One such trick allows players to use the Tactical Sprint (Tac Sprint) unlimited times. Tac Sprint is a mechanic that allows you to sprint at full speed for a short period before returning to a normal sprint. Normally, when you Tac Sprint, you get a short cooldown before you can use it again. However, players have found a workaround to get unlimited Tac Sprint in Modern Warfare 2’s open beta. There are multiple different movement mechanics that you can use during your gunfights that may help you more than you think. One of the movement mechanics is bunny hopping. Bunny hopping is essentially jumping twice to make it difficult for opponents to land shots on you. Players have found a way to use Tac Sprint indefinitely by combining it with the bunny hop. One of the Call of Duty pros and coach Faze Crowder revealed this trick on his Twitter. He shows how the Tac Sprint resets once you bunny hop, allowing players to have “unlimited” Tac Sprints in Call of Duty: Modern Warfare 2.
