Template:Multiplayer Map Infobox
"Isolation"[1] is a map referenced in the Halo 3 Beta code. No information about it has been provided, and it has not been seen in either leaked or official material. As such, its existence is not confirmed, nor are any of its characteristics. As there are no obvious ties in its name to any previous map. It may be a complete remake of the Halo 2 map Lockout, as opposed to the spiritual successor to Lockout, Guardian (as High Ground is to Zanzibar or Valhalla is to Blood Gulch. There is also a name similarity to Desolation, though it may be completely original. Some fans speculate that Isolation is a remake of Relic, as Relic was on an island, and most islands are isolated from other land,but it can't be remake relic because relic is already remade as Sandtrap,but it is likey it does place on an island
