To celebrate Bungie Day (July 7th) 2012, RC Master decided to run through the whole of Reach on Legendary with 11 Skulls on (No Iron or Blind)! Game time is exactly 3 hours 33 minutes!
As he describes in the intro to the video, this is roughly equivalent to the difficulty you are required to play on for the LASO Weekly Challenges. The video comes in at just under 4 hours (including loading and cutscenes) and you can see him doing it live with a little picture-in-picture view of him – which he uses to provide commentary on the run as he does it.
There are a few deaths during the run (8 in all) but only one costs him any real time and most are just unlucky. None of the individual levels are as fast as the single-level LASO speed runs he and others have done – but these are all back-to-back on the day!
The gameplay on the first level, Winter Contingency, starts 6 1/2 minutes in.
If you don’t feel like watching the whole thing in one go, the timestamps for the various levels are in the YouTube description.
Enjoy! And Happy Bungie Day!
EDIT: Bungie actually left a comment on this video using their YouTube account:
You look spry, my man, and focused. Thanks for playing. You make it look easy.
