Unreal Tournament/Awesome

"One asteroid. Two towers. Ten thousand headshots."
 * Any assault map qualifies, but a special mention goes for AS-Overlord, the recreation of the D-Day event of the World War II.
 * CTF-Face, a.k.a. "Facing Worlds". Game Spy mentioned it among the Top-10 Capture the Flag levels for a reason. The map description of the 2004 version describes the arena in one of its many incarnations describes how it works and why it's so popular:


 * [2 HH 16 u EKI 0]&fmt=18 DM-Deck16][]], a remake of the original, with some extra changes.
 * [DM-Morbias[]], another remake of the original one for Unreal I, this time with an extra redeemer.
 * The last match is a 1on1 match against in DM-Hyperblast: a ship going hyperspace. Notably, Xan is a challenge because of the game's (at the time) excellent A.I. (With Dynamic Difficulty for him to boot)
 * DM-Barricade, a castle in the first Tournament... that's floating. In a lightning storm.
 * DM-Phobos: One of the most evocative and disorienting, since the skybox rotates with a panoramic view of Mars.
