About
PEAK × GRAIN ROT. You climb PEAK as usual, and GRAIN ROT's treasures lie scattered up the mountain.
What's in it
12 real GRAIN ROT treasures: the Rusty Skull, Hourglass, Clockwork Egg, Voodoo Doll, Old Radio, Telescope, Chessboard and more. They sit beside PEAK's luggage in every biome, in the same spots for the whole team. Their models and textures come from your own copy of GRAIN ROT.
Heavy loot: treasures go into PEAK's own inventory slots and backpack. Each one adds weight to your stamina bar based on its real size in GRAIN ROT, so a greedy haul makes the climb harder. Drop something to lighten the load.
Extract at the Peak: when a scout reaches the summit, everything they carry is banked into one shared team total.
Team haul HUD: what the team has banked, and what everyone is carrying right now.
GRAIN ROT's sound: its loot-grab, drop and cash-register sounds, plus a GRAIN ROT dungeon track in each biome (Forgotten Ruins on the Shore, Frozen Vaults in the Alpine, Brimstone Citadel at the Volcano, the boss theme at the Peak).
Co-op for up to 4: host from PEAK's Play button and invite friends through Steam. Everyone needs Rot Haul.
Good to know
You need PEAK and GRAIN ROT installed. Nothing from GRAIN ROT is included in the download. On the first Play, Rot Haul reads the treasures, sounds and music from your copy in a few seconds and keeps about 200 MB of cache in %LOCALAPPDATA%\RotHaul.
Built on BepInEx for PEAK (Melty installs it). Open source under MIT. Rot Haul's code reads GRAIN ROT with CUE4Parse and vgmstream; credits are in THIRD-PARTY-NOTICES.txt.
