Methodology
This site lists 571 survivors-like (bullet heaven) games on Steam. The facts come from Steam's public store data, refreshed daily, and the popularity score is calculated from our own daily records of players and reviews.
What counts as a survivors-like?
A survivors-like, also called a bullet heaven, is a run-based game where the player mostly moves while attacks fire automatically, fights growing hordes of enemies, and picks upgrades during the run to become steadily more powerful. Vampire Survivors defined the genre; Brotato, Megabonk and Halls of Torment are well-known examples.
Candidates come from Steam's official "Bullet Heaven" tag, plus games added by hand when the tag misses them. Tags are applied by players and developers, so every game is reviewed before it is listed. Tower defense, idle and incremental games, traditional shoot-'em-ups and plain twin-stick shooters are left out unless horde survival is the core of the game. Adult-only titles are not listed.
Where does the data come from?
| Name, price, release date, developer, platforms | Steam store data, US prices in US dollars |
|---|---|
| Co-op type | The play-mode categories on each game's Steam store page |
| Review count and percent positive | Steam user reviews, all languages |
| Current players | Steam's public player count, sampled every hour |
| Steam Deck status | Valve's Deck compatibility rating |
| 2D or 3D | Steam tags, corrected by hand where wrong |
| Max players and co-op style | Entered by hand; Steam does not publish them |
Hand-entered data always overrides automated data. Images are loaded from Steam and are not copied.
How often is the data refreshed?
Prices, reviews and store details are refreshed once a day. Player counts are sampled every hour. New games under the Bullet Heaven tag are picked up weekly. Each page shows the date its content last changed.
How is the popularity score calculated?
The popularity score runs from 0 to 100 and blends three things for each released game:
| Players (40%) | Average players in game over the last 7 days, on a logarithmic scale that tops out at 50,000 |
|---|---|
| Reviews (35%) | Total Steam reviews, on a logarithmic scale that tops out at 300,000 |
| Rating (25%) | Share of positive reviews, adjusted for confidence (the lower bound of a 95% Wilson interval), so a game with 12 reviews at 100% does not outrank one with 20,000 at 95% |
Logarithmic scales stop the largest games from flattening everyone else: going from 100 to 1,000 players counts as much as going from 1,000 to 10,000.
What are the limits of the popularity score?
The popularity score is not a measure of sales or revenue. Reviews are not sales, and the share of buyers who leave a review varies between games. Player counts favour free games and multiplayer games, and they measure who is playing now, not how many people own the game. Unreleased games have no players or reviews, so they are listed separately by release date and are not ranked.
