Watch a zombie outbreak unfold in real world environments, and alter the outbreak parameters to your liking. Do you prefer old-school slow movers, or the new fast movers? Is the population armed? How well can they shoot? How many police will be on patrol? Customize your own outbreak then watch the chaos unfold. Zoom in and out to keep track of the infection as it spreads across the map! Watch from a high satellite view to get an overview of the infection, or zoom right in and watch as civilians run for their lives, shoot at zombies and inevitably become infected. Keep track of the people's only hope - local law enforcement, as they fight back against overwhelming odds. Join in the action by raining fire from above with Mk81 and Mk82 bombs, delivered by A-10 Tank Killers! Parachute soldiers into the front lines to protect the civilians. Deploy helicopters to rescue civilians before they become overwhelmed. From the Settings screen you can change the following parameters: • Civilian numbers • Civilian armed % • Civilian accuracy • Initial zombie numbers • Zombie outbreak direction (N, E, S, W, Map Wide) • Zombie speed • Infection time (how long it takes for infected civs to turn into zombies) • Number of police • Police accuracy • Soldier accuracy From the Map Select screen you can choose from: • 15 featured online maps, using Google Maps • 5 offline maps (play anywhere even without an Internet connection) • Over 2,500 player maps using Google Maps, created by players of the game at www.class3outbreak.com This free version of the app contains limited features, with in-app purchases for upgrades to unlock the full functionality.

Verdict
The clearest difference is ads: Infection Bio War at none against Zombie Outbreak Simulator's shown. Infection Bio War also leads on rating (4.6 vs 4.1) and update cadence (every 3 weeks vs every 3 months). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Zombie Outbreak Simulator sells 10 one-off in-app purchases and Infection Bio War sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Infection Bio War holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: Infection Bio War has 20K ratings behind it against 1.7K, so its average is the more settled of the two. Written reviews point the same way: 69% of Zombie Outbreak Simulator's written reviews are positive against 83% of Infection Bio War's.
Zombie Outbreak Simulator ships an update every 3 months, Infection Bio War every 3 weeks. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
