Get Unlimited Power Nodes
In chapter 14, juast after the Zero-G area there is currently a glitch which allows you to get an unlimited amount of power nodes, just follow these simple steps or watch the video below to see how.
Save your game, exit it and reload it. Now, make your way back to the secured storage room earlier and you'll find replenished power nodes. (If you see credits only, just restart the checkpoint and try again.) Now head back to save your game again and reload the saved file and do it again. Sometimes you'll get one or two power nodes. If you're lucky, you'll find two nodes and a Ruby Semi-conductor.
