Hi Hytaler,
Chapter I added seven goblin gadgets, and most of them change how you get around or how you mine. Here's what each one does according to the official notes, plus the crafting details the hotfixes added. Where the notes don't say something (exact recipes, mostly), I'm leaving it open. Better a gap than made-up numbers.
The seven gadgets
Scrap Drill. A mining tool that breaks a 2×2 patch of blocks at once, and it can also break and loot metal blocks. If you're digging tunnels or clearing space for a build, this is the one you want first.
Scrap Glider. Lets you glide, dive and climb while keeping your momentum. Watch your Stamina though. The official notes literally warn that the landing "gets interesting" if you run out...
