Messhof calls it a “2D platforming autoshooter” and a “feverish bullet heaven platformer”. Both phrases are theirs, quoted from the store page — we are not paraphrasing them into something catchier.
What Blood Dungeon is
A Action / Indie game from Messhof, the studio behind Nidhogg. You fight through arenas, collect blood, gold and bones, and spend the bones on permanent upgrades between runs. The soundtrack is dungeon dnb by Thomas Hoey.
What it actually looks like
6 arenas, and how far people get
Steam awards an achievement for clearing each arena’s first boss, named after the arena it unlocks. Lined up, they show the drop-off.
Roughly 21% of players have reached Flood. Everything past that point is beyond what we can verify — we say so on each arena page rather than filling it with invented boss names.

Rare does not mean hard. A late-game achievement sits low on this list partly because most players have not reached it yet — not because it is difficult. These figures are Steam’s global unlock percentages, and they move as more people play.
Someone who isn’t the developer
We have not written a review of our own. We haven’t put enough hours in to have an opinion worth reading, and a made-up score is worse than none.
9 bunkmates, 4 we can name
The store page says nine. Public sources only pin down 4 names, so the other 5 stay unnamed here instead of becoming five empty cards with invented names.

- Steam’s own store API, achievement system and review endpoint. The ones that move carry a read timestamp. The full policy.
Why you can check us
Every number above names its source and, where it moves, the moment it was read. We would rather write “not found” than fill a gap. That includes admitting we have not finished the game.
