What "Fallout 4 + Lethal Company" means here
A Bethesda world Melty can combine with other owned RPGs or shooters you already have installed. A hyped co-op loop Melty can join to another owned game you and friends already have. Together they are the Fallout 4 + Lethal Company mashup slot.
Melty does not need a celebrity mashup name for this query. Fallout 4 + Lethal Company is two owned games and one Play button.
Fallout 4 is RPG shooter. Lethal Company is co-op horror. 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 Fallout 4 / Lethal Company files back.

What does Play do?

Can I play with friends?

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