Hello! Thanks for the review! However there are some ways to prevent the horde invasion. The easiest one is to start strengthening you base from the very beginning by crafting different kind of protection. The more challenging one is to kill the witch that lives in the Infected forest, so that nobody could summon zombies. Good luck!
Hello! Thanks for the review! You can start playing with real survivors only in Crater which is a quite dangerous location as behind it there's an aggressive biological environment. Therefore you need to be an experienced survivor (100+ lvl) to prepare for it very thoroughly! Good luck in the game;)
