You Blew It Up! is a multiplayer achievement in Halo: Reach added with the Noble map pack on Tuesday, November 30, 2010. It is obtained by winning the Phase 2 of an Invasion Game on Breakpoint by playing as Elites.
- The name of this achievement could be a reference to the 1968 film Planet of the Apes in which the main character, George Taylor, yells "You Maniacs! You blew it up! Ah, damn you! God damn you all to hell!"
