The usual way to become a zombie in Innovation Inc. Submarine/Spaceship- style Roblox games is to use the game’s infection or cloning-related mechanic, not a secret code. In one wiki description, the zombie virus is caused by the Cloning Machine failing, or by using the one-time infect button gamepass on the faulty cloning room module.

What to try

  • Look for the cloning room or any infect button in the submarine.
  • If the game has a faulty cloning machine, use it and wait for the infection effect to trigger.
  • In some versions or videos, players also become zombies through special infection events or gamepasses rather than a normal menu action.

If it is not working

  • You may be in a different Innovation Inc. game version, since some guides and videos refer to Spaceship or Arctic Base instead of the submarine map.
  • Some zombie variants, like Master Zombie , have extra conditions such as eating the brain in the Biology lab first.
  • If the server is bugged or the feature is disabled, the infection may not trigger even if you use the right room.

Simple version

  1. Find the cloning or infection room.
  2. Use the faulty clone/infect mechanic.
  3. Wait for the zombie transformation.

TL;DR: In Innovation Inc. games, you usually become a zombie by using the cloning/infect mechanic in the cloning room, not by typing a command.
