The latest update for Marvel's Spider-Man 2 promised a lot of long-awaited features, but I don't think anybody, including the developers at Insomniac, expected it to include a full debug menu loaded with goofy, game-breaking features and some apparent details about the game's DLC plans.
It looks like all you need to do to open the dev menu is hit L3 and R3 on the save select screen, or press the touchpad and options button at the same time during gameplay. Players are still figuring out the limits of what the menu can do, but it appears that this is the tool Insomniac would've used to test the game - meaning you can do things like give yourself infinite health, skip through missions, or spawn into otherwise inaccessible test rooms.
