Bionic Commando walkthrough - The Constructor (1/2)
Collectible #1/2: When the level starts, head straight for the large support structure in the middle of the Constructor. Grapple up to the top of it to find the 1st collectible.
Collectible #2/2: The 2nd collectible is down near the bottom of the large hole in the constructor. To get it, take a leap of faith and swan dive off the edge. Angle yourself so you land right on top of the collectible, About 3/4 of the way down, turn around so you are prepared to latch onto the side of the Constructor. As soon as you’ve grabbed the collectible, latch on or you’ll die.
