Plan your next They Are Billions session
Our independent guide breaks down the core systems of They Are Billions so you can build resilient colonies, manage resources efficiently, and keep infected hordes at bay without relying on reflex speed.
01 / THE GUIDE
Optimising Energy Layout
Create two colony layouts: one with a central Tesla Tower cluster and another with dispersed towers. Record energy loss and building upgrade speed, then choose the layout that sustains larger armies.
- Secure food and energy early in each mission.
- Research upgrades that improve unit durability.
02 / THE GUIDE
Mercenary Cost‑Benefit Analysis
Track food consumption versus combat effectiveness for three mercenary types over ten in‑game days. Identify which unit offers the best return on resource investment for your current colony size.
- Adapt building layout to the generated terrain.
- Watch weather effects that may affect resource gathering.

03 / THE GUIDE
Pause‑Driven Defense Planning
During a wave, pause repeatedly to map enemy approach vectors. Note how many seconds of pause improve wall placement accuracy and reduce colony breaches.
- Pause to review enemy movement before committing troops.
- Use pause frequently when expanding the colony.
04 / THE GUIDE
Survival Map Adaptation
Generate two random Survival maps with differing terrain. Adjust building placement to each map’s geography and compare survival duration, highlighting terrain‑specific strategies.
- Place Tesla Towers centrally to minimise energy loss.
- Upgrade mills early for a steady food supply.
05 / THE GUIDE
Technology Path Selection
Select three technology branches and simulate their impact on resource gathering, unit strength, and defense. Evaluate which branch aligns best with your preferred strategic approach.
- Balance mercenary costs with food production.
- Mix unit types to cover ranged and melee threats.
