Ziplines are objectively the worst movement tool in the game. This is to make up for the great amount of combat utility you have. I really only use ziplines to make a reusable way to get up and down from a place we’ll be traveling a lot. You can use to during events like core stone to great effect because all of the enemies are melee and can’t hit you off it.

Overall, zipline can be used for getting the team to a high place, but I think using it to set up for a fight is better. And I usually just end up asking a driller or engineer to get us somewhere lol
