Adding new weapon types that require new graphics to the game at this point is extremely costly, so that won't be happening I'm afraid.
That said, I too would like to see shotguns and I'm sorry now that I haven't included them from the start. So if I ever decide to add another weapon type, like through an expansion, DLC or some such, it will almost certainly be shotguns.
Dual wielding would entail even more cost in graphics and a bunch of coding in many aspects of the game, so that won't be happening.
I would love to see a DLC where you can craft shotguns like one from metro 2033 and last light. Shotguns or the most sample ballistic weapon you can ever make in life.
Also i would like to see you adding in pipe bombs too. If you do make this DLC i would buy it in a heart beat.
Also i would like to ask you what you base this game off. Because it feel like a fallout game but done way better in the name of controls and the trading system is a lot better too in how you make people what they want.
Also i would like a carfting system where you do traler and earro.
Btw i got your game on steam
