Reviews
Devs are scum. They don't take any kind of criticism and proceed to lock or delete discussion threads. They've spent many years working on a Campaign Mode nobody wanted instead of adding more content or QoL updates to the exquisite Survival Mode (we all love it). Also, many years ago, there was a thread about a bug where one of your tents would start spawning zombinos out of nowhere. It wasn't a bug; it was an "evil" early-build uploaded by the devs on pirate sites. That's just pitiful. Absolute retarded devs!!
Интерфейс ужасен, просто ужас, за такую цену можно было сделать лучше, прям злость берет. Игра не новая, могли бы сделать ребилд интерфейса, но нет! Мы не будет. Просто минус

A fantastic and addictive strategy game! They Are Billions is one of the most satisfying survival strategy games I've played. The combination of city building, resource management, exploration, and defending against enormous zombie hordes creates a genuinely tense and rewarding experience. I especially love how every decision matters. Expanding too quickly can leave your colony vulnerable, while playing too defensively can prevent you from getting the resources you need. The constant pressure of preparing for the next wave keeps the gameplay exciting from start to finish. Watching thousands of infected crash against carefully planned defenses is incredibly satisfying, and the steampunk atmosphere fits the game perfectly. The difficulty can be brutal, but overcoming a seemingly impossible situation makes victory feel genuinely earned. If you enjoy RTS, base-building, tower defense, or challenging survival games, They Are Billions is absolutely worth playing. Highly recommended!
Отличная стратегия с гибкой сложностью.
Goated ass game, highly recommend to anyone who plays command & conquer
蒸汽朋克风末日生存 RTS,融合城建经营与硬核塔防。你需要扩张领地、构筑防线,抵御铺天盖地的尸潮。一处防线疏漏、单个感染者闯入,便足以让苦心经营的殖民地瞬间覆灭。游戏紧张感十足,但单位 AI 略有缺陷,单局耗时漫长。适合喜爱长线经营、追求极限防守挑战的策略玩家。
Crazy to not have alerts on for when zombies attack your buildings. Unplayable missions.
