As I have read a number of other people suggesting to remove military weapons and replace them with weapons that would be more suitable for crafting in a post apocalyptic setting, I also think it would be beneficiary to remove the Explosive Charge and replace it with either a battering ram or catapult. These items could be crafted but possibly could have some strict crafting caveats, ie only craftable at your base/multiple people needed to craft/long crafting times etc. Using items such as battering rams or catapults would allow people to enter someones home in a manner that would be more “realistic” in a setting such as this game. However there could be drawbacks to using them, they would have to be carried/pushed to their location, meaning that multiple people are needed to use such items. For instance, 4 people needed to carry/use battering ram, and 4 people need to push catapult however only 2/3 people needed to use it. The battering ram would require multiple hits to open a door/wall and would also require a large surface (enough land or possible 4/6 foundations and can’t be carried up stairs) to correctly operate it. The catapult, however could require maybe 2 hits, but would have to be operated from a distance and the trajectory could be random meaning you don’t get to choose which door/wall is hit.
Anyways those are my suggestions, and i think they would really help to improve the offense and defense portion of the game. No longer would people have to worry about building houses with 1000 doors. We could actually build the houses we really wanted to build.
