Deus Ex: Human Revolution Cheats
Actually the e-mail was from email@example.com, so you were close. Hackers is one of my favorite movies of all time. (Even tho the hacking in that movie was/is nothing at all like real hacking.)
Dade Murphy, aka Crash Override, aka Zero Cool crashed 1507 computers in one day. As a child (11). Something I'm sure mister "Nucl3arsnake" could not have accomplished on his best day as an adult. Anyways, "Hack the Planet" was the name of the show in the movie run by hackers Razor and Blade.
Awesome movie, anyone who hasn't seen it should... *makes a mental note to see if it's out on Blu-Ray yet*
In another topic, someone mentioned Hangar 18 being a song by Megadeth. There's a steam achievement named Hangar 18 for hacking a computer in a hangar after some scientists escape. After you open the ceiling and they leave, instead of going right as the compass tells you, go left through /those/ doors and move the box to your left. There will be a tiny crawlspace that will let you slip through and you can hack the computer to read a private email. Or, just use the easy access part of the trainer and type in anything for a password. In the email are apparently lyrics for the song Hangar 18 and the log in name is MSTAINE, and it's emails between Dave 1 and Dave 2. The songs lyrics were apparently based on UFO conspiracy theories and it was written by a member of the band named Dave Mustaine.
Here's a video of how to unlock the achievement.
Dave Mustain IS Megadeth ^^
Founder, leadsinger, lead-guitarist and only all-time member of the band.
Another easteregg is very close to the end.
There is a very white room, where you find
and there is an old gramophone. When you use it,
it plays the DX1 main title in an very old,
vinyl-sounding, crackling tone.
Building on that, the entire "Sarif" theme that plays when you're in the SI HQ, most notably when you're walking into his office for the first time, is actually a subtle remaking/remix of the UNATCO theme. Link
And the first door code being 0451 just made me laugh like an idiot.
