They Are Billions offers an almost perfect gameplay loop, mixing tower-defence with city building and exploration, as you balance resource-management, defence and offense, all against your ever-impending doom at the hands of a world infested with the undead. The only downside to a game that looks and sounds great, offering a tense experience in a compelling setting, is a campaign that doesn't fully make-use of the gameplay loop perfected by Numantian Games, leaving the campaign feeling weak, compared to the survival mode, which is the real draw.

They Are Billions remains a tight and compelling strategy game. The knowledge that you're always just one misstep away from disaster creates a gripping, tense atmosphere that's unusual for the genre. And the cycle from defense to offense and back again as you progress from one wave to the next offers both well-paced urgency and the ability to set clear short-term goals. It's a smartly designed game at its core. It just needed to realize that sometimes that's enough.

They Are Billions is a brilliant game that breaths fresh life into the RTS formula. Its setting, concept, and execution make it a wonderful addition to the genre. However, the console port with poor controls will most likely leave players frustrated and wishing they had picked it up on PC. As much as I loved the title I cannot recommend it for a console. So if you’re interested in They are Billions I would strongly recommend taking a look at the PC version of this zombie survival RTS.
