Many "multi20" repacks advertised as "online multiplayer" actually only support split-screen via a virtual controller. True online play requires port forwarding on your router (Port 3074 or 27015), which exposes your PC to external attacks. Furthermore, because you aren't using Steam servers, there is no anti-cheat. A single player with a "crash gun" mod can corrupt your entire save file.
For the technically curious, here is what happens when you run the setup.exe for legoworldsmulti20repack.
Step 1: Unpacking
The repack uses FreeArc or Zstandard algorithms to decompress the .bin files. Because LEGO Worlds uses repetitive texture files (bricks, studs, minifig parts), the compression ratio is exceptionally high—often 60-70%.
Step 2: Crack Application
The installer automatically copies modified .dll files (specifically steam_api64.dll) into the game root. This fools the game into thinking Steam is running. For the "multi20" variant, it also installs a SmartSteamEmu.ini configured for LAN mode.
Step 3: Registry Tweaks
Many repacks include a registry fix to disable the "Checking for updates" prompt that attempts to re-download the official launcher.
Step 4: Multiplayer Bridge
The "multi" aspect is actually handled by a wrapper. When you select "Multiplayer" in the repacked game, it launches a virtual server that bypasses Steam's matchmaking. Players must enter the host's IP address manually.
Note: You must disable your antivirus during installation. The crack uses "generic injection" techniques that modern antivirus software (Windows Defender, Malwarebytes) flags as "PUA" (Potentially Unwanted Application), even though it is technically a false positive.
Before you risk your PC’s security, consider the legitimate path to the "multi20" experience.

How to get the "Multi20" features legally:
The Steam Remote Play Together loophole: If you want "multi" but only you own the game, use Steam's Remote Play. It streams the game to a friend, and they control a second character. It works perfectly for LEGO Worlds co-op.
This specific filename represents the pinnacle of convenience for the end-user. It represents a "Definitive Edition" of sorts—not officially, but functionally.
