9 Video Game Secrets That Were Hiding In Plain Sight

3. The Secret Birthday Message - Halo 3

Sometimes in life, you're just not going to be available for a loved one's birthday. In senior engineer Adrien Perez' case though, he was busy putting together Halo 3, so we can mostly forgive him.

Brilliantly, in an attempt to make ends meet, Perez coded a hidden birthday message inside Halo 3's main title screen, though it went unnoticed for seven years. At least, by everyone other than his wife, who it was intended for.

Back in 2014 though, fan Lord Zedd realised that if you set the Xbox 360's internal clock to the 25th of December i.e. Christmas Day, then clicked both analogue sticks in when the game was loading its main menu, you'd get "Happy birthday, Lauren!" displayed inside the Halo ring itself.

D'awww.
