Because Calliope relies on a powerful, high-tech unit (the Banshee), the early game requires discipline. You cannot rush the Banshee immediately.
If you follow this "Build Better" guide, your Calliope at the final mission (The Final Countdown) should look like this:
How to use her in the final wave: Do not put her on the wall. Put her behind the wall, in a second-layer bunker. When the Spitters destroy the first wall, they will flood in. Calliope will fire down the corridor, piercing through 10 zombies per second.
Bottom line: Calliope is an economy and safety multiplier early-mid campaign, not a main army unit. Keep her alive, don’t let her fight hordes, and she’ll let you expand faster.
Master the Calliope: How to Build a Better Hero in They Are Billions
In the steampunk apocalypse of They Are Billions, your hero unit is the tip of the spear. While Caelus offers brute force and Seth provides crowd control, Calliope is the undisputed queen of agility and precision. However, many players struggle to utilize her effectively in the campaign’s tactical missions, often finding her too fragile for the late-game hordes.
If you want to turn this swift assassin into an unstoppable force, you need a specialized strategy. Here is how to create the ultimate Calliope build to dominate every mission. 1. The Core Philosophy: Speed is Survival
Calliope’s primary advantage is her Movement Speed. Unlike other heroes, she can outrun almost every threat in the game, including runners and harpies, if built correctly. A "Better Calliope" isn't just about damage; it’s about ensuring she never gets hit in the first place. 2. Essential Skill Tree Prioritization
To build a better Calliope, you must focus on her strengths: fire rate and mobility. Avoid defensive stats early on; if Calliope is being hit enough to need extra HP, you are playing her wrong.
Attack Speed (Top Priority): Calliope uses dual pistols. Increasing her attack speed exponentially increases her DPS because it applies to both weapons. Maximize this first to shred through "Chubby" infected and small swarms.
Movement Speed: Invest here until you can comfortably kite runners. This allows you to "hit and run"—firing a volley, moving back, and firing again without taking a scratch.
Attack Range: This is the secret to her late-game viability. Increasing her range allows her to pick off Spitters before they can launch their toxic projectiles. 3. Tactical Combat Maneuvers
Building a better hero isn't just about stats; it’s about how you pilot the unit.
The Kiting King: Use the "A" (Attack-Move) key frequently, but manually override it to retreat. Calliope can fire while retreating more effectively than any other unit.
The "Lure and Clear" Technique: Use Calliope’s speed to pull small groups of infected away from a massive horde. Lead them into a chokepoint or a trap, clear them, and repeat. they are billions calliope build better
Targeting Priority: Always set Calliope to "Target Highest Level." You want her dual pistols focused on Executives and Harpies while your backup units (if available) or environmental traps handle the "Slow Joes." 4. Synergy with Empire Points
As you progress through the campaign, use your Empire Points to bolster the technology that supports Calliope.
Mechanical Chimes: Anything that improves unit vision helps Calliope strike first.
Improved Logistics: Faster health regeneration for heroes ensures that even if you make a mistake and take a hit, Calliope is back at 100% for the next room. 5. Avoiding the "Trap" Upgrades
Many players make the mistake of investing in Armor or Melee perks for Calliope. This is a waste of precious skill points. Calliope’s hitbox is small, and her defense is her distance. Every point spent on Armor is a point not spent on Critical Hit Chance, which is where her real "Billions"-slaying power comes from. Final Verdict
The "Better Calliope" build is a glass cannon that relies on the player's micro-management skills. By focusing entirely on Attack Speed, Range, and Critical Hits, you transform her from a simple scout into a whirlwind of lead that can clear entire tactical maps solo.

In the post-apocalyptic strategy game They Are Billions is the fast, dual-pistol-wielding hero specialized in hit-and-run tactics. Building her effectively requires leaning into her agility while mitigating her fragile nature. Strategic Priorities for Calliope
To optimize Calliope, you must prioritize her ability to clear rooms before enemies can close the distance. Her lower health pool compared to Caelus makes "deadly speed" her best defense. Attack Speed is King
: Calliope’s primary strength is her high fire rate. Investing in attack speed early allows her to "stutter-step" (moving between shots) more effectively, keeping her out of reach of slow-moving infected. The Mobility Edge
: She already has superior movement speed. Enhancing this further is not just for convenience; it allows you to kite high-threat enemies like Harpies and Executives around obstacles indefinitely. Range Over Armor
: Because Calliope is easily "two-shotted" by Harpies, increasing her attack range is vital. Killing a threat before it reaches her is always safer than trying to "tank" the hit with armor. The Life vs. Armor Debate : Mathematical analysis of her perk tree suggests that
is consistently better than Armor for Calliope. If you must take a defensive node to reach a damage perk, choose HP to avoid being burst down by sudden spikes in damage. Steam Community Essential Perk Pathing
When leveling Calliope through the campaign, focus on these specific upgrades to maximize her "glass cannon" potential: Damage Nodes How to use her in the final wave:
: Absolute priority. Her low base damage per shot means every point of flat damage significantly reduces the number of bullets required per kill. Grenade Utility
: Grenades are her "panic button." They do not damage Calliope herself, so a common pro-tip is to throw a grenade at your own feet as a Harpy lunges toward you. Vision & Range
: These allow you to clear "fog of war" in tactical missions safely, preventing you from being cornered in tight corridors. Steam Community Tactics for Survival Stutter-Stepping
: Never stand still. Shoot, move back, and shoot again. This maximizes the distance between her and the horde.
: Use her speed to pull small groups of infected away from larger swarms. The Harpy Counter
: Harpies are her greatest threat. If you cannot kill them at range, use a medkit immediately after the first hit or pre-fire a grenade in their path.

Hero and Perk test results :: They Are Billions General Discussions
Here’s a write-up focused on the Calliope and how to build better, more resilient colonies around her unique strengths in They Are Billions.
The Calliope’s genius lies in its high rate of fire and surprisingly low energy cost. Firing multiple projectiles in quick succession, it excels at “crowd suppression”—shredding the health of dozens of infected simultaneously rather than killing one at a time. When paired with a single layer of wooden wall, a single Calliope can hold a chokepoint against early wave compositions that would overwhelm two Ballistae. Its sound profile, while notable, is no louder than a Ballista’s thrum, and its rapid hits stagger and slow advancing enemies, buying precious seconds for repair or ranger support.
More importantly, the Calliope enables a distributed defense network. Because it costs roughly the same stone and wood as a Ballista but requires less gold upkeep, players can place three Calliopes at key angles instead of two Ballistae. This redundancy is life-saving during surprise attacks from undetected directions. Furthermore, the Calliope’s compact footprint allows it to be squeezed between housing blocks or behind double-layered walls, creating overlapping fields of fire that a Ballista’s narrow arc cannot match.
In campaign missions with ruins (buildings), hide Calliope inside a destroyed doorway. The pathfinding in They Are Billions will make zombies crowd the single tile entrance. Place Calliope 2 tiles back. She will shoot through the doorway, piercing the entire crowd.
The standard meta often prioritizes the Ballista for its high single-shot damage and wooden construction. Yet, the Ballista suffers from two fatal flaws: overkill and slow rate of fire. When facing a runner-heavy wave, a Ballista will obliterate one infected per second, leaving the remaining dozen to breach the walls. The Shocking Tower, while devastating against dense clusters, requires advanced workshops, significant energy, and gold upkeep—luxuries that are scarce during the critical days 20–40. Reliance on these tools often breeds a passive playstyle: build a static defense, wait, and hope.
This is where the conventional wisdom fails. The infected do not wait, and they do not come in neat, single-file lines. They pour through forest gaps, flank around chokepoints, and swarm from random raid directions. A build that relies on slow, heavy-hitting defenses is a build that reacts to disaster rather than preventing it. A better strategy demands a tool that can pivot, suppress, and saturate.
