Mainly particle weapons... first part could be a design decision, but apparently I can't use the ammo for any of them until I've researched all three, and then researched man-portable particle weapons. And even after that I can't construct the ammo.
Reminds me, what ammo is used for the plasma blades? Do they need any?(Research suggests not, but it's an ammo 1 weapon.) I can't find the stats for it. Haven't seen any ammo for it either.
Also like I posted elsewhere, can't find the stats for laser rifle and heavy laser because they use the same ammo as laser pistol, which the ammo seems to show the stats of.
