A black-and-white, “car-camo” Razer mouse has quietly appeared on stage at IEM Dallas 2025—and the competitive mouse community is already calling it the Viper V4 Pro.
The prototype shows up during a tech pause in a Team Liquid vs FaZe group-stage match, captured in a close-up of a player’s desk. The mouse has a dense dotted camo print across the shell, white primary buttons and scroll wheel, and a familiar low, ambidextrous Viper-style silhouette. That single broadcast shot, now frozen and zoomed in, is what’s driving most of the speculation.
How the leak spread
The still first started making the rounds in a discussion thread on r/MouseReview titled “Viper V4 pro?”. Users quickly latched onto the camo pattern and overall shape, with some arguing that the side-button placement makes it look more like a compact ergo than a classic Viper, while others insist it’s simply a Viper V3 Pro with a special skin.
Shortly after, mouse YouTuber boardzy pulled the clip into a short round‑up video, “RAZER VIPER V4 AND SUPERLIGHT MINI LEAKED! (shocking)", putting the Dallas sighting side by side with rumors about an upcoming Logitech Superlight Mini. His breakdown doesn’t confirm any specs, but it helped push the leak well beyond hardcore mouse forums.
On X, jakeu+ shared a higher‑resolution frame grab from the same broadcast, explicitly calling it a “Razer Viper V4” leak and noting that some fans believe it might be a smaller “mini” variant of the current Viper V3 Pro. You can see his post here: @jakeufps on X.
What we can actually see
Looking just at the Dallas footage and stills:
- Shell and shape: The top view shows a low, rounded hump with a fairly compact footprint, clearly in the Viper family rather than Razer’s Naga MMO line or the larger DeathAdder. The outline is closest to the Viper V3 Pro but may be a touch shorter and rounder toward the rear.
- Buttons and wheel: The main buttons and scroll wheel are white, contrasting with the black‑and‑white camo shell. Standard two side buttons are visible on the left—nothing obviously experimental like extra paddles or tilt triggers.
- Finish: The “car-camo” wrap matches other unreleased Razer mice spotted with pros earlier this year, notably in another MouseReview thread about Sentinels’ zekken, where commenters compared the pattern to how automakers disguise pre‑production cars.
- Wireless hardware: From the broadcast angle, the dongle itself isn’t visible, so any claims about a new wireless receiver or 8 kHz polling are speculation for now.
In other words, we have a Viper‑like shape in an unusual finish, in the hands of a Razer‑sponsored pro, at a top‑tier event. That’s compelling—but still circumstantial.

Community split: new Viper, camo V3, or something else?
The community reaction so far is anything but unanimous:
- Some MouseReview commenters argue that the side profile clearly looks more ergonomic, speculating it could be an early sample of a Viper‑style ergo mouse or even a DeathAdder variant dressed up like a Viper.
- Others point out how similar it looks to a Viper V3 Pro from the top and suggest it could be a limited‑run camo edition Razer is testing with pros before any retail release.
- A smaller group is all‑in on the “Viper V4 Pro” name, leaning on the timing (following Razer’s recent DeathAdder V4 Pro launch) and the fact that multiple pros across games have now been seen with mice using the same camo wrap.
Right now there’s no clear evidence for a size‑reduced “mini” Viper, nor for substantial shape changes beyond what we can barely infer from the limited camera angles.
Why a Viper V4 Pro wouldn’t be surprising
Even without an official announcement, a new Viper flagship would fit Razer’s recent pattern:
- The Viper line has become Razer’s go‑to shape for competitive FPS, alongside the DeathAdder, and is one of the most used mice in pro play. We’ve already taken a deep look at the current model in our Razer Viper V3 Pro review.
- Razer just refreshed its ergo flagship with the DeathAdder V4 Pro, introducing a new HyperSpeed Gen‑2 wireless solution and updated sensor tech. It would make sense for a future Viper to share similar internals, even if the exact chassis stays close to the V3 Pro.
- Pros at tier‑one events often get early access to unreleased hardware. We’ve been tracking that trend throughout the year in our feature on what mice esports pros are using in 2025.
Seen through that lens, a camo‑wrapped Viper‑shaped mouse in pro play right now feels less like a one‑off and more like part of Razer’s usual pre‑launch testing cycle.
No confirmation from Razer (yet)
Crucially, Razer hasn’t announced a Viper V4 Pro at the time of writing, and the company hasn’t commented publicly on the IEM Dallas footage, the Reddit threads, or the social posts circulating around this prototype.
Until that happens:
- We can’t confirm the final name, specs, weight, pricing, or even whether this exact camo finish will ever be sold at retail.
- It’s still possible—if increasingly unlikely—that this is a Viper V3 Pro special edition or an internal-only colorway rather than a full generational upgrade.
For now, the safest takeaway is that Razer is actively testing at least one new high‑end Viper‑style mouse with esports pros—and the Viper line almost certainly isn’t done evolving.
When (or if) a Viper V4 Pro becomes official, we’ll dig into the shape changes, internals, and performance in detail, and slot it into our mouse reviews and shape hubs alongside the current Viper, DeathAdder, and Naga families. Until then, this Dallas prototype is a fascinating glimpse at what might be coming next for Razer’s most competitive mouse line.
