## What is Overrun?

The dead are coming. Build your base, arm your survivors, and hold the line against wave after wave of the undead. Anywhere, anytime, 100% OFFLINE.

Overrun fuses base-building strategy with fast twin-stick shooter action. Set up turrets and barricades, recruit a team of survivors, then take direct control and blast the horde yourself. Every zombie you drop earns Z-Bucks to upgrade your defenses before the next wave hits.

SURVIVE THE HORDE
Fight off relentless waves of zombies across the suburbs, a hospital, a power plant and beyond. Every map brings new layouts and tougher undead to outsmart.

BUILD YOUR STRONGHOLD
Place and upgrade turrets, barricades and defensive structures. Plan your layout, funnel the horde into a killzone, and turn your base into a fortress.

ARM YOUR SURVIVORS
Equip rocket launchers, .50 cal rifles, grenades, Molotovs and more. Recruit and level up your team to unlock deadlier firepower.

TAKE CONTROL
Don't just watch. Jump in with twin-stick controls and mow down zombies yourself. Call in special strikes, drop first-aid kits and grab power-ups mid-wave.

PICK UP & PLAY
No internet required. Quick to learn with easy controls, and satisfying carnage whether you have five minutes or an hour.

### 1/5 — Purchasing Issues

*2026-06-14, version 2.60*

### 4/5 — W game

*2026-06-13, version 2.60*

w game ngl would love if we can play this also first person,while keeping the original style of the game

### 1/5 — Ads, ads, & more ads

*2026-06-10, version 2.60*

I get it. Developers need ads to help pay the bills. However, the ads in this game are pervasive. After every battle there’s one or two ads. What’s worse, the ads often can’t be closed after they’re done playing. I paid for the ads to be removed. Are they? Nope. It’s either a bug or a grift. The gameplay is mildly entertaining, but the constant ads just ruin the experience.

### 1/5 — No-Ad Purchase Issue

*2026-05-14, version 2.60*

Need to fix the glitch. I purchased the $2.99 no-ad pack and I’m STILL getting ads.

### 4/5 — Good game

*2026-05-12, version 2.60*

Kills the time

### 1/5 — Theft

*2026-05-09, version 2.60*

Purchased “no ads”, nothing changed.  Still get a forced ad after every round.  Money back please.

### 1/5 — In app purchases

*2026-04-22, version 2.60*

Do not appear as purchased
