Going Commando: Kill ten elite guards with your wrench only
You will need the Taunter: Follow the path until you reach the place past the first lava area, behind you and slightly to the right, you can see a force field and a button to open it behind the force field, and behind that, an alien swarmer. Use the Taunter on it. The alien swarmer will come to you and step on the button that will disable the force field. Jump in the tunnel, and follow the path. The gold bolt is at the end.
You need the Helipack: just before you Swingshot at the two yellow versa-targets, turn around 180 degrees and look slightly to your left. You will see platforms. Jump on them and just follow the path and get the gold bolt.
You need the Swingshot: after the two yellow versa-targets, you will later encounter a green one. Watch out, because there is a large and barely visible lava pit before the place where you have to hook onto the versa-target. Go to the right of the pit and you will see a small, circular metal platform. Jump onto it and then onto the larger platform below that you will then be able to see. Next you will see a grind rail, jump on it, and go to the end of the path. You will have the gold bolt.
