A4tech Bloody Series Multi-Core V7 Gaming Mouse Review

Multi-Core V7 Gaming Mouse

Whenever I’m in the market for a new gaming mouse, there are a few requirements the product has to feature in order for me to even consider making a purchase. This shouldn’t sound too crazy, but I’m looking for comfort, button placement, sensitivity, and drag noise. The A4tech Bloody Series Multi-Core V7 Gaming Mouse looks festive with its bright colors, but how does it measure up to my standards?

Comfort Killed My Button Placement

The mouse fits quite nicely in my hand, though the placement of buttons 4 and 5 feels a bit wonky for my play-style. There’s a comfortable grip for my thumb, which is a nice feature, but I like to have my thumb at-the-ready to press buttons 4 and 5 without hesitation. The V7 has buttons 4 and 5 slightly above the thumb grip, which requires me to move my thumb in order to press the buttons. Unfortunately, this will increase my response time and likely get me killed in the heat of battle.


Determining the ideal sensitivity is different for everyone, and you shouldn’t have any problem adjusting the rate at which your cursor flies across the screen. The mouse is capable of tracking 75 inches a second with a key response time of 1 ms. Not too shabby.

Dragging Noise

While dragging noise on a mouse pad might not be a big deal for some gamers, I find it rather annoying. Of course, if I’m wearing headphones, I’m not able to hear it, but I tend to only wear them when playing with friends over Skype. It’s worth mentioning that I use a SteelSeries HD mouse pad, which consists of a hard plastic composition for consistent precision and remarkable stability. For this review, the V7 was never tested on a cloth mouse pad.

The Multi-Core System

The V7 Gaming Mouse also features a multi-core system that allows for three firing modes with your weapons in first-person shooters. The three vertical buttons located on the top-center of the mouse determine which firing mode your weapon is in. Click button 1 to shoot a single round, button N will swap modes firing two rounds, and finally button 3 switches to a three round burst mode. It’s fairly common to fire in a three round burst to maximize damage with little concern for recoil on your weapon.

Ultra Core 3 software

Here’s where things get interesting, and where the Bloody Series drops the ball. Consumers have to pay an extra $20 for the Ultra Core3 software, giving them an auto-recoil suppression. Keep in mind that this is the same software featured on the product box boasting a “super high headshot rate.”

While it does say on the box you have “the option to upgrade,” I could see the average consumer overlooking it by mistake. The activation code is sent to you via email upon payment. This business model seems a bit silly to me and less than desirable for consumers paying full retail price on a gaming mouse. On the plus side, you get a free trial limited to “1,000 times,” which includes all shots fired. So you better make ’em count!

Games Tested

  • Battlefield 3
  • Borderlands 2
  • Dead Space 3
  • Diablo 3
  • Final Fantasy XIV: A Realm Reborn
  • Left 4 Dead 2
  • PayDay 2
  • Unreal Tournament 3: Black Edition
  • The Walking Dead
  • Medal of Honor

Overall Impressions

I love the idea of three firing modes for my weapons; each mode changes the color of the mouse wheel to either red, green, or yellow to remind you which mode you’re currently in. If the dragging noise, button placement, and $20 additional software fee doesn’t get your goat, then I’d recommend taking the Bloody Series Multi-Core V7 for a spin.

Final Verdict: 7/10

        I wish I could, but we gave ours away to a lucky fan. I’m assuming you’ve reached out to tech support or community forums? Sadly, there’s nothing we can do…
