Optimizing Your Calliope Build in They Are Billions

The Calliope is a powerful defensive structure in They Are Billions, capable of decimating hordes of zombies with its high damage output. However, building an effective Calliope defense requires careful planning and strategy. Here are some tips to help you build a better Calliope:

Choose the right location: Place your Calliope in a strategic location that provides a clear line of sight to the zombies and is protected from flanking maneuvers.
Upgrade your Calliope: Upgrade your Calliope to increase its damage output and range. Focus on upgrading the damage and range upgrades first.
Add supporting structures: Build supporting structures such as Watchtowers and Machine Guns to provide additional damage and crowd control.
Use the right ammo: Use the right ammo type for the job. For example, explosive ammo is effective against hordes of zombies, while armor-piercing ammo is better against tougher zombies.
Keep your Calliope maintained: Regularly maintain your Calliope by repairing it and upgrading its components.

Some popular Calliope build strategies include:

The Calliope Tower: Build a tower of Calliopes to create a powerful defensive line.
The Calliope Wall: Build a wall of Calliopes to create a barrier against zombies.
The Calliope Ambush: Build a Calliope in a hidden location and ambush zombies as they pass by.

By following these tips and strategies, you can build a more effective Calliope defense and protect your colony from the zombie hordes.

Example Build:

1x Calliope (upgraded to max damage and range)
2x Watchtowers (upgraded to max damage and range)
1x Machine Gun (upgraded to max damage and range)
1x Ammo Box (with explosive ammo)

Tips and Variations:

Experiment with different ammo types and upgrades to find the best combination for your playstyle.
Add additional supporting structures such as Turrets or Mortars to provide additional damage and crowd control.
Use the Calliope's area of effect damage to take out multiple zombies at once.

The Concept

Because Calliope slows enemies by 30% passively, she creates a "sticky zone" around her. You can build houses outside your main perimeter if you place her correctly.

How to execute (Days 8-15):

Find a natural choke point (two trees, rocks, or a pond) roughly 15 tiles away from your Command Center.
Build a single Wooden Wall in a "V" shape at the choke.
Place Calliope directly behind the wall, set to Hold Position (Do not use "Chase").
Build 8-10 Tents in a semi-circle behind Calliope.

Why this works: When a stray infected (Walker/Runner) approaches the houses, Calliope’s slow aura triggers before they reach the first tent. Her high damage one-shots Walkers. Because she doesn't move, she rarely fires faster than her 2.1-second cooldown, keeping the noise profile just below the threshold that triggers a swarm.

The Build Order:

Day 1-5: Standard 2x Ranger, 1x Soldier Center.
Day 6: Acquire Calliope from the Inn (Priority #1).
Day 7-10: Execute the Vampire Box. This gives you a +200 gold/tick income without spending resources on 5 wooden towers.

This is how you build better – leveraging her passive to skip early defense towers and funnel resources into a Workshop and Stone Tech.

The "Pocket" Formation

Instead of long, straight walls, create "pockets" or "lobster pots." they are billions calliope build better

Build a wall with a gap.
Place a Tesla Tower just behind the gap.
Position the Banshee behind the Tesla Tower.

The infected will funnel through the gap, clumping up perfectly for the Banshee’s AoE attack. Because the Banshee has range, it can hit the clump before they breach the wall.

Excellent Missions (Use Calliope):

The Narrow Passages (Cape Storm, Mines of the Damned): Her piercing shot is king in choke points. Line her up so zombies stack in a queue.
Swamp Biomes: Spitters are abundant here. Her high attack speed allows her to stun-lock Spitters (yes, hits cause flinch).
Swarm Missions: Never use Calliope alone in open field swarms. Pair her with a line of soldiers. She acts as the "commander unit" to kill Fat Zombies quickly.

Operational Tips

Manage resources: Ensure a steady supply of resources to maintain and upgrade your Calliope.
Monitor zombie hordes: Keep an eye on zombie hordes and adjust your Calliope's position or add additional defenses as needed.
Upgrade and adapt: Continuously upgrade your Calliope and supporting structures to adapt to changing zombie threats.

Optimization Tips

Use Calliope's terrain: Position your Calliope on a raised surface to increase its range and visibility.
Create a kill zone: Design your base to create a kill zone, funneling zombies into the Calliope's line of fire.
Diversify defenses: Mix and match different defensive structures to create a well-rounded defense.

By following this guide, you'll be well on your way to building a formidable Calliope that can protect your base from even the most determined zombie hordes. Happy building!

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

: 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 Optimizing Your Calliope Build in They Are Billions

: 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

They Are Billions , the Calliope hero mission is often a polarizing experience for players. While some find her agility a breath of fresh air, others struggle with her lack of raw power compared to Caelus. To make Calliope truly "solid," you have to lean into her role as a high-precision, tactical skirmisher rather than a frontline tank.

Here is an analysis of how to build Calliope to dominate the campaign. The Philosophy: Speed as Armor

Calliope’s greatest asset is her movement speed. Unlike Caelus, who stands his ground, Calliope is designed for "kiting"—the act of shooting and moving before the enemy can swing. A solid build prioritizes her ability to clear rooms without taking a single hit, using her high rate of fire to stun-lock small groups. Key Upgrade Path

To make her viable in the mid-to-late game, your skill points should be allocated in this priority: Attack Speed & Reload: Choose the right location : Place your Calliope

This is her "DPS" floor. Calliope relies on volume. Because her individual shots deal less damage than Caelus, she needs to fire fast enough to prevent "runners" from reaching her. Movement Speed:

Doubling down on her natural gift allows her to outrun almost everything in the game. This turns her into an elite scout who can trigger a pack of zombies, lead them into a choke point, and escape unscathed. Critical Hit Chance:

Since her base damage is low, "Crits" are the only way she can effectively take down "Executives" or "Chubbies" in tactical missions. A high-crit Calliope becomes a surgical tool that can occasionally one-shot medium threats. Tactical Application

In the field, a solid Calliope build changes how you play tactical missions: The Hit-and-Run:

Use her to "peek" into rooms. If the room is packed, fire a few shots to aggro the front line, then retreat to a narrow hallway. Her speed ensures she stays just out of reach while her fast fire rate thins the herd. Grenade Management:

Since Calliope lacks Caelus’s innate AoE, her grenades are her "Oh Crap" button. Save them strictly for when you are cornered or facing a massive swarm of "Harpy" variants. The Verdict

Calliope isn't meant to be a wall; she’s a scalpel. A solid build focuses on Attack Speed

, transforming her from a weak scout into a rapid-fire assassin. By the time you reach the late-game missions, a fully upgraded Calliope can clear entire sectors of the map solo, provided the player has the micro-management skills to keep her moving. best missions to tackle first to unlock her key upgrades quickly?

I’ll create a concise feature proposal to improve Calliope (the campaign/hero) in They Are Billions. I’ll assume you mean the playable hero/unit “Calliope” (magical/utility support archetype). If you meant something else, say so.

The Door Frame Trick

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.
