A new VALORANT Act usually means players ask the same questions.
What changed?
Which maps are in rotation?
What should I practise?
Patch 13.08 gives those questions a slightly different answer.
Act 6 is not built around one giant Agent release or a dramatic weapon overhaul. Instead, Riot has changed several systems that sit underneath everyday matches. Map Rating is new. Performance Score has been adjusted, Corrode has changed, and the active map pool has been reshuffled.
For players who care about ranked performance, those changes are worth understanding before the next queue.
Quick Summary

Act 6 Is Really About Understanding Your Game
The easiest way to look at this update is not as one giant patch.
Think of it as several smaller changes pointing in the same direction.
Riot is giving players more information about how they perform, changing the maps they play, and adjusting some of the systems used to evaluate performance.
That makes Act 6 particularly interesting for players who have reached the point where simply playing more matches is no longer enough.
You need to know why certain matches go well.
And why others fall apart.
Map Rating Gives Every Map Its Own Score
Your VALORANT rank tells you how you’re performing across the competitive ladder.
Map Rating is much more personal.
It asks how well you perform on a specific map.
Every map receives a rating between 0 and 500, along with a grade ranging from C to S.
The system looks at four main areas:
- Overall Win Rate
- Attacker Win Rate
- Defender Win Rate
- Performance Score
That combination makes the system more interesting than simply counting wins.
Imagine you are consistently winning games on one map but struggling badly on another. Your overall rank might not tell you much about that difference.
Map Rating can.
It gives you another piece of information to work with.
Your Recent Games Matter More
Map Rating is not intended to permanently record everything you’ve ever done.
Recent matches carry more weight than older ones.
That’s useful because players change.
Your understanding of a map improves. Your Agent pool changes. A new strategy becomes popular. You might even stop playing a map for months and return with a completely different approach.
A rating that reacts to recent performance makes more sense in that environment.
Everyone Starts From Zero History
There’s also no reason to worry about your old VALORANT career dragging down your first rating.
Map Rating launches with a clean slate.
Previous match history does not contribute to the initial rating.
Your future games build the picture.
And importantly, other players cannot see your Map Rating.
It’s there to help you understand your own performance rather than create another number for teammates to argue about.
Don’t Treat Map Rating Like a Second Rank
This is probably the most important mindset to have.
An S grade isn’t proof that you’ve mastered VALORANT.
A C doesn’t mean you’re a bad player.
The useful part is the difference between your maps.
Maybe you’re excellent on one map and consistently uncomfortable on another.
Maybe your attack-side results are strong but your defense collapses.
Maybe you’re winning rounds but not contributing much in the situations that Performance Score measures.
Those are actionable problems.
The grade itself isn’t.
Use Map Rating as a diagnostic tool, not a trophy.
Performance Score Is Changing Too
Map Rating depends partly on Performance Score, so changes to that system matter.
Patch 13.08 gives more influence to Damage, Adjusted Kills and Adjusted Deaths.
Those adjusted numbers take factors such as First Bloods and First Deaths into account.
That makes the evaluation a little more nuanced than looking at a scoreboard and counting kills.
A first kill that opens a round isn’t quite the same situation as cleaning up an opponent after the round is already under control.
The same idea applies to deaths.
Riot has also made adjustments around Chamber’s utility so that his contribution is represented more appropriately in Performance Score.
For players, the takeaway is simple:
Don’t judge your entire match by the kill column.
Your round impact is broader than that.
Corrode Is Back, But Don’t Play It Like the Old Corrode
Corrode returns to the Competitive and Deathmatch rotation in Act 6.
If you remember the map from its previous run, there’s an important detail to keep in mind.
It has changed.
Riot has adjusted parts of the map after gathering more than a year of gameplay data.
One of the main goals is improving how quickly defenders can move toward the back portions of A and B sites.
That matters because rotation time can completely change a round.
A defender who arrives ten seconds too late might as well have never been on the other side of the map.
Shorter routes can give teams more opportunities to contest a site, support a teammate or attempt a retake.
A Site Deserves Fresh Attention
A Site has also received a change to its plant area.
The adjustment is intended to reduce the effectiveness of post-plant situations played from A Link.
For returning Corrode players, that means old habits are worth questioning.
Don’t assume the plant you relied on before still gives you exactly the same advantage.
Play a few rounds.
Look at the new geometry.
See how defenders approach.
Then rebuild your post-plant habits around what actually happens in your matches.
That is going to be more useful than blindly repeating an old lineup.
The Act 6 Map Rotation
The rotation itself is straightforward.
Maps entering the rotation
- Corrode
- Bind
Maps leaving the rotation
- Ascent
- Split
The change applies to Competitive and Deathmatch.
For competitive players, this should immediately change your practice priorities.
If you’ve spent the last few weeks refining every Ascent setup you know, that knowledge isn’t particularly useful for the current Competitive rotation.
Meanwhile, Corrode needs attention because it is both returning and changing.
Bind is the easier adjustment for returning players because Riot has not made layout changes to it in this patch.
How to Prepare for Corrode
Don’t try to memorise every detail in one session.
Start with movement.
Play enough rounds to understand how the updated defender routes affect rotations.
Then look at the sites.
Where do you naturally take fights?
Which areas feel difficult to retake?
How quickly can your team regroup?
Only after that should you start worrying about more specialised setups.
A map becomes easier when you understand why you’re moving somewhere.
Not because you memorised a line on a minimap.
Ascent and Split Are Out — So Change Your Practice
Players often keep practising what they are comfortable with.
That’s understandable.
It’s also inefficient when the map isn’t currently in your queue.
With Ascent and Split leaving Competitive and Deathmatch, your warm-up time is better spent on the maps you’re actually going to encounter.
That doesn’t mean forgetting those maps completely.
It means adjusting your priorities.
The VALORANT map pool will change again eventually. Players who can quickly rebuild their understanding of a new rotation will always have an advantage over players who rely entirely on familiar setups.
Vanguard and Competitive Integrity
Patch 13.08 also comes with another reminder that competitive VALORANT isn’t only about gameplay changes.
Riot has published enforcement figures covering Act 5.
During the reported period, Riot says it banned more than:
- 171,000 accounts for cheating
- 54,000 for botting
- 76,000 for rank manipulation
- 74,000 for toxicity or communication abuse
- 288,000 for repeated AFK or gameplay abuse
- 14,000 for stream-sniping or instalocking tools
These figures don’t change how you play a round.
They do show the scale of the systems operating around competitive VALORANT.
If something looks suspicious, reporting it still matters. Riot says player reports help improve its detection and enforcement tools.
The Smaller Changes You Might Notice
Patch 13.08 isn’t only about Map Rating and Corrode.
Several bugs have also been addressed.
Among the fixes are issues involving:
- Masterful accolade requirements
- Alternate footstep audio
- Bodyfall audio in Fog of War
- Gun bounce sounds
- Warden’s scope reticle alignment
The Practice Range has also been temporarily disabled following a queue-related issue.
One problem remains known as well: Team MVP can display incorrectly in Match History.
So if your post-match screen looks strange, that particular issue may not be your imagination.
What Competitive Players Should Do Now
You don’t need to completely rebuild your VALORANT routine because Act 6 arrived.
A few changes are enough.
Start by learning the rotation
Know that Corrode and Bind are in.
Ascent and Split are out.
That alone prevents wasted preparation.
Give Corrode a few relaxed games
Don’t make your first goal an impressive rating.
Learn the map.
Pay attention to rotations and retakes.
Check your Map Rating later
Once you’ve played enough matches, compare your maps.
Don’t ask, “Is my grade good?”
Ask, “Why is this map so different from my others?”
Look at both sides
A map can expose a specific weakness.
If your attack win rate is healthy but your defense isn’t, the answer probably isn’t another aim-training session.
You may need to rethink positioning, rotations or utility usage.
Think beyond kills
Performance Score now places more emphasis on damage and adjusted combat results.
A player who consistently creates valuable openings can have a different impact from someone collecting late-round kills.
That’s worth remembering when reviewing your own matches.
A Simple Act 6 Routine
If you’re coming back after a break, keep it simple.
First: learn the current rotation.
Then: spend a few games getting comfortable with Corrode.
Next: look at your map-specific results.
After that: identify whether your problem is attack, defense, combat performance or map knowledge.
Finally: practise the weakness you actually found.
That’s much more useful than jumping between ten different guides and changing your playstyle after every loss.
Final Thoughts
Act 6 doesn’t completely reinvent VALORANT.
It does something more subtle.
It gives players more information about their own performance while changing the environment in which that performance happens.
Corrode returns with adjustments.
Bind comes back into the rotation.
Ascent and Split step out.
Performance Score changes how certain contributions are weighted.
And Map Rating gives players a new way to look at individual maps.
That last addition could become the most useful one.
Your rank tells you how you’re doing overall.
Your Map Rating can help answer a different question:
Where are you actually strongest?
And when you find the map where you’re consistently struggling, don’t treat that rating as a failure.
Treat it as a lead.
Because knowing where you are weak is often the first step toward becoming better.
