Map layout

Corrode has two sites, A to the north and B to the south, and three lanes linked by a long mid. Attackers come in from the right of the map: A Lobby leads to A Main then to A Yard, B Lobby leads to B Main then to B Site. Mid is played from Mid Bottom toward Mid Stairs, Mid Top and Mid Window, then A Link or B Link open onto the sites. A is the bigger site, with A Yard, A Elbow, A Pocket and A Crane, and several high positions. B is more compact and favors the defense: narrow passages and B Tower as a high angle. The map plays on several levels, catwalks, towers and floors, and its stone can be shot through. In patch 13.08, Riot shortened the defenders' paths to the back of both sites to speed up rotations.

Key features

Three lanes and a long mid

Mid links the two sites with a long corridor: it is the map's control point, with Mid Top, Mid Window, Mid Stairs and Mid Bottom, and it leads to A Link and B Link. In 13.08, the mid half-wall became metal and moved about a meter, so that you can reach A Link without being seen from Mid Top.

Several levels and see-through stone

The map stacks catwalks, towers and floors, and its stone can be shot through. Angles often come from above or below: raise your crosshair and check heights before every duel.

A plant zone adjusted in 13.08

Riot changed the A plant zone so that the post-plant from A Link is less effective. A guide from before 13.08 may therefore describe a plant or post-plant that no longer holds.

Shortened defender paths

The paths from the defender spawn to the back of A and B were reworked in 13.08 because rotations were too long. Site retakes arrive faster than before.

Site A

A is the map's big site: an open A Yard, A Elbow and A Pocket on the north side, A Crane toward the defender spawn. It has two entries, A Main on the attack side and A Link on the mid side, and high angles for defenders. The plant zone was changed in 13.08.

Attack plan

Enter through A Main toward A Yard. The dodge.gg guide cites Initiators like Breach and Sova for the map: throw some info (Sova's Recon Bolt, Breach's Fault Line) before entering as a group, then plant in the A zone. Since 13.08, the plant zone is adjusted against the post-plant from A Link: don't count on it anymore, and check your post-plant in game.

  3. 3Plant : Plant in the A zone

Defense plan

Put Sentinel gear on the A Main entrance: Cypher's Trapwire and Cyber Cage with a camera at the top of the entrance, or Vyse's Razorvine, Shear and Arc Rose (Sportskeeda setups from 2025). Also hold a high position on A Yard. The defender paths to the back of the site changed in 13.08: check your rotations and your retake in game.

  3. 3Info : Spycam on the entrance

Site B

B is more compact: one main entrance through B Main, narrow passages and B Tower as a high angle. It is easier to defend than to take, and B Link connects it to mid. The defender paths to the back of the site changed in 13.08.

Attack plan

Enter through B Main with an Initiator: the March 2026 dodge.gg guide considers Breach nearly essential for B executes, because he clears the narrow passages. Plant in the B zone then hold the B Main entrance. Keep something to delay the defuse. Access through B Link is not described: mid and the B back paths changed in 13.08.

Defense plan

B is compact and favors the defense. Put Cypher's Trapwire on the B Main entrance and, with Vyse, Razorvine, the Shear along the wall and the Arc Rose across from it. Hold a high position from B Tower, with a Cypher camera on the green structure of the site. These positions predate 13.08: check them in game.

Vyse

Vyse A: Razorvine and Shear on the A Main entrance crate

Defense · Site A

Place the Razorvine on the wooden crate near A Main, line up the Shear on the same crate to block the way, and stick the Arc Rose to the wall across from the entrance to blind. The source's second Razorvine, on the site's other entrance, is dropped: that area changed in 13.08. The positions predate 13.08.

  3. 3Arc Rose : Arc Rose on the wall across from the entrance to blind

Vyse B: Razorvine at the entrance, Shear along the wall, Arc Rose across

Defense · Site B

Place Razorvine at the B Main entrance, run the Shear along the entrance wall and put the Arc Rose across from it. The source's first Razorvine, in the middle of the wall toward B Link, is dropped: access from mid changed in 13.08. The positions predate 13.08.

  1. 1Razorvine : Razorvine at the B Main entrance
  2. 2Shear : Shear along the entrance wall, to block access to the site

Corrode tips

  1. Corrode has several levels (catwalks, towers, floors) and stone you can shoot through: check heights before you peek, A Yard and B Tower first.
  2. On B, play with an Initiator who clears the narrow passages: the March 2026 dodge.gg guide considers Breach nearly essential for B executes.
  3. On A, don't count on the post-plant from A Link anymore: the plant zone was adjusted in 13.08 against that placement.
  4. The flooded passages make noise when you run through them: walk to mask your arrival and listen for the opponents'.
  5. Keep something to delay the defuse after the plant: retakes are faster since the defender paths were shortened.
