Craft

Pick a recipe and the calculator unfolds it to the bottom: every intermediate craft, the raw resources it ends in, the bench each step needs, how long the queue runs and what is left over when a step makes several at once. Set any amount, from one item to a full raid kit. The figure beside each name in the list is the resource that dominates its bill, so you can see what your box can pay for before opening a page.

Most wipes run on a few chains. Gun powder feeds nearly everything that shoots, explosives sit under every serious raid item, and the Level 3 workbench gates the end of both. Price one rocket or an assault rifle once and the night of sulfur farming stops being a surprise.
