I am Dean "Rocket" Hall, Creator of DayZ and submitter of Mount Everest, AMA!
I'm Dean Hall, known as Rocket, and I created the "DayZ" mod for ArmA2, which I then developed as a standalone game and just sold over a million units in the month since release.
I also climbed Mount Everest in May last year.
This is a well known account for me on reddit (see r/DayZ), but here is my proof on twitter: https://twitter.com/rocket2guns/status/425989418948648960
Ask me anything!
Edit: Dammit. I spelt the title wrong, that should say "I summitted Mount Everest" not that weird typo/grammar thing I did.
Edit 2: Last few questions now guys, we're getting ready to finalize the current build so I'll need to focus on that.
AMA FINISHED: Thanks guys! It's been a blast! Sorry I couldn't answer more questions, got really hard to read them. Hope some good info came out.
