DHGF: Core3 is where things get interesting and, of course, is why A4Tech charges extra for it. You have the three rapid-fire options of Core2 . The big advantage comes from clicking the N button. Once this is on, your left mouse button will now act as a strafe feature while suppressing recoll and window juddering. You can even adjust the rate of fire from your weapon in-game. If this isn’t enough, the Bloody2 software will let you create macros for your mouse to let you do all sorts of crazy things at the click of a button. You can do some pretty impressive stuff with this mouse – as long as you’re playing First Person Shooters. Otherwise, you’re just paying for an expensive mouse with features you will never use.
