Zombie Rush

Zombie Rush gives different zombie types genuine strengths and weaknesses rather than reskinned health bars, which means a weapon loadout tuned for fast, weak swarmers can struggle badly against a slower, armored zombie type that shrugs off the same rapid-fire approach.

Because upgrades apply broadly across weapons and abilities rather than to one fixed loadout, spreading early upgrade points across mobility and damage tends to handle a wider mix of zombie types than overinvesting in a single high-damage weapon. Reading which zombie type is leading a wave before engaging helps decide whether to stand and fight or reposition to a chokepoint that favors your current gear. Zombie Siege Outbreak covers a similar zombie-survival premise with a heavier base-building and defense layer.
