Sunken Tombs Returns

A 3D adaptation of Sunken Tombs from the original Risk of Rain! Although it was originally a stage 3 map, this version is a stage 4 map instead. It has a similar layout: tall-ish, mostly underwater with a small above-water layer at the top.

The visuals were specifically based on the map's appearance in Risk of Rain Returns, hence the name, but there's also a few details that aren't really in either version. Hopefully it still feels familiar despite that.

This is not the mod that changes Void Locus to a stage 5 map!! If you're looking for that one, you can find it here.

Monster Cage

Instead of a legendary chest, there's a cage hidden in a random spot in the map. Open it to fight a monster and get a free legendary item, which is dropped next to the cage after it's defeated.

Simulacrum

Sunken Tomb also comes with a Void replication, exclusive to SotV's Simulacrum gamemode. It has a few extra geysers and some vertical lifts (like the ones in Repurposed Crater) to help with getting around. It also has Mini Mushrums instead of Hermit Crabs.

Other Features

  • Uses Sunken Tombs' music from the original game! Specifically, the Returns remasters:
  • Chris Christodoulou - 25 3°N 91 7°E
  • Chris Christodoulou - Hailstorm
  • Category chests and triple shops are more common than on other stages (because the map is so blue that regular chests are sometimes easy to miss..,)

  • Simulacrum Variant: Enabled, Enabled on Stage 1 (true/false)
  • Underwater music muffling (true/false - disabled by default)

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file.

Dependencies

Install these first, or the mod will not work:
