Ratchet and Clank: Rift Apart has multiple collectibles, but the most iconic are definitely its golden bolts. Here's how to find all three on
Ratchet and Clank: Rift Apart Scarsu Debris Field Golden Bolt Guide
Getting the first gold bolt here is basically required as part of the main story mission. You'll have to compete in Little Zurkon's Bronze Cup in his arena to advance the story and beat Pierre. After completing all five Bronze Cup challenges, you'll be awarded the planet's first golden bolt.
To get the second bolt, you'll once again have to head to the arena. After the second time you visit the planet for story reasons, KIT and Rivet will both mention that it may be a good idea to hit the arena again before leaving to take on the Emperor. This time, you don't have to complete every challenge in the cup to secure the bolt. Instead, you just have to complete the poison gas challenge. Each cup event has its corresponding reward shown to the right, so you can't miss it. Kill all the bugs Lil Zurkon tried exterminating before the poison gets you instead and you'll have your next bolt.
The final gold bolt is the only one you don't have to compete in one of Little Zurkon's arena challenges for. Instead, return to your ship. From there, walk down the walkway and turn right, then turn right again. You'll end up on a platform with a big stack of crates and explosive boxes at the far end. Destroy these to reveal a mag strip. Follow it around until you're on level ground again, then look up. You should see the bolt ahead. Aim your mag cursor onto the next walkway and press circle to jump over there and grab the bolt. Be careful while you're positioning, as it's easy to accidentally walk off the mag strip.
