MEGABONK Multiversum

Play Megabonk as Rambro, Isaac, Leon or Cuphead. MEGABONK Multiversum turns Megabonk into a mashup of the games you own: heroes, weapons, enemies, bosses, items, sounds and maps are read from your own copies of Broforce, The Binding of Isaac: Rebirth, Resident Evil 2 and Cuphead. Nothing from those games is shipped with the mod. Every game fights like itself (RE2 magazines, grabs and headshots, Isaac's tears, Cuphead's parry and super meter), and the Multiverse mode mixes all of them. English and Polish, gamepad supported, single player.

New in 0.29

• Livelier themed maps: about 1.7x the scenery, plus things to break, blow up or pick up in each game's style:
  • Isaac: poop in five kinds, fireplaces, tinted rocks, TNT.
  • Broforce: supply crates, exploding barrels and wrecks, checkpoint flags.
  • Resident Evil 2: herbs, first aid sprays, ammo boxes, typewriters, cars.
  • Cuphead: acorns, crates, jugs, balloons.
  • Their drops are small extras.
• Multiverse game switches: a small panel in the character selection (drag it anywhere) turns single games (Broforce, Isaac, RE2, Cuphead, Megabonk) out of the mix.
• Balanced pace: slightly fewer regular enemies than Megabonk and fewer minibosses in the mod's modes.
• Fixes: invisible enemies; hero tiles no longer show a Megabonk hero's name; a prop dropping gold no longer causes lag; the main menu logo is no longer covered.
• SoulsBonk: shown as work in progress, not playable yet.

New in 0.28

• Boss Rush, rebuilt: boss HP you can see grow over 15 rounds, bosses stay on open ground, a victory party when you win.
• Boss phases every third of their HP, each a clear step up.
• Evened-out weapons, stronger weak extra weapons, a measured boost for small upgrades.
• Fixes: frozen bosses after a level-up, gamepad menus, squashed icons, jump height.

New in 0.27

• Unlocks tabs for Broforce, Isaac, RE2 and Cuphead: every hero, weapon, upgrade and item of your games, with what each one does.
• Mode choice after Play: Megabonk, Megabonk Multiversum or Boss Rush.
• Resident Evil 2 sounds, decoded from your own RE2.

New in 0.26

• Cuphead sounds: shots, parries, supers, every boss's voice and the announcer, read from your own Cuphead.
• Boss Rush economy: steady gold, cheaper chests, more pickups.

New in 0.25

• Bestiary of every enemy and boss you meet, 45 map looks, Cuphead-style boss fights for every boss, and a pause screen that lists what your upgrades do.

New in 0.21

• Boss Rush mode, Cuphead-style three-phase boss fights, the whole Broforce army (42 bros, 30 enemy types, 15 bosses), Isaac expanded, and a new character and mode selection.

Game modes

After Play, choose Megabonk (the original, untouched), Megabonk Multiversum or Boss Rush. Multiversum has tabs at the top of the character selection:

• BROFORCE: 12 bros against Broforce's army; level-ups offer Bro Upgrades.
• ISAAC: 6 of Isaac's family against the basement's monsters; level-ups offer Isaac items.
• RE2: Leon, Claire, Ada and Sherry against zombies, Lickers, Mr. X and G.
• CUPHEAD: Cuphead and Mugman, on foot or in their planes, against Inkwell Isle's enemies and bosses.
• MULTIVERSE: every hero and enemy of every installed game, mixed.

What you need

• Megabonk and Broforce (Steam).
• Optional: The Binding of Isaac: Rebirth, Resident Evil 2 (2019) and Cuphead. Each one's tab appears when that game is installed.
