Infiltration is a piece of music composed for Resident Evil 4. It appears in the biohazard4 Original Soundtrack as track 1 of the "Aggressive Side" disc. It also appeared in the Biohazard 4 Best Track Collection.
In Resident Evil 4, the track Infiltration is only played twice in Salazar Castle and twice in The island. On Assignment Ada, the track is played once. Infiltration is only played on the game when the player must "infiltrate" a certain area of the game (ex. the cafeteria, The castle parlour, the start of The island, and the waste disposal room. A unique fact is that when the track is played in the cafeteria and the start of the island, at both places, the track is played after Leon encounters Ada.
