The Skedar Jump is a technique used in Perfect Dark on the level Skedar Ruins: Battle Shrine. It involves using a grenade from a Devastator to boost yourself across the gap where ordinarily you would spend several costly seconds activating a nearby bridge. It mainly involves timing, but also (naturally) carries a health risk, particularly on PA.
The Skedar Jump was invented by Ngamer before being improved upon by Discombobulator and eventually GoldenVinze and Jugador.
