# Elements Defender 3D vs Undead Slayer

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.

Both are free to download. Elements Defender 3D sells 10 one-off in-app purchases and Undead Slayer sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for Elements Defender 3D against 4.6 for Undead Slayer. That said, the two scores are not equally well evidenced: Undead Slayer has 471 ratings behind it against 64, so its average is the more settled of the two. Written reviews are what separate them: 93% of Elements Defender 3D's written reviews are positive against 40% of Undead Slayer's.

Elements Defender 3D ships an update monthly, Undead Slayer fortnightly. The most recent releases landed on November 1, 2026 and November 5, 2026 respectively.
