Infectonator 3: Apocalypse

You play as the force behind a zombie outbreak, aiming to spread infection across the globe before humanity can develop a cure. A campaign map connects locations where you launch outbreaks and work toward goals that let you advance through the world.

Each level is a small battlefield where you choose where to release the virus and deploy zombies, traps, and other tools. Use the environment, including doors and walls, to help the infection reach survivors while human defenses fight back.

Between outbreaks, you spend resources on upgrades and use DNA to unlock and craft zombie mutations with different abilities. New locations, escalating countermeasures, random events, and optional modifiers shape the campaign and its replay runs.

Players who enjoy the game often like its straightforward outbreak strategy, the fun of building up a zombie force, and its pixel-art style, comic references, and nostalgic feel. Some also find it an engaging game to play in short bursts. Reviews frequently criticize the later campaign for becoming repetitive or grindy, and opinions differ on its difficulty, which some find spiky and others find too easy.
