10 Hidden Video Game Images You Weren't Supposed To See

10. Da Vinci Code - Twisted Metal 2 (1996)

The trigger-happy demolition derby series, Twisted Metal, absolutely peaked with its second instalment in 1996, turning the destruction, level traversal and overall chaotic fun up to eleven.

And, as seems to be tradition in driving games at this point, the game is chockfull of easter eggs and secrets.

One secret in particular is as intriguing as it is baffling, and I defy you not to have a whack at it yourself for a good while before throwing in the towel.

While driving around, you may come across a low-res version of the Mona Lisa by Leonardo Da Vinci. After admiring its pixelated beauty, you naturally do what you do to everything else in the game: shoot the bejesus out of it.

The painting will catch fire, and as it burns away, a hidden message comes into view behind it. A code of button prompts - Up, Down, L1, R1 - which could mean anything from a cheat code to an unlockable item or level.

In fact, it means none of those things. To this day, no-one has figured out if this code does anything at all.

Will you be the first to crack Twisted Metal 2's own Da Vinci Code?
