10 Video Game Mistakes (That Were Totally Intentional)

10. "Allan, Please Add More Detail!" - Many Hitman Games

In the Hitman: Absolution level "Birdie's Gift," you need to take part in a target shooting mini-game in order to get your precious Silverballer pistols back, and in the event your score ends up being 666, you'll be greeted with the message, "Allan, please add more detail!"

Oops, did IO Interactive accidentally leave a note in the game intended for one of the developers to flesh out some of the flavour-text? Not quite.

This is actually a reference to a mistake from the previous Hitman game, Blood Money, where in the mission "A Dance with the Devil," players who pick up a crate of lobster and read the flavour-text will see "Allan please add details," as one of the dev team seemingly forgot to remove this note to one of the series' 3D artists, Allan Hansen.

Absolution is far from the only game in the series to intentionally reference this gaffe, though - in 2016's Hitman reboot, a post-it note asking Allan to add more details can be found next to a computer, and the HD remaster of Blood Money even hilariously changed the original message to, "Any details yet, Allan?" Brilliant.
