Current Meta Overview & Tower Tier List
The latest content for Sir, We Have an Orc Problem challenges players with tens of thousands of orcs flooding the map simultaneously. To survive the onslaught, you must rely on a massive upgrade tree and carefully positioned turrets. The game operates on an incremental meta-progression system—meaning even if your base is overrun, you still keep the resources earned to unlock and upgrade powerful defenses for the next attempt.

Understanding which towers to invest in is critical for efficient progression. Below is the current tier list based on overall damage output, utility, and reliability across all available maps.
| Tier | Tower | Strengths | Best Placement |
|---|---|---|---|
| S | Laser Tower | High damage, wall-bouncing AoE | Narrow corridors, angled corners |
| S | Flamethrower | Guaranteed hits, burn damage over time | Entrances and tight choke points |
| A | Machine Gunner | High fire rate, piercing potential | Straight lines, early game defense |
| A | Cannon | Strong area damage, reliable | High congestion zones, center map |
| B | Tesla Coil | Chain lightning, enemy knockback | Behind walls, secondary choke points |
| B | Mortar | Long-range bombardment | Center of the map, major intersections |
| C | Grenade Launcher | Slows enemies, low base damage | Early choke points for crowd control |
Always max out your Laser Tower damage and bounces first. The Laser Tower scales exceptionally well into the late game, capable of handling massive waves in tight corridors without requiring constant attention.
Best Tower Loadouts and Synergies
Building the right crossfire is essential to stop the orc horde. Different maps require unique approaches, but certain synergies remain universally powerful throughout the game.
The Laser Chamber
- Best for: Narrow maps (Levels 1-3)
- Setup: 3-4 Lasers angled to bounce rapidly
- Synergy: Add a Flamethrower at the entrance to weaken targets before they enter the chamber
The Fire Wall
- Best for: Multi-entrance maps (Levels 4-5)
- Setup: Flamethrowers covering every entry point
- Synergy: Upgrade burn damage and bullet penetration against burning enemies
The Slow & Nuke
- Best for: Massive late-game waves (Level 6)
- Setup: Grenade Launchers to clump enemies, Cannons for raw damage
- Synergy: Use the Cryo Beam or Nuke when orcs are tightly grouped
Core Upgrade Paths
Focusing your resources on the right nodes in the upgrade tree will dramatically increase your survivability.
| Upgrade Node | Effect | Priority |
|---|---|---|
| Tower Damage | Increases base damage for all placed turrets | High |
| Explosive Orcs (1%) | Orcs have a chance to explode on death, damaging nearby units | High |
| Bullet Penetration | Bullets pass through burning enemies without consuming pierce | Medium |
| Silver Orcs (1%) | Killing silver orcs grants additional resources | Medium |
| Shocked Enemies | Shocked orcs run in the wrong direction for 1 second | High |
| Health Points | Increases base survival threshold | Low |
Burn damage from Flamethrowers does not stack. Placing multiple Flamethrowers in the exact same spot is inefficient. Spread them out to maximize coverage and keep orcs ignited for as long as possible.
Step-by-Step Progression Guide
To efficiently clear all levels and unlock every weapon, you need a structured approach to farming and upgrading. Follow these steps to establish an impenetrable defense.
Farm Level 1.1 for Early Resources
Start by placing a single Machine Gunner at the main choke point. Even if you lose, you will earn resources for kills. Prioritize unlocking the Laser Tower and Flamethrower as quickly as possible.
Build the First Laser Trap
On Level 1.2, angle your Laser Tower so the beam bounces between walls rapidly. This creates a "laser corridor" that shreds early orcs. Add a Machine Gunner to clean up any stragglers.
Unlock Active Abilities
Prioritize unlocking the Strafing Run and the Explosive Orcs passive. The 1% explosive chance scales incredibly well when facing tens of thousands of orcs, creating massive chain explosions.
Upgrade Tesla Coils for Crowd Control
By Level 3, you need crowd control. Place Tesla Coils at intersections. Upgrade the chain jumps to push orcs backward, forcing them to walk through your damage zones multiple times.
Max Out the Nuke for Level 6
Level 6 features overwhelming numbers. Save your resources to unlock the Nuke ability. Wait for the massive horde to clump up in the center of the map before dropping it for millions of damage.
If a level feels impossible to win, do not surrender immediately. Play it out to farm as many kills as possible. You keep all earned resources regardless of victory or defeat, making failed runs highly valuable for meta-progression.
Achievement Hunting Guide
There are 11 unique achievements available in the game. The most difficult achievements require beating specific levels under strict limitations. Here is how to tackle the toughest challenges.
| Achievement | Requirement | Best Strategy |
|---|---|---|
| Survive 1.1 | Beat Level 1.1 with only a single tower | Use a maxed-out Laser Tower angled for maximum bounces |
| Survive 2.1 | Beat Level 2.1 without any towers | Save up for the Nuke ability and drop it on the grouped horde |
| Survive 3.1 | One tower type, no abilities | Spam Flamethrowers at every choke point; their burn damage melts low-health orcs |
| Survive 4.1 | Only Flamethrower, Tesla, and Cryo Beam | Use Teslas to push orcs back into the Flamethrower zones |
| Survive 5.1 | Three tower types, no abilities | Combine Lasers, Cannons, and Flamethrowers for balanced coverage |
| Survive 6.1 | Four tower types, no abilities | Use Grenade Launchers to slow, Cannons for damage, Teslas for pushback |
| Nuke Damage | Deal 666,000 damage with a single Nuke | Play Level 6.1, let the orcs clump in the center, then detonate |
For the "Survive 6.1 with only four types of towers" achievement, use Grenade Launchers to slow the horde, Tesla Coils to reverse their direction, Lasers for raw damage, and Cannons to finish them off. The Tesla knockback is the secret to surviving the final wave.
Active Abilities and Special Orcs
Active abilities are your panic buttons. They turn unwinnable situations into flawless victories. You must manage their cooldowns effectively to handle the escalating orc waves.
Ability Breakdown
| Ability | Effect | Best Use Case |
|---|---|---|
| Missile Strike | Click to fire explosive missiles | Cleaning up stragglers that leak through your defenses |
| Strafing Run | Calls in an airstrike on a designated zone | Thinning out early waves before they reach choke points |
| Orbital Cryo Beam | Freezes all orcs in its path | Stopping massive congestion from building up |
| Nuke | Massive explosive damage | Clumped waves in the center of the map |
Special Orc Types
As you progress through the update, you will encounter special orc variants that change your target priority.
Special Orc Mechanics:
- Silver Orcs: 1% spawn chance, grant extra resources upon death
- Explosive Orcs: Detonate upon death, dealing damage to nearby orcs
- Red Orcs: Carry explosives, prioritize killing them in groups
Do not waste the Cryo Beam on scattered orcs. Wait until a massive wave gets stuck in a narrow corridor or choke point. Freezing them there allows your Laser Towers and Cannons to deal maximum damage without the orcs advancing.
Advanced Tips and FAQ
Mastering Sir, We Have an Orc Problem requires understanding how different mechanics interact. Here are the most frequently asked questions from the community.
Q: What is the best tower in the current Sir We Have an Orc Problem update?
The Laser Tower is currently the strongest defense. When angled correctly in narrow corridors, its bouncing beam deals massive AoE damage. Pair it with a Flamethrower to weaken orcs before they enter the laser zone.
Q: Do I lose my resources if I fail a level?
No. The game features incremental meta-progression. You keep all resources earned from killing orcs even if your base is overrun. This makes failing early levels a viable strategy for farming upgrades.
Q: How do I deal 666,000 damage with a single Nuke?
Play Level 6.1 or 6.2 and let the massive horde group up in the center of the map. Wait until the orcs are tightly clumped before dropping the Nuke to maximize the splash damage.
Q: Does burn damage from Flamethrowers stack?
No, burn damage does not stack. Placing multiple Flamethrowers in the same spot is inefficient. Spread them out to maximize coverage and keep orcs ignited for as long as possible.
Q: How do I beat Level 6.1 with only four tower types and no abilities?
Use Grenade Launchers to slow the horde, Tesla Coils to push them backward, Lasers for raw damage, and Cannons to finish them off. The Tesla knockback is essential for surviving the final wave.
The key to victory in the late game is crowd control. Raw damage is not enough when tens of thousands of orcs are rushing your base. Combine slows, knockbacks, and freeze abilities to keep the horde trapped in your damage zones for as long as possible.
