Survivor.io

Zombies have overrun the city in Survivor.io, Habby's adventure game about one fighter with a lot of potential and an enormous horde to hold back. Alongside other survivors, the player takes up arms to fight off the undead and save the city.

The game is built on huge numbers: the developer promises clashes with more than 1,000 monsters on screen at once. Movement is handled with one hand, and the character steers around the map clearing waves while trying not to get cornered, since a single slip against a crowd that size can end the run. Progress within a run comes from a roguelite skill system, where abilities combine in many different ways, so builds change from attempt to attempt. Stages come with their own difficulty levels, raising the pressure as players advance.

It is a big hit, with 50,000,000+ installs and a 4.5 average from 1,121,937 ratings; 79% are five stars and 7% one star. The game is free with ads, and in-app purchases run from $0.49 to $199.99 per item. It was last updated on 2026-09-08, requires Android 8.0 or later, and is rated Everyone 10+. We list 33 versions; the latest, 5.2.0, is a massive 1.9 GB download.

Players who like chaotic horde survival with build experimentation, playable with one thumb, should enjoy it. The 1.9 GB size and the expensive top purchases are the main reasons to hesitate.
