@BERU I've been enjoying Zombie Apocalypse 82-08 and Hiding Out In An Apocalypse(not zombies), but I don't know if these are what you're looking for.
Basic explanation of Zombie Apocalypse 82-08, it basically has 3 stories (might be turning into 4) where there is a military, construction worker and criminal organization where they're trying to survive using the area and materials around them to their advantage.
Basic explanation of Hiding Out In An Apocalypse, MC is a retired first gen hunter against alien-like beings, who builds a bunker, the aliens are characterized into different types, but basically attack, defense, behemoths, commanders, reproduction and infectors which can evolve and change to stimuli.
