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.

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.
Written for Corrode
No agent row names this map yet. That is a gap in our own research, drawn rather than filled.
