Patch 13.08 brings VALORANT Act 6 and a new personal Map Rating system. Riot also adjusted Corrode, rotated maps, and clarified how recent matches count. Here is what the patch changes and how to use the new information without chasing a made-up meta.
Patch 13.08 starts Act 6 with a new way to read your map form
Riot published VALORANT Patch Notes 13.08 on October 13, 2026, to start V26 Act 6. The headline feature is Map Rating, a personal score that tracks how your performance changes across maps. The patch also adjusts Corrode, changes the Competitive and Deathmatch map pool, updates the queue interface, and lists several audio and weapon fixes. This is a live update, not a preview of a future act.
Map Rating is easy to misunderstand if it is treated as a new public rank. Riot says the rating is private to the player and is available in Competitive and Premier. It evaluates map proficiency on a 0–500 scale with a C-to-S letter grade, using overall win rate, attacker win rate, defender win rate, and Performance Score. Those numbers are meant to help you see where you are improving, not replace the match rank shown to other players.
The notes also say everyone starts fresh when Map Rating launches; historical matches do not count. Recent matches have more weight than older ones once the system is running. That means your first view is a starting point rather than a verdict on your full VALORANT history. Give the system time to collect current matches before you draw a strong conclusion about your best or weakest map.
How the new Map Rating works in practice
Riot lists four main inputs: overall win rate, attacker win rate, defender win rate, and Performance Score. The studio says improving any of those stats can increase your rating, and recent matches contribute more than older ones. This gives players a reason to examine both sides of a map rather than looking only at the final win or loss. If your team struggles on defense but performs well on attack, that split may be visible in the supporting stats.
Map Rating appears in Agent Select, End of Game, and Career, along with map statistics and Top Agents. The information is not visible to other players, according to Riot. That privacy changes how the feature should be used: it can support personal review without becoming another public number to compare in chat. Look for patterns over multiple games, and avoid treating a short losing streak as proof that your rating has settled permanently.
A good review routine is simple. After a match, ask whether the result came from a repeatable issue such as poor rotations, weak utility timing, or losing the same contested area. Then compare that observation with the map breakdown over time. The rating does not explain every round by itself, and the patch notes do not claim it can replace a VOD review or team discussion. It is one more tool for spotting where practice may help.
Corrode changes target rotations and mid control
Riot says it adjusted defender paths toward the back of Corrode’s A and B Sites because rotations were taking too long and making retakes difficult. The goal is to help defenders return to the action more safely. That does not mean defenders can rotate instantly or that every retake is now favorable. The practical change is to learn the updated paths and see how they affect timing in your own matches.
Mid also receives several geometry changes. The half wall is now metal and moved one meter to reduce wall spam and let attackers move toward A Link without being seen from Top Mid. Boxes at the back of Lower Mid moved toward B and a jump-up was added; the wall in Lower Mid was raised to prevent peeking over it from those boxes. These are connected adjustments, so old lineups and sightline assumptions may not behave as they did before.
Riot also adjusted the A Site plant zone to make post-plant play from A Link less effective. Players who rely on a familiar plant and hold should test the updated zone in a custom game before building a strategy around it. The patch page includes before-and-after visuals for several changes. Those official images are more reliable than an old map diagram shared without a patch date.
Map rotation and Performance Score changes
For Competitive and Deathmatch, Bind and Corrode are in the map pool while Ascent and Split are out. That is a direct rotation, not a permanent removal of those maps from VALORANT. If you are queueing with friends, expect the available map selection to reflect the current patch rather than a previous act. Practice time can be redirected toward the maps currently appearing in those queues.
The notes also describe Performance Score adjustments. Riot says it increased the impact of Damage, Adjusted Kills, and Adjusted Deaths, including First Bloods and First Deaths, and made Chamber-specific changes to better reflect utility use. Riot explains that it wanted to reduce edge cases in the measurement. This is not an announcement that raw kills are the only factor or that every agent will receive the same score change.
When reviewing a scoreboard, keep context in mind. A role may create value through utility or space even if its raw damage differs from a duelist’s. Riot’s stated intent is to improve how some contributions are measured while maintaining the value of fragging. The safest response is to play your role clearly and use the updated score as one perspective, rather than altering your entire agent pool around a single rating screen.
The client update and smaller fixes are worth noticing
Patch 13.08 adds a new Queue and Mode Select interface for matchmade and custom game types. Riot also added a navigation bar to Career to make feature pages, including Rank Legacy, Accolades, and Map Rating, easier to reach. These interface changes should reduce menu hunting as more systems are added. If your layout looks different after patching, explore the updated navigation before assuming a page has disappeared.
The listed fixes include Killjoy Alarmbot feedback when a moving doorway destroys the projectile, several footstep and bodyfall audio issues in Fog of War, gun-bounce audio that sometimes failed, and Warden scope reticle alignment during full-auto fire. Riot also lists a Competitive accolade threshold correction. These details may sound small, but clear audio and accurate reticles influence how confidently players read a fight.
Riot also acknowledges known issues: Team MVP could display incorrectly in Match History, and the Range in Queue feature was disabled while the team tested a fix for a bugged queue state. The notes do not state that both issues were resolved in 13.08. If you encounter either, check the current official patch archive for a later status instead of assuming the original note is still current.
How to adjust to Act 6 without overreacting
Start by checking the active map pool and warming up on Bind and Corrode if you play Competitive or Deathmatch. On Corrode, spend a few minutes confirming defender routes, mid cover, and the A plant zone before taking an old execute into a ranked game. You do not need to relearn every map overnight; focus on the specific geometry Riot changed and how it affects your usual approach.
Use Map Rating as a personal review tool. Since everyone starts fresh, give it enough matches to show patterns. Compare attack and defense performance, then pick one concrete habit to work on. Avoid chasing an S grade by taking risky duels or abandoning team utility. The score is a summary signal, while good rounds still come from communication, positioning, timing, and adapting to the opponents in front of you.
Finally, revisit the client interface and known issue list after the update. Riot may publish follow-up notes as Act 6 progresses. If a score or menu appears inconsistent, capture the relevant screen and check whether it matches an acknowledged issue. The patch is most useful when you treat it as a set of specific changes to learn, not a reason to discard every strategy that worked before.
The important Patch 13.08 details at a glance
Patch 13.08 gives players a private map-by-map rating, refreshes Corrode’s paths and cover, rotates Bind and Corrode into the Competitive and Deathmatch queues, and moves Ascent and Split out. Riot also makes changes to Performance Score and updates the client navigation. Those are the details most likely to affect a player’s next few sessions.
The rating starts without historical match data and weighs recent results more heavily. Corrode deserves a short practice visit because its changes affect rotations, mid fights, and a plant zone. The new interface makes the rating easier to find, while the official notes also explain outstanding issues that should not be mistaken for resolved bugs.
If you want to keep up with VALORANT updates, use Riot’s patch page for dates and specific mechanics. Community discussion is useful for seeing how players respond, but it can blur the difference between the developer’s stated change and an early theory about its impact. For now, test the patch, track your own patterns, and let the actual matches shape your read on Act 6.
