Progression (blueprints!), raid balance, base changes, and more.
How do you get scrap? Well, you'll find it in the world, and some items will produce it via recycling.
One other thing: workbenches. Based on the tier of item, it will require a specific level of workbench to craft. You'll be able to find the lower level workbenches at some radtowns, but have fun dragging all your stuff there to craft. The idea here is that each workbench will require a bunch of stuff that can only be crafted at the prior tier of workbench, so you can't really "skip ahead". Workbenches will also decrease how long it takes items to craft: the lower their workbench requirement relative to the workbench you are at, the quicker you can craft them, up to a 75% reduction in time.
There's still some texture and material work needed to improve the skin. Once Taylor has time to take a look and do his thing, I'll be merging everything to main.
If you remember Paul's concept above, Helk decided we wanted an amalgamation of 1 and 4. Pics to come next week. When this is finished, I'll move back onto the nail gun.
