How the Hell Do You use the Grapple Hook on PC? :: Star Wars Outlaws Player Support
I'm playing the demo. I'm on the first mission The Heavy, I'm following Hoss, I''ve climbed up above the wrecked speeder and I see a grapple point indicated by a grapple icon that appears, I CAN'T THROW THE GRAPPLE HOOK. E- ENTERACT U- EQUIPMENT C- RELEASE E- SHORTEN LINE Q- EXTEND LINE ?? THROW...
Thanks for your opinion. I do like the atmosphere, yet, I am holding off for now, especially due to the bug I saw in the Demo. Really glad I played the demo. I would have easily run over with my play time during the refund period on Steam, which I think is 2 hrs playtime, and time period of ownership, 1 or 2 weeks.It is a very bland Ubisoft game. The Jedi Survivor games is much more fun, though a really stupid story. If you want an enjoyable Ubisoft game I was pleasantly surprised by Assassins Creed Shadows. Still lacking in many ways compared to the golden years of Assassins Creed games, but the world looks great and the 2 characters you can play are unique and actually fun.
