A strategy on the Dam 00 Agent level. Marc Rützou used this to set the untied world record of 1:54 on 00 Agent and is now standard for any run below 1:59 as it saves more than a full second. It does however make the basement harder to survive as you can't injure one of the guards that often backs you on the way to the mainframe. Some guards will also be lured making the return slightly more chaotic. The strategy works by luring one of the patrolling guards behind the door into the mainframe room. You need to have heavy lookdown throughout the tunnel for this to work. The exact speed the door opens is random, but it will always save time over not doing the lure.

=== 20 Bullet Method ===
This requires picking up at least one KF7, either from the right guard in the very first tunnel near spawn, or from the guard that runs to the alarm after the big gate. In the basement, as soon as you enter the "zig-zag" before the mainframe door section begin firing the KF7 until you've eliminated the guard by the boxes.  This should make enough [[Noise]] that the mainframe area guard is alerted and will open the door for you just as you arrive. <ref>{{cite web | url=

=== 10 Bullet Method ===
It's possible to get the door to open with only 10 bullets, although it's less consistent compared to the 20-bullet method. To do it with only 10 bullets you have to start firing right before you get to the guard by the crates. The door wont be as fast as it would with 20-bullets, but it's a good backup strategy when you don't get 20 bullets.
