To unleash a D Hop in Modern Warfare 3 and Warzone 2, all you need to do is dolphin dive onto an object or a ledge and then press jump. This will catapult you forward with a boost, which makes it tough for your opponents to shoot you effectively. At the same time, it gives you ample opportunity to surprise your adversaries and lay waste to enemies who’re waiting around the corner. It’s a pretty broken mechanic, to be honest.
For those who need a quick refresher course on how to dolphin dive in MW3 and Warzone 2, worry not; all you need to do is press the Circle button on PlayStation or the B button on Xbox while you’re running to unleash a dolphin dive. Your character will then jump forward in the air and land prone.
