This level of customization is one of They Are Billions' biggest and earliest strengths and enough to inspire some initial excitement. The difficulty of the game depends on settings players can adjust before the game begins, like the amount of days before the horde arrives and the amount of the population infected. Set in the late 22nd century and featuring more than a healthy dose of steampunk and zombies, the title tasks players with building up their settlement within a certain amount of days before the big horde arrives and attacks. They Are Billions, like most strategy games of its kind, uses a top-down view of the map, which is randomly generated when the player starts up a new game. While this is enough to make They Are Billions feel refreshing, its lack of variety in game modes and flimsy controls make for a somewhat frustrating experience overall.

Its setting in a steampunk-inspired world is a nice change of pace from the usual medieval-like settings that populate strategy games. They Are Billions, a zombie survival real-time strategy game by Numantian Games, takes its mish-mash of different genres to thoroughly enjoyable heights, even if it never really knocks any of them out of the park. Numantian Games' They Are Billions is an enjoyable enough survival strategy game that's hampered by a lack of variety and poor controls on Xbox One.
