is the agile, high-speed alternative to the lumbering Caelus. While she has lower health and damage per shot, her ability to kite and fire rapidly makes her a lethal asset for tactical missions when built correctly. Core Character Stats Health: 60 HP (Low, requires careful positioning). Attack Range: 4.5 tiles. Attack Speed: 5.0 (Base). Movement Speed: 3.2 (Fastest hero). Recommended Skill Tree Priorities

To maximize Calliope’s potential, focus on Damage breakpoints and Attack Speed rather than survival stats. Damage & Range (High Priority):

Invest in at least three damage upgrades (+30%, +40%, +50%) to reach approximately 33 damage. This allows Calliope to kill Harpies in exactly 4 shots.

Maxing her range to 6.5 is critical for engaging enemies before they can close the gap, potentially making HP/Armor upgrades redundant. Attack & Reload Speed:

Reload Speed: A single point in +40% load speed significantly reduces re-targeting animations, making "kiting" much smoother.

Attack Speed: Multiple perks can boost her speed to nearly 3x her base, allowing her to shred through crowds of runners. Utility & Survival:

Movement Speed: Already her greatest strength; one point is usually enough to maintain a safe distance from most infected.

Noise Reduction: Generally considered underwhelming; specialized players prefer killing enemies quickly over being stealthy. Tactical Mission Strategy

Run and Gun: Utilize her superior movement speed to "kite" hordes. Fire a few shots, move back, and repeat. they are billions calliope build new

Animation Canceling: You can ignore reload times by issuing a new attack command immediately after a shot, a trick that works particularly well with Calliope’s rapid pistols.

Harpy Engagement: Always aggro Harpies at max range (6+ cells). If they get too close, rely on grenades or medkits rather than trying to tank the damage. Late-Game Viability

In high-difficulty 800%+ runs, a fully upgraded Calliope becomes a "Valkyrie," often accompanied by veteran Rangers in tactical missions. While Caelus excels at stationary defense with AOE, Calliope is the superior choice for players who prefer a proactive, micro-intensive playstyle to clear maps.

If you're jumping back into the They Are Billions campaign, building a high-tier

is all about leaning into her role as a high-speed kiter. Unlike the tanky Caelus, Calliope is a "glass cannon" who needs to avoid hits entirely by staying mobile. ⚡ Core Build Priorities

Since you only get 9 total points across the tactical missions, you must prioritize stats that let you clear rooms without taking damage.

Range & Damage (Critical): Invest heavily in Aim and Improved Vision. Getting her attack range to 6+ cells allows you to aggro and kill dangerous units like Harpies before they reach you.

Attack Speed: Calliope’s base attack speed is already high, but adding Dexterity perks makes her lethal against swarms.

Health over Armor: If you need survivability, pick life upgrades over armor. Armor provides zero defense against non-standard damage like fire or venom. The Ultimate Calliope Build Guide: Mastering the "Devil’s

Movement Speed: While she's naturally fast, a single point in Speed can be a literal lifesaver when kiting Harpies or sprinting to the exit in a pinch. 🎮 Expert Kiting Strategies

In the They Are Billions campaign, is the high-mobility, high-risk "assassin" hero compared to Caelus’s tanky, slow-firing style. While she starts with low damage and short range, a "new" and optimized build focuses on achieving specific breakpoints that allow her to clear tactical missions—especially those with Harpies—without taking a single scratch. The "Harpy-Slayer" Core Build

To make Calliope viable at higher difficulties (500%–800%), you must prioritize range and damage to hit the "4-shot Harpy" breakpoint. Priority 1: Attack Damage (Aim Perks)

Invest in at least three damage upgrades (+30%, +40%, and +50%) to reach roughly 33 damage.

Goal: This allows Calliope to kill a Harpy in exactly 4 shots after damage reduction, often before they can close the gap. Priority 2: Range (Improved Vision) Unlock Improved Vision III (+1 Range) early.

Goal: Kiting is your lifeblood. Reaching a range of 6.5+ cells ensures you can aggro elites at a safe distance and fire enough rounds to kill them while backpedaling.

Priority 3: Attack Speed & Reloading (Dexterity/Quick Reflexes)

Pick up at least one Attack Speed (+20%) and one Reload Speed (+40%) perk.

Goal: Faster reload times reduce the "stutter" in your kiting, making it harder for runners to catch you between shots. Essential Support Perks Day 5 – Military Entrance

Once your damage is stabilized, these "utility" picks ensure survival if a mistake happens:

Protection I & Strength II: Just one point in each (Armor +15% and Life +30%) allows Calliope to survive up to 3 hits from a Harpy rather than dying instantly.

Speed I: While she is naturally fast, a single speed perk ensures she can outrun literally anything on the map, including Harpies when kiting. Advanced Tactical Tips

Animation Skipping: You can kill zombies 2–3x faster by clicking a new target the instant Calliope fires her last shot. This "microing" skips the reload animation and is essential for clearing the Foundry or Medical Center on Apocalypse difficulty.

The "Feet Grenade": Harpies are faster than Calliope. When they agro, run away, wait for them to start their attack animation, then drop a grenade at your own feet while continuing to move. The delay on the blast will catch the Harpy right as it reaches the spot you just left.

Stealth vs. Aggro: While Calliope has noise reduction perks, they are often considered less efficient than raw damage. High-level play typically involves clearing maps by intentionally pulling small groups and kiting them back to cleared rooms. Calliope | They Are Billions Wiki | Fandom

4. Common Mistakes & Corrections

| Mistake | Calliope Fix | |---------|---------------| | Building too many Rangers | Stop at 4. Train Soldiers after Day 5. | | Expanding before walls | No outer building until a Wood Gate is placed. | | Researching Logistics first | Research Farming first (food = more Cottages = gold). | | Ignoring energy cap | Build Windmill on Day 4 exactly, not earlier. |

Day 5 – Military Entrance

  • Immediately build Soldier Center – do not wait for more resources. Pause if necessary.
  • Queue 2 Soldiers (not Rangers) – they are your early wave clearers.
  • Build first Wooden Gate & Wall segment at the primary infected approach.

Day 6 – First Wave Prep

  • By start of Day 6, you should have:
    • 6+ Cottages, 2 Sawmills, 1 Quarry, 1 Windmill
    • 4 Rangers, 2 Soldiers (with 1 more queued)
    • Wood Workshop + Farming researched
  • Begin placing first Farm (food for expansion).
  • Position 1 Soldier + 1 Ranger at each of the two most likely approach vectors.

4. Economic & Tech Path

  • Prerequisites: Heavy Industry/Advanced Workshop and required research (assumed prerequisites similar to in-game).
  • Resource investment: High wood/stone/iron/gold footprint — build only after stable economy (≥200 population housing, steady resource income).
  • Recommended timing: Start Calliope production in early to mid-game (day ~200–300) once walls and primary defenses are established and surplus workers exist.
  • Production cadence: 1–3 Calliopes for defense; up to 5–7 for coordinated offensives on large maps or late-game exterminations.

Abstract

This paper analyzes a novel build order and strategic role for the Calliope unit in They Are Billions (post-2024 balance context assumed). It outlines unit strengths/weaknesses, optimal tech path, economy and base layout integration, tactical use in offensive and defensive phases, counters, and suggested micro and macro considerations. The goal is a reproducible, high-win-rate approach for mid-to-late game survival.
