Perfect Arsenal™ Inferno offers something for every type of gamer and every type of game. Perfect Arsenal Inferno includes the vibrant red, high-rise FPS Freek® Inferno, mid-rise FPS Freek CQC™ Signature, and low-rise KontrolFreek Alpha™. FPS Freek Inferno features a comfortable spiral pattern that adapts to the pressure you put on it, so the harder you play, the harder it works to keep your thumbs from slipping. Inferno’s 10.1mm of added height provides a range of motion increase of 135.5%. This gives you the ability to make smaller, more precise in-game movements, affording you the luxury of turning up controller sensitivities to maximum levels so you can turn on your opponents faster and gain the upper-hand. FPS Freek CQC Signature’s proprietary rubber compound and unique concave/convex hybrid thumb surface provides unsurpassed comfort and control. The 6.1mm of height added by Signature creates a nearly seamless feel for those looking for big results but prefer less adjustment time. CQC Signature excels when using subs, shotguns, pistols and when quickness in close quarters is at a premium. Adding a nominal 3.6mm of height, KontrolFreek Alpha’s big performance comes in a small, easy-to-use package. Alpha protects OEM thumbsticks from every day wear and tear and adds extra comfort and grip—thanks to its ultra-wide thumb surface and proprietary rubber coating. Great for any game, Alpha provides a wider thumb surface for better grip while adding minimal height.
