There are more ways to get around the island. The game is adding a grappling hook in the first patch. A grappling hook makes things better.
The main description is here.
To begin swinging, shoot its grappling hook at a hard surface like a cliff, prop, or building. Each successive swing gets faster until the third swing and beyond, when you’ll be at max speed. If you miss a shot and land on the ground, you’ll have a brief window of time to shoot the grappling hook and come back swinging. You’ll have an even longer window if you slide out of a swing, so don’t be afraid to combo some slides into your swinging action. But don’t worry if the window of time runs out: after a brief cooldown, the grapple glove will ready itself back up.
It resembles the Spider-Man swinging that was introduced in chapter 3. Vehicles like cars and trucks, and faster movement through sprinting, climbing, and sliding are just some of the mobility options in the game. The options have become more important as the game has become more similar to other games.
The game started in June after a large-scale battle.
