Unlock the arsenal
Unlocking guns is an advertised progression feature. The public description does not publish a complete weapon list, prices, damage values, or unlock order.
Practical check
Try new unlocks in a comparable run and note what feels different. Do not assume a higher price means a better fit for every class.
