Destiny 2’s multiplayer has to balance three different classes each with their own abilities and Super attacks. But since Destiny 2 launched on PC, Titan players have been using an exploit known as “Titan skating” to gain an unfair advantage. It allows Titans to go unnaturally fast, but Bungie is finally addressing it in an update next month.

The Titan’s jump ability is called Lift, and uses momentum to propel Guardians up and forward. If done in a certain way, Titan characters can move far faster than anyone else in the game. While it was possible on consoles in Destiny, it takes finesse to time jumps and gain the full skating effect. But on the PC version of Destiny 2, players are able to create a macro — often by mapping jump to the mouse wheel — which allows them to skate faster and more efficiently than ever.
