I'm Sorry, Dave
From Halopedia, the Halo wiki
I'm Sorry, Dave is an achievement in Halo: The Master Chief Collection. It is awarded by finding the hidden binary signature, also known as the DAVE Easter egg, in Halo: Reach. The achievement can be unlocked on any level and difficulty.
- The achievement's name is a reference to the quote "I'm sorry Dave, I'm afraid I can't do that.", said by HAL 9000 in the Stanley Kubrick's film 2001: A Space Odyssey.
