Unreal Tournament's Facing Worlds is easily one of the best multiplayer maps in the history of multiplayer maps—with its towering end-to-end monolith bases, arched thoroughfares, and gorgeous space-faring backdrop. Omri Petitte once described the arena as a "sci-fi uppercut right into your eyeballs", which I think is a pretty wonderful synopsis.
An unnamed Counter-Strike: Global Offensive modder feels the same, it seems, having brought the 17-year old map to Valve's perennial war-torn shooter (with modder Jeisen having cleaned it up and filed it on Steam Workshop).

While I'm unsure if Facing Worlds would work quite as well in Counter-Strike, hearing that theme tune, marvelling at far-off planet Earth, and watching the player scoot around vantage points by way of teleportation really takes me back.
