clumps, not scatter fire
• Damage Statistics unlocked to verify which line carries
• Zero reliance on missiles during the mid-wave spike

If you must click abilities to survive, your automation is not ready - buy nodes or rebuild the weak segment.

Meta unlocks that enable automation

Automation fails when the tree is thin. Before declaring tower-only impossible, confirm:

• Multiple tower cap increases for Gunners and Flamethrowers
• Penetration on Gunners or Cannons for stacked hordes
• Mortar explosion radius before duplicate Mortars
• Flamethrower tick reliability from post-June balance (at least one tick per orc)
• Optional Headhunter if tanky leaks survive softening (Combat Upgrades)

Spend between attempts using Upgrade Priority and Meta Farming Runs etiquette - finish runs for flat Bonus Resources if purchased.

Reading Damage Statistics honestly

After a tower-only attempt, open the post-battle readout. Compare Flamethrower burn totals to Mortar and Cannon damage. If flames win by an order of magnitude, your funnel works. If Gunners carry while flames tick air, orcs bypassed the cone - rebuild before chasing another cap node.

Forum threads titled “Flamethrowers are completly OP” often come from wide Level 5 approaches where every orc passes fire. Narrow chokes tell the opposite story. Let data settle arguments: Flamethrower Strategy.

Beyond Level 5

Late campaign maps push 50,000 to 100,000+ orcs with faster per-level move speed. Tower-only philosophy still applies - abilities become insurance, not primary DPS - but the meta tree must be wider. Continue into Late-Game Walkthrough and Beat Hard Levels before expecting automation on finale maps.

Some players set personal challenges: no nukes ever, Flamethrower-only fronts, or zero Mortars. Those are self-imposed constraints for replay value after the first clear, not requirements for finishing the campaign.

Missiles versus bombing runs in challenge runs

Community feedback notes missiles feel weak after unlocking bombing runs on mid maps. Tower-only challenges sidestep that debate by forbidding reliance on either. For normal progression, see Abilities Tier List - missiles remain S tier early, bombing runs S tier mid.

When tower-only is the wrong goal

Skip tower-only bragging rights if:

• You still leak on frontier maps and need farm income
• You enjoy active ability timing more than placement puzzles
• Your hardware stutters during huge swarms and abilities mask DPS gaps
• You are learning the game for the first time - learn abilities first, constrain later

Sir, We Have an Orc Problem is a short four-to-six-hour campaign. Tower-only challenges extend replay for optimisation fans, not gate beginners.
