## What "Terraria + DOOM Eternal" means here

2D digging and bosses that pair cleanly with other sandbox titles you own. Slayer speed that people want inside other owned FPS or RPG worlds. Together they are the Terraria + DOOM Eternal mashup slot.

Melty does not need a celebrity mashup name for this query. Terraria + DOOM Eternal is two owned games and one Play button.

Terraria is sandbox action. DOOM Eternal is FPS. Melty starts the mashup on Windows. Uninstall restores files. Multiplayer mashups mint an invite link.

## Play, friends, AI

Press Play. Melty downloads the mashup, installs files, and starts the host. Uninstall puts Terraria / DOOM Eternal files back.

Want a custom Terraria + DOOM Eternal? Paste Melty instructions into Claude Code or Codex — that is the AI masher path on the landing.

## FAQ

### Can Melty mash Terraria and DOOM Eternal?

Yes, if you own Terraria and DOOM Eternal. Melty is an AI game masher / one-click launcher, not a store that gives you the games.

### What does Play do?

It downloads the mashup, installs what it needs, and starts the game. Uninstalling puts every file back as it was.

### Can I play with friends?

Yes, on multiplayer mashups. Press Play to get an invite link, then keep it private, share it, or go public.

### Is Melty safe?

Every upload is checked for dangerous files. If a mashup looks wrong, report it from its page.
