10 Video Game Secrets You Weren't Supposed To Find
7. Line Mode (Goldeneye 007)
Goldeneye 007 contains many cheat options built into the game, with tweaks like invincibility and infinite ammo being available for players to flick on or off.
But another form of cheating that is also in the game - one that Nintendo and Rare initially didn't tell anyone about - is cheat codes. These codes were only discovered by determined players who spent a lot of time messing around with the game, before being copied onto the internet for future players to use.
One of these codes unlocked something called Line Mode, which turns the entire level into a black-and-white, pencil-on-paper-style drawing. Gameplay-wise the experience remains the same, but it's an awesome-looking mode that provides a bit of extra challenge when navigating the environment and tracking enemy targets.
It's not clear why it had to be hidden behind a cheat code that was hidden inside the game, and why it wasn't included alongside the handful of extra modes that are featured in the standard cheat options list. Maybe the devs just didn't want to share.
