From this position it is possible to swiftly [[speed strafing|speed-strafe]] right and exit the Lucerne Tower completely, free-falling through the level. You need to pick your direction very carefully, and uncrouch right away after you begin to move to get the speed needed to pull off the glitch properly.

A variety of positions lower in the level can be accessed extremely quickly by this method, including the secret "cheese room" (which is not actually ever used for speed runs), Cassandra de Vries' office, the room where the programmer deletes Dr. Carroll's file on [[Perfect Agent]], an external balcony which rings the office floors (a structure which was originally going to be an integral part of the level but was abandoned), the ground floor lobby, an area of pavement outside the Lucerne Tower's front door, and, most importantly, the basement elevator. You can also fall all the way out of the level into oblivion.

For speed runs, the Defection glitch can also be pulled off by landing on the head of a patrolling guard as he walks through the door that you usually use. This is tougher, but consistently faster.

Its original discovery caused a long-lasting storm in Perfect Dark circles  as it enabled the world record for the first level (at the time, 33 seconds) to be lowered to its current [http://www.the-elite.net/PD/stage1.htm 6 seconds], most of which the player spends free-falling ''directly'' into the basement elevator. Modifications of the technique later allowed similar improvements to the SA and PA records.

The Defection glitch has always been a handy promotional tool for [[The Elite]], as it allows the very first level of the game, Defection Agent, to be beaten in a time which the layman would at first sight deem completely impossible (as the elevator ride alone takes longer than 6 seconds). This has the effect of stunning most newcomers who cast a casual glance over the [[Perfect Dark Elite]]'s world records page.
