About

Play Risk of Rain 2 the Megabonk way. You need both games: Risk of Bonk reads Megabonk's characters and art from your own Megabonk install every time it starts, and ships no files from either game.

What you get

20 Megabonk characters as survivors, with their real Megabonk models, next to the Risk of Rain 2 survivors in a Megabonk-style character select.
Megabonk weapons. Each Megabonk character starts with its own weapon on left mouse. Weapons you pick on level-up fill right mouse, Shift and R: four weapons per run. Your Risk of Rain 2 equipment (Q) still works as usual.
Megabonk XP and level-ups. Kills drop XP gems, a Megabonk XP bar fills up, and every level-up offers three cards: tomes or weapons. The game doesn't pause: you're invincible for 10 seconds while you choose.
Megabonk movement. Always at full speed, slide on the Sprint key, bunny-hop, air-strafe and wall-run.
Hordes. More monsters, weaker each, the Megabonk way.
Megabonk boss event at the Teleporter, plus the Ghost King and Shadow King in place of Mithrix and False Son, with a swarm in the final fights.
Megabonk shrines: Charge, Magnet, Moai, Greed, Challenge and Cursed, next to Risk of Rain 2's own shrines and chests.
Bonk style or Rain style. A button in character select: Bonk style builds a random low-poly Megabonk map for every stage, and Rain style keeps Risk of Rain 2's stages with a Megabonk colour grade. Endless like Risk of Rain 2.
Online co-op for up to 4 players, as in Risk of Rain 2. Your difficulty, artifacts and other run options stay.
