Doomsday

The game starts with the shelter. You build and expand it, and that base is what you defend from zombie hordes and hostile factions. Early play also involves recruiting heroes and training troops, since each troop type has a different combat role.

The Z-Virus Adventure upgrade adds expeditions. You assemble a team from scratch, head into the wasteland, scavenge resources and arm yourself against the clock.

The map uses a spherical terrain system with zoom controls, so you can move from a close view of your shelter out to a satellite view. The wasteland is covered in fog and you explore it step by step.

Players can join alliances and fight alongside others worldwide, or raid other shelters to sustain their own. Google Play shows the game has no ads, which matters in a genre that often leans on them. It does have in-app purchases, so spending is optional but present.

The game was released on September 14, 2021, and the latest update is from October 23, 2026.

Doomsday asks for planning and ongoing involvement with other players. If you want a similar survival-strategy game, Last War:Survival Game is the closest name in the alternatives list. For a lighter, more casual take on zombies, Plants vs. Zombies is the better pointer.

For quick action instead of base management, Zombie Catchers, Dead Target and Earn to Die 2 are listed as other options. The Teen rating also rules it out for younger children.

Doomsday: Last Survivors is made by IGG.COM (igg.com) and rated Teen. It shows no ads, but in-app purchases are part of the game, so keep an eye on spending if younger players join in. Because alliances put you in contact with players worldwide, check the Data safety section on the store page to see what information the game collects.
