Not out of the box — but the MegabonkTogether mod makes it co-op. Megabonk is a co-op roguelike game released in 2025, not enough Steam reviews yet. $9.99 on Steam.
Up to six players survive one run together; enemies, chests, shrines and progression sync. New and moving fast. Steam lists Megabonk as single-player, so it won't show up in Steam's own "games we both own" view as something you can play together — Ready Up counts it anyway, marked "Via mod", and you can hide mod-only games with one filter if that's not your thing.
Smash your way through endless waves of enemies and grow absurdly powerful! Grab loot, level up, unlock characters and upgrade to create unique and crazy…
