Our Take

If you're into strategy games and handling massive zombie hordes, $29.99 isn't bad. But if you expect groundbreaking innovation, you might want to wait for a sale.

Review

They Are Billions offers a unique twist by setting its strategy mechanics in a post-apocalyptic world full of zombies. The ability to pause in the middle of intense battles is great for strategists who prefer to think rather than click frantically. However, facing off against thousands of infected at once can be daunting, and some might find the gameplay loop repetitive over time. The game stands out with its custom engine that manages massive swarms of enemies effectively, creating a sense of urgency unlike many strategy games. Visually it promises a beautiful Steampunk world, although its animation claims might not impress everyone equally. The price tag of $29.99 feels reasonable given its depth, though not necessarily enticing for those on the fence.

Pros

  • +Lots of missions in the campaign mode
  • +Survival mode with weekly challenges
  • +Real-time strategy with pause feature

Cons

  • -Can get overwhelming with thousands of units
  • -Might be repetitive with similar mechanics
  • -Price might be high for some players

Gameplay

Build and manage colonies post-zombie apocalypse. Campaign mode lets you fight for reconquest through various mission types. Survival mode challenges you to maintain a colony under constant threat for 100 days.

On Switch 2

Being a Switch 2 exclusive, it's expected to run smoothly, but there's no data on specifics yet. The platform should handle the scale of the swarms well.

Who It's For

Strategists who love managing colonies and aren't afraid of thousands of zombies on screen.

About

Billions of infected roam around the world in massive swarms seeking the last living human colonies.Game ModesCampaign In the campaign mode, you have to help the surviving humans to reconquer their country. There are dozens of missions with different goals: building colonies, tactical missions, rescue missions... You can decide the path of progress and mission - research new technologies, advances and upgrades to improve your colonies and army. Survival Mode In this mode, a random world is generated with its own events, weather, geography, and infected population. You must build a successful colony that must survive for 100 days against the swarms of infected. It is a fast and ultra addictive game mode. We plan to release a challenge of the week where all players must play the same random map. The best scores will be published in a leaderboard.Real Time with Pause This is a real-time strategy game, but don’t get too nervous. You can pause the action to take the best strategic and tactical decisions. In Pause Mode, you can place structures to build, give orders to your army, or consult all of the game’s information.
