I did my best to make all the weapons suggested interesting, and bring something different to the table.
These would probably want alternate names in game to match / for legal. I’ve included existing alternate names from HCotW and suggestions for alternate names in itallics.
Hunter (Call of the Wild) Weapon Pack
Marlin Model 1894 (Coachmate Lever) (.44 magnum lever action rifle)
12G double-barrel shotgun (could be called that, or Strecker SxS)
Winchester Model 1901 (Miller Model 1901) (12g lever action shotgun)
This is just a fun tie-in, that allows a classic double-barrel shotgun, a unique type of rifle and a fun alternative shotgun.
These would be the same as the HCotW weapons, just chambered differently - I chose the ones I did in part because they had these other calibers available
German Old War Weapon Pack
Karabiner 98k (Gevär m/39) (7.92×57mm Mauser bolt action rifle)
Mauser C96 (Rugga 1912) (9mm select fire Machine Pistol)
MG 42 (MG3) (7.92×57mm Mauser LMG - could also be chambered in 7.62mm)
The K98k is an iconic, prolific and effective rifle, still in use during the 80’s and 90’s. 8mm Mauser would hit hard enough to hurt the machines, and set it apart as a bolt action battle rifle. Would also want its specific scope added ideally.
The C96 is another prolific item, which also adds a select-fire pistol which is something not in the game.
The MG42 is the granddaddy LMG, which would provide a higher rof, less controllable LMG than the KVM59 and N60
Soviet Old War Weapon Pack
Mosin–Nagant (Solokhin MN1890) (7.62×54mmR Bolt Action Rifle (so 7.62mm))
PPSh-41 (Papasha 41) (7.62×25mm Tokarev SMG - could also be chambered in 9mm)
PTRS-41 (PzB 784) (14.5×114mm Anti-Tank Rifle)
The mosin is the same as the Kar98k in being iconic, prolific and still in use, providing a bolt-action 7.62 rifle, while maybe not the most exciting, it’s a must have.
The PPSh is a classic SMG, and would fill a similar niche to the MG42.
The PTRS is a Soviet competitor to the PVG90, with higher damage and a lower rate of fire.
US Old War Weapon Pack
M1 Garand (M1 Iwaniec) (7.62mm Semi-Auto Rifle)
Thompson M1A1 (Kulsprutepistol m/40) (.45acp SMG)
M2 Flamethrower (Flamethrower) (The bots get it, now so can we! Could probably use Fuel Cells for ammo)
The uniqueness in the US pack is weakest, but they are all very iconic.
The Garand is a given in a classic weapons pack, as a semi-auto Rifle it does overlap with the Kotonek and S21 a little, but neither of those go ping.
The Thompson is the same in many regards. But a high damage, low rof controllable SMG.
And the main ‘difference point’ - the Flamethrower. We already use fire ammo on the machines, and they use flamethrowers on us, so having that as an option would be fantastic.
Old War Weapons Bundle
German + Soviet + US Old War Weapon Packs.
All 3 packs, at a slight discount (~5-10%), I feel like a US weapons mini-bundle would be nice too
