They Are Billions Calliope Build ((exclusive)) May 2026

Here’s a solid, concise guide for a Calliope build in They Are Billions (Survival mode, max difficulty-friendly):

Calliope Build – “The Crit Commander”

Core Focus: High burst damage, early wave clear, and economy snowball via critical hits.

Tech Priority (First 10 days):

Wood Workshop → Farm + Sniper (skip Soldier)
Stone Workshop → Ballista + Market
Foundry → Lucifer (if map allows) OR Engineering Center → Shocking Tower
Optional late game: Titan + Thanatos for final wave, but Calliope can carry with mass Snipers + Lucifers.

Calliope’s Major Pick (Level 2+):

Take “Deadshot” (+50% crit damage to Snipers) – this is non-negotiable.
→ Snipers become 1-shot killers for Harpies, Spitters, even Chubbies with 3-4 hits.

Secondary Mutations (per run):

“Swift Attack” (attack speed after kill) → excellent for defending mini-waves.
“Resourceful” (extra gold/wood per kill) → speeds up early expansion.
“Reinforced Ammo” (pierce chance) → turns Snipers into mini-Executors.

Build Order:

Day 0–4: 10 Rangers → secure food + wood.
Day 5–7: Pump Snipers (aim for 15–20 by first spitter wave).
Day 10–15: Ballista at every choke + double Sniper production.
Day 20–30: 60+ Snipers, 3–4 Lucifers or Shocking Towers for crowd control.
Day 30+: Add Thanatos (1 per entrance) + walls ×4 thick.

Final Wave Setup:

Calliope + 80 Snipers (all on “Highest Level” targeting) behind double stone walls.
Lucifers at chokepoint corners to melt zombies clumping.
Keep her mobile – her crit aura is small; reposition during final wave to reinforce the busiest gate.

Pro tip: Don’t take “Frenzy” (increased attack speed but reduced range) on her – Snipers lose their range advantage and die to Spitters. Stick to crit/damage buffs only.

Building Calliope in They Are Billions: A Comprehensive Guide

In the popular real-time strategy game They Are Billions, Calliope is a crucial defensive structure that can make or break your colony's survival. As one of the most powerful artillery units in the game, Calliope provides unparalleled protection against the hordes of infected humans and other threats that seek to destroy your settlement. In this guide, we'll walk you through the process of building Calliope and provide you with valuable tips and strategies to maximize its effectiveness.

Prerequisites for Building Calliope

Before you can start building Calliope, you need to meet certain prerequisites. Firstly, you need to have a sufficient amount of resources, including gold, steel, and oil. The exact resource costs may vary depending on the game's balance and your current level of technology.

Secondly, you need to have a Workshop, which is a fundamental building that allows you to research and construct more advanced structures and units. Make sure you have a steady supply of raw materials and a skilled workforce to construct and maintain your buildings.

Lastly, you need to research the Calliope technology in the Research Tree. This will unlock the blueprint for building Calliope and allow you to start constructing it.

Building Calliope

Once you've met the prerequisites, you can start building Calliope. To do this, follow these steps:

Open your Building Menu and navigate to the Defensive Structures section.
Find the Calliope blueprint and click on it to select it.
Choose a suitable location for your Calliope, taking into account its range, line of sight, and proximity to your colony.
Confirm the construction by clicking on the "Build" button.

Optimizing Calliope's Placement

The placement of Calliope is critical to its effectiveness. Here are some tips to keep in mind:

Position Calliope at a high point: Calliope's elevation can significantly impact its range and line of sight. Try to build it on a high point or a hill to maximize its visibility and firing range.
Place Calliope near your colony: Calliope's primary function is to defend your colony, so it's essential to build it near your settlement. This will allow it to respond quickly to threats and protect your people and resources.
Avoid building Calliope in a narrow corridor: While Calliope is an excellent defensive structure, it's not designed to handle enemies that attack from multiple angles. Avoid building it in narrow corridors or bottlenecks, as this can make it vulnerable to flanking.

Upgrading and Maintaining Calliope

Once you've built Calliope, it's essential to upgrade and maintain it regularly. Here are some tips:

Upgrade Calliope's damage and range: As you progress through the game, you'll encounter more formidable enemies that require increased firepower to defeat. Upgrade Calliope's damage and range to stay ahead of the threats.
Keep Calliope fueled: Calliope requires a steady supply of fuel to operate. Make sure you have a reliable source of fuel and maintain a sufficient stockpile to keep it running.
Protect Calliope from damage: Calliope is a critical defensive structure, and its loss can be devastating. Make sure to protect it from damage by placing other defensive structures around it or assigning a guard unit to defend it.

Tips and Strategies

Here are some additional tips and strategies to get the most out of Calliope: they are billions calliope build

Combine Calliope with other defensive structures: Calliope is more effective when combined with other defensive structures, such as Machine Guns, Mortars, or Shot Towers. Experiment with different combinations to find the optimal defensive setup.
Use Calliope to anchor your defensive line: Calliope's long-range firepower makes it an excellent anchor for your defensive line. Use it to pin down enemies while your other defensive structures pick them off.
Keep an eye on Calliope's ammo: Calliope has limited ammo, so make sure to keep an eye on its ammo levels and replenish them as needed.

By following these tips and strategies, you can build and maintain an effective Calliope defense that will protect your colony from even the most formidable threats. Happy building!

They Are Billions is the agile, "hit-and-run" hero choice for the campaign's tactical missions. Unlike her counterpart Caelus, who functions as a slow, tanky AOE powerhouse, Calliope relies on movement speed rapid fire to kite enemies. Calliope "Glass Cannon" Build Guide

To maximize her effectiveness, you should prioritize damage and utility over survivability, as her kiting ability means she should rarely take hits. Primary Focus: Damage & Fire Rate Damage Nodes:

Vital for reducing the number of shots required for high-threat targets like Harpies and Venoms. A common goal is reaching damage to 4-shot Harpies. Attack/Load Speed: Investing in at least

load speed significantly reduces the need for manual animation cancelling, making her much smoother to play. Secondary Focus: Range & Speed Increasing her range to around

allows her to engage and retreat before fast enemies can close the gap. Movement Speed:

While she is already fast, extra speed ensures she can outpace even the quickest infected. Utility & Defense Health over Armor:

If you must take defensive perks to reach further damage nodes,

is mathematically superior to Armor in almost all cases for her limited perk slots.

These are essential for clearing rooms packed with low-level infected or handling sudden rushes. Review: Tactical Hero Missions

The community consensus on Calliope and the tactical mission system is polarizing. Dynamic Gameplay:

Her high speed makes kiting feel rewarding and skill-based compared to the slower, stationary defense of traditional RTS missions. Resource Gains:

These missions are the primary way to secure massive amounts of Research Points Empire Points , which are critical for colony tech progression. Pacing Issues:

Many players find the tactical missions slow and repetitive compared to the core base-building gameplay. Difficulty Spikes:

On higher difficulties (like 200%+), a single mistake can lead to Calliope being "2-shot" by Harpies, forcing a mission restart. Visual Fatigue:

Some players report that hunting for tiny, pixel-sized collectibles (like documents) for research points can become tedious. Are you stuck on a specific mission

(like The Foundry or The Last Bunker), or do you want advice on which colony technologies to research next?

The sky over the colony of New Hope wasn’t blue; it was the color of rusted iron, choked by the eternal smog of the Great Infection. High atop the western ramparts, Calliope checked the tension on her composite bow. She wasn’t like the hulking Soldiers or the soot-covered Snipers. She was a shadow given form, the ultimate expression of the Empire's "Quiet Death" initiative.

"The swarm is four miles out," a scout radioed, his voice trembling. "It’s a Tier 4. Harpies included."

Calliope didn’t blink. She looked down at the Shock Towers humming below her. The Mayor had spent weeks pouring every ounce of gold and wood into her specific training—the Calliope Build. It was a gamble. Instead of a massive wall of fire and lead, the colony relied on her inhuman speed and a specialized grid of Tesla Towers designed to funnel the dead into a narrow "kill box."

As the first wave of runners emerged from the fog, Calliope leaped. She didn't stay on the walls. Using her Agility Perk, she vaulted over the spiked barricades, landing silently in the dirt.

To the untrained eye, she was a blur. She moved in a rhythmic dance, her arrows finding eyes and throats with surgical precision. She wasn't just killing; she was kiting. With every shot, she drew thousands of infected away from the fragile wooden gates and toward the electrified "death corridor."

The Harpies screeched, diving from the clouds. Calliope performed a mid-air twist, releasing three arrows in a single heartbeat. The winged horrors tumbled, pinned to the earth. But the sheer volume of the horde was stifling. The ground shook as a Giant crested the hill, its rotting flesh pulsating. "Now!" Calliope signaled. Here’s a solid, concise guide for a Calliope

The colony's Lucifers opened their fuel valves, but not to spray the front. They created a ring of fire behind Calliope, sealing her in with the horde. It looked like a suicide mission, but it was the final piece of the strategy.

Trapped between the fire and the dead, Calliope’s Veteran Status kicked in. Her attack speed doubled. She became a whirlwind of obsidian glass and carbon fiber. As the Giant lunged, she slid between its massive, decaying legs, planting a high-explosive canister—a gift from the Engineering Center—into its heel.

A deafening roar preceded the explosion. As the Giant fell, it crushed hundreds of lesser undead, creating a temporary ramp. Calliope sprinted up the monster’s back and vaulted back onto the colony walls just as the Shock Towers unleashed a localized storm of blue lightning, vaporizing the remaining thousands.

Silence returned to New Hope, save for the crackle of burning ozone. Calliope wiped a smudge of black blood from her cheek and sheathed her bow. She had held the line. They were billions, but tonight, she was the only one that mattered.

In the They Are Billions campaign, Calliope is a high-speed, agile hero who excels at kiting and tactical speed-clearing. To maximize her potential, a "Glass Cannon" build focusing on Range and Damage is widely considered the most effective for surviving late-game threats like Harpies. Core Build Strategy: The Kiting Specialist

Calliope's primary strength is her mobility, which allows her to outrun almost any enemy. Your goal is to kill high-threat targets before they ever reach her.

Priority 1: Attack Range & View RangeIncreasing her range is critical for engaging Harpies and Spitters from a safe distance. At a high enough level, Calliope can kill Harpies before they trigger their sprint if you aggro them from max range.

Priority 2: Attack DamageYou need enough damage to "one-shot" runners and "four-shot" Harpies. Aim for perks like Aim IV (+50% Attack Damage) to ensure she clears rooms efficiently without getting overwhelmed.

Priority 3: Attack & Reload SpeedWhile kiting, attack speed allows her to fire more shots while moving. Her base attack speed is already high (5.0), and perks can push this significantly higher.

Defensive Utility: Health over ArmorIf you must choose a defensive path to progress the skill tree, prioritize Life/Strength (+30% or +50% Life) over Armor. Math-wise, increased HP is more effective than Armor perks for surviving accidental hits. Key Perks to Target Perk Name Importance Improved Vision III +1 View Range, +1 Attack Range Essential for elite enemies. Aim IV +50% Attack Damage Essential for clearing power. Quick Reflexes II +40% Loading Weapon Speed High value for faster firing cycles. Speed I +20% Movement Speed Useful for kiting, though her base speed is already decent. Operational Tips

They Are Billions , is the "fast and agile" hero choice for tactical missions, serving as a high-speed alternative to the heavy-hitting but slow Caelus. Calliope Build Review & Key Stats

Calliope excels at kiting—the practice of moving and firing to stay out of reach of enemies—which makes her superior for clearing large, open areas where movement is critical.

Weaponry: She uses "The Devil’s Sisters," dual pistols that have a high fire rate and fast reload but suffer from low base damage and short range.

Pros: Her high movement speed allows her to outrun almost anything on the map and complete tedious search-and-find objectives faster.

Cons: She is extremely fragile. Without the right upgrades, she can be two-shotted by Harpies in later hero missions. Recommended Optimal Build Strategy

Reviewers from the Steam Community and Reddit generally agree that a "Glass Cannon" damage and range build is the most effective.

Mastery Guide: The Ultimate Calliope Build for They Are Billions is one of two heroes available in the They Are Billions

"New Empire" campaign. Known for her rapid-fire pistols, "The Devil’s Sisters," she excels in mobility and kiting Calliope Build – “The Crit Commander” Core Focus:

, making her a preferred choice for players who value speed and micro-management over raw tanking. Core Attributes & Role

Unlike the heavy-hitting Caelus, Calliope is built for speed. Her base stats feature lower health and short-range attacks, but her high movement speed allows her to outrun almost any enemy except Harpies. The Optimal Build Path (Perks)

Calliope’s upgrade tree branches out from four central perks. To make her viable at higher difficulties (like 500% or 800%), you must prioritize damage and range to counter her natural weaknesses. 1. Essential Offensive Upgrades Attack Range (Improved Vision I & II):

This is your top priority. Calliope’s base range is short, often pulling her into dangerous territory. Increasing range allows you to "aggro" enemies from afar and start kiting earlier. Attack Damage (Aim I-IV):

Essential for reducing the number of shots required per kill. For example, without damage upgrades, runners can take 4 shots to kill, which is lethal in swarms. Attack Speed (Dexterity I-III):

This synergizes with her rapid-fire pistols, allowing her to "mow down" runners more efficiently. 2. Survivability: The "Harpy" Threshold

Harpies are the primary threat to Calliope, as they can close the gap faster than she can run. They Are Billions Campaign Guide 500% - Steam Community
