VALORANT patch 13.08 begins V26 Act 6 with a new private Map Rating for Competitive and Premier, a revised Corrode, a changed Competitive and Deathmatch map rotation, published Act 5 enforcement totals, and several audio, accolade and visual fixes. Map Rating starts everyone with fresh data and does not replace rank or appear to other players.

What patch 13.08 changes

Riot Games released VALORANT patch 13.08 on October 13, 2026, as the opening update for V26 Act 6. The most visible addition is Map Rating, a per-map performance measure shown as a number from 0 to 500 alongside a grade from C to S. The patch also reworks parts of Corrode, changes the map pool in Competitive and Deathmatch, publishes account-ban totals from Act 5, adjusts Performance Score calculations, and fixes several audio and interface problems.

Map Rating explained

Map Rating is designed to show how a player’s proficiency on an individual map changes over time. It is not an opponent-facing rank: Riot says other players cannot see the information, and the patch notes do not say that it changes matchmaking or Competitive rank.

How the score is calculated

Four inputs contribute to the rating:

  • Overall win rate
  • Attacker-side win rate
  • Defender-side win rate
  • Performance Score

Recent matches count more heavily than older matches. Improving any of those four measures can raise the rating, so the system is not limited to kills or match wins alone. Riot has not published a formula showing the exact percentage assigned to each input.

Fresh tracking and supported queues

Historical match results are excluded at launch. Every player therefore starts Map Rating with fresh tracking when the feature goes live. The feature is available in Competitive and Premier.

You can view the rating and related statistics in Agent Select, on the End of Game screen, and in Career. Riot also says the interface can show features such as Top Agents for a map. The official patch notes describe the feature as: “Map Rating: Time to see if your favorite map is your best map.”

  • This code is only redeemable on Riot Accounts in North America and Canada

Performance Score adjustments

Riot says Performance Score was built to recognize contributions from different agents and roles while still rewarding fragging. At launch, Riot reported that Performance Score and ACS identified the same Match MVP about 70% of the time. That is Riot’s own reported comparison, not an independently audited study.

Riot later identified cases in which the additional factors were weighted too strongly. Adjustments made during patch 13.06 increased the influence of Damage, Adjusted Kills and Adjusted Deaths. Those adjusted measures include First Bloods and First Deaths. Riot also made Chamber-specific changes intended to represent the value of that agent’s utility more accurately.

Competitive and Deathmatch map rotation

Patch 13.08 changes the named map queues as follows:

Queue Maps added Maps removed
Competitive Bind, Corrode Ascent, Split
Deathmatch Bind, Corrode Ascent, Split

This rotation statement applies to Competitive and Deathmatch. It does not establish a change to every other VALORANT queue.

What changed on Corrode

Riot says the Corrode update follows more than a year of observing matches and collecting data. The goals were to speed up defender rotations and make mid control less of a prolonged brawl.

Shorter defender routes

Paths from defender spawn toward the backs of both A and B sites were changed to shorten rotations. The intended result is faster retake access after attackers take a site.

Mid adjustments

  • The mid half wall was changed to metal and moved one meter. Riot says this should reduce wall spam and open a route toward A Link without exposing players to Top Mid.
  • Boxes at the back of Lower Mid were moved toward B and given a jump-up.
  • The nearby wall was raised so players cannot peek over it from those relocated boxes.

A Site post-plant change

The A Site plant zone was adjusted to make post-plant play from A Link less effective. Riot’s notes frame this as a balance change to the strength of that specific post-plant position, rather than a broad redesign of the site.

Riot’s Act 5 enforcement totals

Riot has begun publishing enforcement figures more regularly. The following numbers cover accounts fully banned from VALORANT for at least three days during the Act 5 detection period from August 18 through October 1, 2026. They are Riot-reported account totals, not a count of unique people, and they do not specify the sanction for an individual case.

Category Accounts banned
Cheating 171,000+
Botting 54,000+
Rank manipulation 76,000+
Toxicity or communications abuse 74,000+
Repeated AFK or gameplay abuse 288,000+
Streamsniping and/or instalocking tools 14,000+

Riot’s rank-manipulation category includes boosters, boostees, hitchhikers, wintraders and other related cases. The figures should not be read as a complete description of VALORANT’s penalty ladder.

Bug fixes in 13.08

  • Corrected the threshold displayed for the Masterful accolade.
  • Fixed alternate footsteps that sometimes failed to play in Fog of War.
  • Fixed bodyfall audio events occurring at the wrong location when an agent died in Fog of War.
  • Fixed gun-bounce audio events that did not trigger as expected.
  • Fixed Warden’s scope reticle becoming misaligned during full-auto fire.

Known issues after the update

Riot lists two issues separately from the fixes. Team MVP can display incorrectly in Match History. Riot also disabled Practice Range in Queue while testing a fix for a problem that placed some players into a broken queue state. These are outstanding issues, not features removed from the game permanently.

What players should expect when they log in

  1. Check the Map Rating panels in Agent Select, End of Game and Career; the system begins with fresh tracking rather than importing old match history.
  2. Expect Bind and Corrode in Competitive and Deathmatch, with Ascent and Split removed from those two queues.
  3. Review Corrode’s mid cover, defender routes and A Site plant area before relying on older lineups or retake paths.
  4. Remember that your Map Rating is private. Other players cannot inspect it, and Riot has not stated that it changes rank or matchmaking.
  5. If Match History shows an incorrect Team MVP or Practice Range in Queue behaves unexpectedly, treat it as a listed known issue rather than a local settings problem.
