Verdict

The call

Elements Defender 3D and Undead Slayer both sit at 4.5 stars, but that hides the real split: 93% of Elements Defender 3D's written reviews are positive against 40% of Undead Slayer's. Elements Defender 3D also leads on ads (none vs shown) and iOS requirement (6.0 vs 16.0). Undead Slayer's advantage is ratings volume (471 vs 64) and update cadence (fortnightly vs monthly). On price, rating, in-app purchases and monetization model there is nothing between them.
