This is an arrangement of "Theme of Tara" from the Metal Gear series, specifically the Metal Gear Solid: VR Missions arrangement, "Sneaking Mode". The last few seconds resemble the timpani drums from Metal Gear Solid 3: Snake Eater's "Snake Eater".
Note 1: Arrangements are listed by order of appearance on the MOJO!!, then YouTube upload. Note 2: Dual Arrangements are sorted by the placement of their rip in the offical playlist, under the character on the left of their thumbnail. This excludes Cool Meme Team, whose duals are both contained under them.
