Hi, i think the description mentions this briefly. But the factories (portal looking things) drop a random corrupted clockwork piece once destroyed. You can destroy them by shooting them :) Hopefully this helps!
Are those the floating red things?
Hi, yes the enemy factories are floating in the air. They spawn enemies, and drop the clockwork pieces :)
Hi again. I now realize that we weren't clear enough. The abilities are the corrupted clockwork pieces you need to collect :)
