VALORANT Patch 13.08 introduces a new way to track individual map performance, changes Corrode’s layout and refreshes the Competitive map pool. Released as part of V26 Act 6, this update also adjusts Performance Score calculations, improves the game’s interface and fixes several gameplay bugs. For ranked players, the biggest addition is Map Rating, which measures performance on individual maps using a score from 0 to 500 and a grade from C to S. The patch also brings Bind and Corrode into Competitive and Deathmatch while removing Ascent and Split. These changes affect map strategies, match preparation and how players evaluate their strengths across the rotation.
When Did VALORANT Patch 13.08 Release?
VALORANT Patch 13.08 was released on 13 October 2026 and marks the beginning of V26 Act 6. The update focuses on competitive improvements, map adjustments, interface changes and bug fixes rather than a complete overhaul of the game’s core mechanics.
Its most significant feature is Map Rating, which gives players a clearer picture of their performance on individual maps. Riot Games has also refined Performance Score to better recognise different contributions during a match.
Meanwhile, Corrode receives several layout adjustments intended to improve rotations and make fights around Mid more predictable. These changes could influence how teams approach attacks, defensive holds and retakes.
What Is the New Map Rating System?
How Map Rating Works
Map Rating is a new competitive feature that measures how your proficiency changes on each map over time. Instead of treating your overall ranked performance as the only indicator of skill, it provides a separate rating for individual maps.
The system uses a score ranging from 0 to 500, alongside a letter grade from C to S. Your rating reflects four primary factors: overall win rate, attacker win rate, defender win rate and Performance Score.
Recent matches carry more weight than older matches. Therefore, improving your results on a particular map can help raise your rating as the system evaluates your latest performances.
Where Can You See Your Map Rating?
You can view Map Rating through several areas of the game, including Agent Select, the End of Game screen and Career. These placements make it easier to review your map-specific performance without searching through separate menus.
The feature is available in Competitive and Premier. However, your Map Rating remains private to you, so other players cannot directly inspect your individual map ratings.
Everyone starts fresh when the feature launches. Historical match data does not count towards the initial rating, which means your rating develops through matches played after the system becomes available.
Why Map Rating Matters for Ranked Players
Map Rating can help you identify where your gameplay needs improvement. For example, you might consistently win on one map but struggle to defend another. Looking at your map-specific results can help you recognise that difference.
You can use this information to review agent choices, positioning, utility usage and communication. A lower rating does not automatically mean you are a poor player. It can simply highlight a map where your current approach needs adjustment.
However, avoid judging your ability from a single match. The system considers several performance factors, and recent results contribute more than older games. Consistent improvement is more useful than chasing a higher grade after every round.
VALORANT Patch 13.08 Corrode Map Changes
Corrode receives some of the most important gameplay adjustments in Patch 13.08. Riot has changed defender routes, Mid geometry and the A Site plant zone to address specific problems with rotations and engagements.
These changes aim to make certain fights more predictable while giving attackers better movement options in key areas.
Faster Defender Rotations on A and B Sites
Defenders previously faced longer rotations when moving from spawn towards A Site and B Site. This could make retakes difficult, especially when attackers gained control of a site before defenders could return.
Patch 13.08 adjusts the defender paths leading into the back of both sites. The changes shorten these routes, helping defenders reach contested areas more safely and respond to planted spikes more effectively.
For defenders, the new layout creates opportunities to reconsider retake timings and positioning. Attackers should also pay attention because defenders may be able to regroup more quickly after a site hit.
Mid Changes Improve Attacker Movement
Corrode’s Mid area also receives several adjustments. Previously, attackers often had to move through a narrow choke into Lower Mid, where defenders could use the half wall to spam shots and slow their progress.
The update moves the Mid half wall out by one metre and changes it to metal. This adjustment reduces wall-spam opportunities and gives attackers better options for approaching A Link without being seen from Top Mid.
Riot has also moved boxes at the back of Lower Mid towards B and added a jump-up. The nearby wall has been raised to prevent players from peeking over it from the relocated boxes.
Together, these changes alter the angles and movement routes around Mid. Players should revisit their usual approaches rather than assuming familiar positions will work exactly as before.
A Site Plant Zone Adjustment
The A Site plant zone has also changed. Riot adjusted the area to make playing post-plant from A Link less effective.
This change matters because post-plant positioning can determine whether attackers retain control after planting the spike. Teams may need to reconsider where they hold angles and how they coordinate utility after securing A Site.
For attackers, the best response is to practise alternative post-plant positions. Defenders should learn the updated geometry and identify opportunities to challenge attackers who rely on their previous setups.
VALORANT Patch 13.08 Map Pool Rotation
Patch 13.08 changes the maps available in Competitive and Deathmatch. Bind and Corrode are now in the rotation, while Ascent and Split are out.
This adjustment gives players a different set of maps to practise as Act 6 begins. It also means that strategies built around the removed maps may be less useful for the current Competitive rotation.
Bind returns alongside Corrode, which has received its own layout changes in this patch. Players who already know Corrode should still spend time learning its revised angles, routes and defensive timings.
The rotation also creates an opportunity to refresh agent selections. Some agents may suit particular maps better because of their mobility, information-gathering abilities or site-control utility. However, no agent automatically becomes the best choice simply because the map pool changes.
Performance Score Updates Explained
Riot has also adjusted Performance Score, the system designed to recognise player contributions beyond basic kill totals.
Performance Score was introduced to evaluate the impact of different agents and roles while still recognising strong fragging. After reviewing its early results, Riot identified certain situations where the system placed too much emphasis on additional factors.
Patch 13.08 builds on adjustments that went live during Patch 13.06. The scoring impact of damage, adjusted kills and adjusted deaths has increased. These adjusted metrics include first kills and first deaths.
Chamber has also received specific adjustments intended to reflect his utility usage more accurately.
For players, this means that damage output, combat impact and opening engagements can contribute more meaningfully to the score. Nevertheless, Performance Score should not replace a full review of your gameplay. Good communication, useful utility and smart positioning can still influence whether your team wins rounds.
Interface Improvements and Bug Fixes
Patch 13.08 introduces a new Queue and Mode Select interface for matchmade and custom game types. This update gives players another way to navigate available modes when preparing for a match.
Riot has also added a navigation bar to Career. It makes feature pages such as Rank Legacy, Accolades and Map Rating easier to access.
Several bugs have been fixed across competitive gameplay, audio and weapons. The fixes address an incorrect threshold displayed for the Masterful accolade, certain footstep sounds failing to play in Fog of War, bodyfall audio playing at the wrong location and inconsistent gun-bounce audio.
The update also fixes a Warden scope reticle alignment issue during fully automatic fire. These changes aim to make gameplay feedback more reliable and reduce distractions during matches.
However, not every issue has been resolved. Riot has acknowledged a visual bug affecting Team MVP in Match History, where the result may not display correctly.
The Practice Range in Queue feature has also been temporarily disabled because some players encountered a broken queue state. Riot is testing a fix, but players should check the current client for availability rather than assume the feature has returned.
Riot Shares Act 5 Enforcement Numbers
Patch 13.08 also provides greater transparency about penalties against disruptive players. Riot shared enforcement totals for accounts banned for three days or longer during Act 5’s detection period, which ran from 18 August to 1 October 2026.
The reported figures include more than 171,000 cheaters, 54,000 botters and 76,000 accounts penalised for rank manipulation. Riot also reported 74,000 accounts penalised for toxicity or communication abuse, 288,000 for repeated AFK or gameplay abuse, and 14,000 for using stream-sniping or instalocking tools.
These figures cover different categories of misconduct and reflect Riot’s stated enforcement activity during that period. They do not mean that every reported player received a permanent ban.
Riot has also encouraged players to continue reporting suspicious or abusive behaviour. Reports can help its systems identify patterns and improve detection methods.
How to Prepare for VALORANT Patch 13.08
The best way to adapt to Patch 13.08 is to review the changed maps before entering serious ranked matches. Spend time on Corrode to learn the revised defender routes, Mid angles and A Site plant zone.
You should also use Map Rating as a learning tool rather than a measure of personal worth. Review your results across several matches and look for patterns in your attacking and defending performance.
If Bind is unfamiliar or you have not played it recently, revisit its common site approaches and utility line-ups. Likewise, remember that Ascent and Split are no longer part of the current Competitive and Deathmatch map pool.
Finally, check the game client for any outstanding issues or temporary feature restrictions. Understanding the update before queuing can help you avoid surprises and make better decisions throughout Act 6.
Conclusion
VALORANT Patch 13.08 brings meaningful changes to competitive play through its new Map Rating system, Corrode adjustments and updated map rotation. The introduction of private map-specific ratings gives players a more detailed way to review their strengths, while Performance Score changes aim to recognise combat contributions more accurately.
Corrode’s faster defender routes, revised Mid layout and adjusted A Site plant zone also give teams new strategies to explore. With Bind returning and Ascent and Split leaving the rotation, players should review their map knowledge before jumping into ranked matches.
Overall, Patch 13.08 is an important Act 6 update focused on competitive feedback, map balance and usability. Learning its changes early can help you adapt your tactics and make better use of the new performance information.
