This is a Tool-Assisted Superplay/Speedrun (often abbreviated to "TAS") where a player can edit, rerecord, and manipulate a game into doing whatever that person desires. Visit http://tasvideos.org/ for more information.

With Turbo Mode and not really having to deal with guards, this level becomes pretty much pure strafing and lightning speed. The final time on this is 27.45, but I don't think 0:26 is possible even with really polished movement.
