If successful, the game will skip the main menu and load you directly into the paused wave you saved. If you see "Invalid Code," you have likely waited longer than 24 hours or used the code once already.

If you're referring to a code related to a game, such as "Among Us" or another game that uses a "Defender" mechanism, or if it's about a specific programming concept or challenge named "Defender 3 Inherit Code," I'll need more context to give a detailed and helpful report.
