Overrun: Zombie Tower Defense

Overrun is zombie base defense where you also do the shooting. Build barricades, walls and turrets, then take a survivor and fight the waves yourself with twin-stick controls. You pay once and get the whole game: there are no ads, no in-app purchases and no currency packs. There are plenty of zombie games about shooting and plenty of zombie tower defense games about building. In Overrun you build the base, then defend it with a gun in your hand. Each wave makes survival harder than the last. Between waves you spend what your kills earned in the weapon shop, put up new defenses and level up your squad. Weapons, turrets and survivors all unlock by playing, never by paying, and all of it works offline. Barricades and walls are the heart of zombie base defense: they hold the horde back while turrets and traps thin it out. New structures unlock as you push further in, so the base you start with is not the base you finish with. Zombie games often leave survivors in the background. Here they join your squad, level up and carry weapons from an arsenal that grows as you play. When a wave gets close, you take direct control and aim the firepower where it is needed. You face feral runners, hulking demolishers, and radioactive and noxious zombies alongside the ordinary dead. In the middle of a wave you can call in grenades, airstrikes and first aid. Survival depends on the base you plan as much as on your aim. Overrun is a zombie tower defense game that plays fully offline, with no internet needed to play. Leaderboards and achievements are there on Game Center when you want them, and cloud save carries your progress and your purchase across your devices.
