I know Stone Spears have already been suggested, but what about other things? Instead of Arrows only being stone and bone, add metal arrows made from nuggets. Add a bone axe, and metal axes. add spears of stone, bone and metal. shields made of metal. maybe a bone cuirass for ppl who dont have the leather to make armor (and maybe have a Barbarism increase from it). and, of course, the Crossbow! it would have a longer reload and less range than a bow, but do a lot more damage, and maybe use bolts instead of arrows, if you want to get really realistic with them.
and, just a far-out-there suggestion that would be fun, but isn't needed...Siege Engines! Catapults and Balista to help you with those pesky walls, but cost a shit-ton of resources to build, not to mention the ammo! myabe Warships as well, with a small balista mount, and more storage and passengers than the rowboat (which, by the way, why does it fucking fly like their is a motor on it? shouldn't it be slower that it is and kinda fast-slow-fast, cuz of the rowing?
