Cataclysm
Read full descriptionHide full description
Cataclysm is a turn-based artillery game with cats. Pick an angle, pick a power, fire. The ground is destructible — every shot reshapes the battlefield, and the cover you relied on may be gone next turn. • 36-level campaign, yard by yard • Battle the computer, two players on one device, or over the local network • Weapons with their own physics, plus wind that changes every turn • Dress your cat: coats, helmets, bandanas, an eye patch • No ads, no in-app purchases

Verdict
The clearest difference is in-app purchases: Cataclysm at none against Z's 4. Cataclysm also leads on ads (none vs shown). Z's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.0). On price there is nothing between them.
