Back to the theme ... Another idea that seems interesting to me, would be to use/collect these rescued NPCs as Hired Guns. That is, once "rescued" it would be possible to hire them to fight back zombies alongside us, with a daily cost of money and that could change, given the level of resistance/attack of each different NPC available. As soon as our money runs out to keep them hired, the NPCs would automatically vanish, as if they had defected. By this way we would have a greater need to obtain resources and sell them, in order to guarantee a sufficient amount of money, to sustain our Hired Guns fighting alongside us. This would give 7D2D a new breath and a greater dependency to keep us hooked to the game. These NPCs should also level up, by their killing rate and in result increase their hire price, keep an interesting math rate to the whole idea. Cheers !!!
