Overview
Reactor U92 is a tall, north–south map set in a South Korean reactor complex in meltdown. The west side is taken up by the Reactor Hall, a big curved command room around a boiling containment pool. A road runs down the middle past the Loading Dock, and the east side has the transformer yard with a long pipe walkway along the outer wall. The north end is a yard with offices; the south end is a courtyard.
The map is mostly indoors, so close to medium range is the norm: SMGs for the corridors, assault rifles if you want to cover the road and the transformer yard too. Most rooms have more than one way in, so expect to be challenged from a second door if you sit in one spot for long.
Hardpoint
Five hills, in order: Reactor Hall → Waste Treatment → Loading Dock → Pump Station → Transformers, then back to Reactor Hall.
Pro data from Scout Drop puts most rotations at 8–10 seconds, so sending your first player with about 20 seconds left is standard. The exception is Pump Station to Transformers, a cross-map trip of about 12.5 seconds: leave Pump Station with 25 seconds left. Spawns flip most often on the Loading Dock hill.
Search & Destroy
Attackers spawn in the north yard and defenders in the south courtyard. Bomb site A is inside the Reactor Hall on the west side. B is on the east side by the pipe walkway. In tracked pro rounds, B was planted far more than A (12 plants to 5). The usual CDL route ran down the east side past the Transformers to B, and once the bomb was down, the planting side won most of those rounds.
