A GIFT'S JOURNEY
How a gift reaches the game
Four stops, in under a second.
A viewer sends a gift
From TikTok, Twitch, Kick, YouTube or Starvios: a gift, a follow, likes or a chat command.
OverInteractive
Receives the event, checks your active profile for the matching effect and sends it.
Cuphead mod
A mod the app installs with BepInEx in the game folder that runs every effect inside your game.
Cuphead · levels
The effect hits Cuphead or Mugman mid-fight, instantly.
STEP BY STEP
Getting started
Everything happens from the game's status bar, at the bottom of the app.
- 1
The app finds your game
It detects Cuphead on Steam. If it lives somewhere else, press «Set path» in the bar below and pick the folder.
- 2
Install the mod in one click
Press «Install mod» with the game closed. The app downloads BepInEx, the standard mod loader for Unity games, and drops the OverInteractive mod in its folder. No original file is touched.
- 3
Open Cuphead
Press «Launch game» or open it from Steam as usual. BepInEx loads the mod on its own when the game starts.
- 4
Wait for «Connected»
Once the game finishes starting, the bar below switches to «Connected». Enter a level and from then on every gift reaches the fight.
- 5
Choose what each gift does
In «Profiles» create an example one in a click or build your own: each gift, follow or chat command fires the effect you pick.
EFFECTS
What your chat can do
Each effect is assigned to a gift, a follow, likes or a chat command.
Player 2
The same effects for the second player when two play on the same PC.
Weapons
Ultra weapon, no firing, no switching, no parry, more or less damage, a random weapon or forcing Peashooter, Spread, Chaser, Lobber, Charge or Roundabout.
The boss
Damage or heal the boss, show its health on screen or win the fight outright.
Screen and game
Invulnerable, invisible, inverted controls, slow motion, flipped or spinning screen, zoom, Black & White or Two Strip filters, and coins coming or going.
IMPORTANT
Before you go live
Only inside a level
On the world map or in a menu the effect is not applied. Some don't work in every level either: jumps and dashes not in plane levels, screen spins not in run and gun levels, and weapon effects not in mausoleums.
Player 2 effects
They only work if there is a second player in the game. If you play solo, leave the ones ending in «P2» out of your profile.
Effects that pull you out of a level
«Back to Tutorial» leaves the current level and sends you to the tutorial, and «Kill P1» kills you on the spot. Save them for big gifts.
New mod versions
When a new version is out, the bar below shows it next to the mod and it installs in one click, with the game closed.
FAQ
It adds BepInEx and the OverInteractive mod to the game folder without touching original files.
Yes, in the game's local co-op. There are separate effects for player 1 and player 2; player 2 ones need a second player in the game.
The Black & White and Two Strip filters stay on until another effect changes them. «No Filter» or «Clear Effects» remove them.
Enter a level and wait a few seconds. If it still won't connect, close the game, use «Reinstall mod» from the ⋯ menu in the bar below and open it again.
From the ⋯ menu in the bar below, «Uninstall mod». The OverInteractive mod goes away; BepInEx stays in the game folder without touching original files.
