Whenever a new game is started or a save file is loaded, the RNG seed will always be reset to the same value. Depending on the room Soma loads into, it is sometimes possible for the player to perform standardized movements and actions to advance the RNG deterministically to , until it reaches a value which produces a desired drop from a specific enemy.
