Why is a game about being a delivery boy so good? Is it the infrastructure building mechanic? Is it the batshit insane storyline? Is it the fact that every mountain is climbable? Is it the reserved use of combat and massive punishments for killing people?
Who knows, all I can say is I haven't had this much fun with a game in ages.
Ziplines make the ghost areas irrelevant, they're basically just level blocks. You go through once and set up a Zipline over it and never have to do it again unless you want to.
You can also just tool up with grenades and anti-BT guns to kill the thing and the area is ghost free for like an hour so you can set up your Zipline unimpeded. They're super easy to kill once you have the hemetic rounds and the hemetic grenades.
Those areas always exist on the shortest path to force you to take the mountainous/roundabout route until you're high enough level to just take them on. I think the game would be too easy without them.
That's super useful to know. Maybe it's time to finish the game!
