Zombie Survival 2

Zombie Survival 2 puts more emphasis on exploring than most games in this category. A dangerous world occupied by zombies is laid out across abandoned cities, dark alleys and creepy forests, and the game frames each level as a new adventure rather than another arena — so getting through is about moving through somewhere rather than holding a position. Various weapons are collected as you go, and traps can be set to defend yourself against the massive waves, which means preparation is a real tactic alongside shooting. Big zombie bosses arrive to test whether the preparation held, and there are useful items scattered through the environments for players who look for them.
