Every figure shows its source. Where a source is missing, the number is a placeholder — and it is never written as fact.

Corrode

Dynamic routes · Decaying walls

The map itself changes route during the round — a memorised default expires.

2 sites · 21 published callouts · outside the pool. Rewards Initiator · Controller.

Both defaults, and the buy

Attacking
Read the wall state before the call, not after.
Defending
Play the route the wall is closing, not the one it opened.
First buy
Buy for the route that still exists — a memorised default expires here.
Utility
Hold utility until the wall state is known; spent early it buys a route nobody uses.

Say it in three

Way in
A Main
Plant zone
A Site
They arrive
A Link

All of A: Crane · Elbow · Link · Lobby · Main · Pocket · Site · Yard. Callout names are Riot’s own; the reduction to three is ours.

1 year old. VALORANT has been patched since, so watch it for how the kit plays, not for numbers — the rest of this page is written for the current patch.

It plays in YouTube’s own player once you press play. Nothing is downloaded or re-hosted here, and nothing loads from YouTube until then.

What the library can do here

The library holds no setup on this map yet — a gap, drawn rather than filled.

A tested starting point

No composition is written for this map — the seven in the Competitive pool have one each, and this is not one of them.

Corrode balance history

    A Site

    • Adjusted wall material on a key surface

    B Site

    • Adjusted wall material on a key surface

    Map Pool Updates

    • BREEZE is IN the COMPETITIVE and DEATHMATCH queues.
    • SUNSET is OUT of the COMPETITIVE and DEATHMATCH queues.
    Why, in Riot's words

    Some of Corrode's wall materials have made certain positions too effective at denying space through penetration alone. We're adjusting the wall materials in key areas so that holding these spots requires more commitment.
