Save warping exploits the fact that many games reload you at a specific checkpoint or save point rather than your exact position when you load a save file. By saving immediately after completing an objective in a remote area, then reloading, runners can teleport back to the last checkpoint or spawn point instead of walking all the way back. This turns what would be minutes of backtracking into seconds of menuing. The technique is so powerful that entire speedrun routes are designed around which objectives to complete in what order based on where the game respawns you after a save reload. Some games even have multiple save warp destinations depending on which checkpoint you last triggered, adding routing depth.
