It is well known Night City features pretty neat parkour if you run about grinding on rails or curbs at street-level. However, if you spend the cash on the Cyberpunk 2077 double jump upgrade you can reach new heights. Whilst the double jump leg upgrade will cost you an arm and a leg (excuse the pun) in the region of 40-50K depending on who you see, it is well-worth saving-up for early on. Double jump not only allows you to scale various low fences, but offers alternate means to traverse Night City, to the point where you have way more freedom to explore and climb some of the tall buildings. You might discover some interesting things such is the cool verticality of the game.
