RUM VANILLA
Ridiculously Unforgiving Modpack Vanilla VersionR.U.M. Vanilla
The Variation of RUM Remade as a lot of mods broke on the last update! This one has pure challenging spawn rates, and really requires amount of 2 players minimum to play but you can still SOLO for the bigger challenge of beginning levels.
Custom Maps are removed but replaced with a bunch of mods that makes the experience a bit more less crashing.
