Old Kingdom Weapons: No offical army however the Pharoah would get volunteers to join and if anything happened they'd fight under Pharaoh, They were equipped with weapons such as Spears, Daggers, Bows and Arrows.
Later on Hyksos invaded and brought Composite Bows and Chariots, however im not entirely sure how you could implement a chariot and another special bow so, maybe not that one
Arrowheads were made with Flint or Copper during Old and Middle Kingdom
The Egyptian soldier would usually carry a simple weapon inventory, a spear with a copper spearhead and a large wooden shield covered by leather hides from an animal, a stone mace was also carried in the archaic period, however it was replaced with the copper battle axe, so those are a few weapons which could be added.
one of the most well known Egyptian weapons which id love to see would be a khopesh, a typical khopesh was usually around between 50-60cm however there is evidence of smaller ones, it was a curved blade used to trap an enemies arm or pull a shield away, the blade was only sharp on the inside, so you shouldnt be able to cut npcs with the outside of it, there was dull ones for ceremonial purposes however Ingame im not sure how a dull sword would be fun.
Basically list of weapons which could be added are
- Khopesh
- Spear
- Shield
- Bow / Composite bow
- Dagger
- Also a slingshot they had.
It would bring more history fans to BS and would widen the player base, if someone was willing to make a map mod + npcs then it could be used for content too, again spreading more information about the mod + game getting both the game more players and the mod more downloads which then gets you recognition, its also just basic weapons so it'd be easy to implement
you could also add stuff which werent weapons but could be used as one
- Crook and Flail
- Ostrich Feather fan
- Staffs
