Wrestling is a confirmed side activity for GTA 6, pointed to by a scene in the game's official trailer footage that shows an arm-wrestling contest playing out in a bar. Arm wrestling has precedent elsewhere in Rockstar's own work. Red Dead Redemption 2 includes an arm-wrestling minigame set inside certain saloons, where you challenge a local and build up power against them for a stake. A bar contest like that also suits the kind of dive-bar setting that Leonida's version of Florida is built around. Rockstar has not confirmed that GTA 6 wrestling works the same way, and nothing has been said about its controls, what you win from it, or whether it counts toward any completion total. Beyond that single trailer scene, the activity is still an open question.
