Nuke was revamped last month in a CS:GO update, and the gameplay meta has drastically shifted with the many changes.
The majority of the adjustments to the map seem to be focused on balance for both the Counter-Terrorist and Terrorist sides. This can be seen in the closer, more visible spawns on the outskirts of the map and in the slight changes to both sites, as well as the heavily contested Outside area.
The large crate was rotated slightly, the smaller crates were removed, and old Secret no longer exists. The Outside catwalk, however, is the the biggest change in the update.
To access Heaven, players must now either self-boost from Hell to Heaven via the crates or go up the ladder in the CT hall. Terrorists now also have to strafe jump to the top of Mini from Marshmallow if they want to drop to the ground without taking fall damage.
The changes to the A site were pretty controversial, as the Hut window and upper Catwalk access (ladder) has been removed, along with an obvious revamp of the Roof openings. The box configuration was also reverted to its old iteration to allow for self-boosts onto the Hut.
Executes into the site are now a lot easier from the T spawn roof thanks to the bigger vent openings on the main roof, which allow for quicker lineups. To balance out the easier use of T side utility, the Hut window is now a wall to block a line of sight into Mini and to prevent another T entry point into the site. Now the only choke points into the A site are Heaven, Hut, Mini, Squeaky, and Vent.
Most notably, a new box has been added under Catwalk that allows for faster movement towards Vent. The Secret hallway near the box now has a Z-type formation that gives an extra angle for CTs to fall back onto. A single box and the rails near the Control area were also removed for easier visibility moving into the bomb site.
The chokepoints into the site haven’t really changed much, and only the Secret T route has been made more difficult to advance through. As usual, Ts will have to either fight for Outside, Vent, Secret, or Ramp control to take B site map control.
Update: A recent beta depot has removed the Vent entrance into the site, forcing players to attack the site from either Decon, Window, or Squeaky. The Toxic room was also removed.
