Reviews
They Are Billions is a strategy game that spends hours letting you build a thriving colony, then sends fifty thousand zombies to inspect your construction quality. The early game is all about expansion, resource management, and carefully securing territory. Every wall, tower, and defensive position matters because a single infected slipping through your defenses can trigger a disaster that spreads through your colony in seconds. The tension never disappears. Even when your settlement looks unstoppable, you are constantly preparing for the next wave. Watching thousands of infected crash into carefully designed fortifications is both terrifying and incredibly satisfying. The steampunk setting, varied units, and technology progression provide plenty of strategic options. Rangers, snipers, soldiers, and powerful late-game weapons each have a role, and deciding how aggressively to expand is often the difference between victory and total collapse. The campaign can feel repetitive, some missions drag on longer than necessary, and losing after several hours due to one mistake can be painful. However, that pressure is exactly what makes success so rewarding. Everything was perfectly defended. Then one zombie found a gap I didn't know existed, and suddenly my entire population became part of the problem.

地图都清完,丧尸也会从边缘出来掏你一把,巡逻也没用,弱智AI
智障吧?都有兵在巡逻也能被冲进来,傻逼吧
I feel insulted by the bunker mission. It was the most boring thing I've ever played. Who designed that? Seriously, this is the first time a mission in a game has been so unbelievably boring that I uninstalled a game that was otherwise pretty good.
很好玩,可惜听说制作组跑路了,唯一觉得就是可能不更新了,内容好少,以及尸潮来了只说了方向,但是你不知道从哪个口子来,这样调兵很容易来不及。
제대로 안 알아보고 산 내가 잘못이지 타워디펜스쪽에 가까운줄 알았는데 RTS 그 자체네
Tried to pick up this game multiple times. Its such a slog. The forced Iron man mode should be a choice not forced. The top negative review is very accurate. Losing a 3 hour session because one zombie in the fog of war destoyed your hunters hut or your tent (which you have to build a million of them) is....not fun. WHY are the track running thru the middle of your camp preventing you from building good defences? WHY does it start you in the middle of the map which is always the worst spot? Like I really want to like this game but it could have just been made... better. Dont get me started on the skill tree. Just skip this one. much more fun rewarding less wanting to pull your hair out RTS titles

I love having 1 single infected slip by all my units ending my entire hour long runs.
