Prioritize stacking more defenders on B site over A in most rounds, as it often faces heavy rushes and is difficult to retake due to attackers gaining strong post-plant angles after spiking.

With numerous corners on the map, maintain proper crosshair placement when swinging or clearing angles. Shotguns excel here, allowing you to hide in various spots and surprise attackers.

Heavy-penetration weapons like the Odin or Ares, and even medium-penetration ones like the Vandal or Phantom, dominate on B site by shooting through walls and crates. Leverage this for effective spike plants and post-plant plays.

Given the abundance of angles to clear, run double initiators to safely scout corners before site entries—Fade shines with her two prowlers, while Sova follows closely and excels on defense by scanning and wall-banging attackers via darts on entry walls.

Viper and Omen stand out as top controllers: Viper splits sites on attack for smoother pushes, while Omen exploits elevations with teleports and smokes to flank enemies undetected.

Like Ascent, Corrode is a three-lane map where mid control is vital for both attackers and defenders, regardless of rushes succeeding. Attackers securing mid can easily split to the larger A site via its two main entry areas, while defenders should play retakes on A but aggressively contest B to prevent plants.
