How do I start?

Start by researching Bolt-action Rifles tech. You can get the ingredients to make gunpowder and primers from stone.

Why are the guns so strong/weak?

The weapon damage is balanced around vanilla and Bob's enemies. Let me know if they feel over- or under-powered with certain other mods. I'll put up code to dynamically adjust their damage when said mod is active.

How does trading work?

Make gun boxes, sell them for cash, and exchange cash for resources/science. All is done with assembling machines (for now.)
