Verdict

The call

The clearest difference is in-app purchases: Left Behind Zombie Apocalypse at none against Zombie Outbreak Simulator's 10. Left Behind Zombie Apocalypse also leads on update cadence (every 6 weeks vs every 3 months). Zombie Outbreak Simulator's advantage is rating (4.1 vs 3.7) and ratings volume (1.7K vs 3). On price, ads, device support and iOS requirement there is nothing between them.
