They Are Billions

About

They Are Billions drops you into a resource-scarce wasteland where hordes of infected creatures constantly threaten your last human stronghold. You manage limited supplies to build walls, deploy turrets, and position soldiers while balancing power grids and repair crews. Each wave grows stronger forcing you to adapt defenses in real time. The survival loop focuses on careful planning and quick reflexes as you hold back endless attacks with minimal tools. The game’s stark black-and-white visuals and steampunk-meets-apocalypse vibe create a distinctive look. Its difficulty curve and emphasis on efficiency have earned it a 92% positive rating on Steam. The achievement system adds long-term goals with 34 total rewards including the elusive "Infected Killer Level 10" which only 0.4% of players have unlocked. Most playtime goes toward perfecting base layouts and mastering weapon synergies against unrelenting enemy patterns.
