How To Find the Hidden Binary Signature in Halo: Reach

The release of Halo: Reach for The Master Chief Collection brings back all of the classic fun from Bungie’s fan-favorite shooter, including its original Achievements. One of those achievements is called “I’m Sorry Dave,” and it requires players to find the hidden binary signature in Halo: Reach. Where is this hidden binary signature hiding out? As it turns out, the answer is right under your nose.

To find the hidden binary signature in Halo: Reach, equip a non-scoped weapon, then zoom in using the right stick button (RS). A string of binary code will appear in the lower left-hand side of the screen. Keep that code on-screen for a few moments and the “I’m Sorry Dave” Achievement will unlock.

Easy, right? Still, some players might be wondering what the code is supposed to mean. As it turns out, the string reads “01000100011000010111011001100101,” which is binary for “Dave.” This is a reference to Dave Candland, the former Microsoft and Bungie developer who worked on the user interface in past Halo and Destiny games. Candland has since moved on from Bungie to Monolith Productions, but the “I’m Sorry Dave” achievement still remains in-game to honor his legacy in the Halo franchise.

It’s rather appropriate that in order to find the hidden binary signature in Halo: Reach, players have to pay special attention to the user interface itself. The Halo series has an instantly recognizable style, and much of that style is owed to Dave Candland’s fine work on the series’ user interface. Perhaps “I’m Sorry Dave” is a bit of tongue-in-cheek humor on the part of the development team—or perhaps it’s just a clever sci-fi tie-in to 2001: A Space Odyssey—but either way, it’s a fun little achievement that honors one of the game’s designers.
