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 They Are Billions campaign, is the high-mobility, fast-firing alternative to the slower, tankier Caelus. To make her truly effective—especially against dangerous late-game enemies like Harpies—you must prioritize specific stats that offset her naturally low damage. Core Upgrade Priority
Because Calliope depends on kiting (running and gunning), her "best" build focuses on reaching damage and range milestones that prevent enemies from ever touching her.
Attack Damage (Highest Priority): Calliope’s base damage is low. You need at least 33 damage to kill Harpies in 4 shots, which is a critical threshold for surviving late-game tactical missions.
Attack Range: This is essential for kiting. A range of 6+ cells allows you to aggro and potentially kill fast-moving infected before they close the distance. Master the Calliope: How to Build a Better
Movement Speed: While she is already fast, one or two speed upgrades allow her to outrun "Runners" more comfortably, making pixel-hunting for loot much safer.
Loading/Attack Speed: These are secondary. While they help with target switching, many players find that animation cancelling (spamming attack and move) provides more benefit than the actual perks. Essential Strategy & Tactics
Optimizing Calliope: Strategic Build Integration in They Are Billions In the steampunk apocalypse of They Are Billions ,
—the agile, dual-pistol-wielding Hero—serves as the scalpel to Caelus's sledgehammer. To "build better" with Calliope, players must transition from treating her as a standard kiting unit to an elite, high-DPS infiltrator. 1. The Core Philosophy: "Speed is Survival"
Calliope’s primary advantage is her Movement Speed and Attack Rate. Unlike other units, her effectiveness scales exponentially with your ability to micro-manage her positioning.
Kiting Mastery: Use her high movement speed to "weave" between shots. She can outrun almost any standard infected, allowing her to clear large map sections solo without taking damage.
Target Prioritization: Always manual-target Spitters and Harpy units. Her rapid-fire pistols excel at interrupting the attack animations of faster enemies. 2. Skill Tree Prioritization
To build a "better" Calliope, you must focus on her DPS (Damage Per Second) and Utility upgrades within the Empire Campaign. Upgrade Tier Early Game Attack Speed
Increases her "stutter-step" efficiency, allowing more shots per second while kiting. Mid Game Movement Speed
Ensures she can retreat from Executive or Chubby swarms that would otherwise corner her. Late Game Damage & Criticals By late campaign, her damage falls off compared
Necessary to keep her viable against high-armor targets in final swarms. 3. Tactical Synergies
Calliope should rarely fight alone in the late game. A "better build" involves integrating her into a combined arms approach:
The Decoy Maneuver: Use Calliope to pull "aggro" (attention) from a horde, leading them into a kill zone occupied by Soldiers or Snipers.
Point Defense: Pair her with Lucifers. While Lucifers tank and burn the front line, Calliope can pick off the stragglers or fast-moving Harpies that try to jump over your lines. 4. Tactical Errors to Avoid
Static Defending: Never leave Calliope on "Chase" or "Attack Move" in high-density areas. Her low health pool means she will be overwhelmed if she stops moving for more than two seconds.
Ignoring Range: While she is faster than Archers, she has shorter range. Building a better Calliope means respecting the "dead zone"—the space where she is close enough to fire but far enough to turn and run. 5. Tactical Recommendation
For maximum efficiency, focus on Attack Damage upgrades as soon as they become available. Her high fire rate means that even a +2 damage buff results in a massive jump in total damage output per minute.
Are you focusing on Campaign Hero Missions or Survival Mode?
In the grim, steampunk-infested world of They Are Billions, sound is a weapon. The creak of a ranger’s bow, the thunder of a Thanatos rocket, and the haunting melodies of the Empire’s musicians can mean the difference between a thriving colony and 10,000 infected pouring through a single chink in your armor.
No hero unit embodies this delicate balance of utility and risk quite like Calliope, the Mutant Songbird. On paper, she looks like a simple support unit. In practice, she is the single most misunderstood and underutilized asset in the game. If you want to survive the 80-day or 100-day survival mode on 800%+ difficulty, you need to learn how to build better around Calliope.
This guide will break down the mechanics, the meta, and the micro-management required to transform Calliope from a “nice-to-have” distraction into the cornerstone of your apocalypse defense.
