The eagerly anticipated New Game+ update is now available in Marvel's Spider-Man 2. It adds plenty of additions players have been asking for, and at least one no one had on their bingo card: access to a developer debug menu that messing around in could potentially corrupt your saves and disrupt Trophy progress.
Developer Insomniac addressed the unintended addition on Twitter, warning players that using the menu could get them burned but stressing that playing normally bears no risk. In the interest of not bricking your save game, and as some players have reported opening the menu accidentally, avoid pressing the L3 button while on the save screen.
