Verdict

The call

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.
