Aquarium is a Team Deathmatch map featuring a room filled with aquariums, and for that reason, players can see through the glass. The Phoenix Time option is also available as a separate map.
- Aquarium (China, Vietnam, Japan & Español, North America).
- Oceanarium (Russia).
- It should be noted that it is a remake of Counter-Strike Online's gallery map, although you can actually see through the middle part of the map.
- Only CrossFire China displays the white shark in middle of the large tank.
