Welcome to the long-awaited sequel to the popular action/strategy game! New weapons, landscapes, and options galore! Every game session is now even more dynamic and amazing. The core of the game is still the same: entire armies of enemies rush at your defenses, trying to destroy them by any means necessary. But now they’re even more powerful and madder than ever. You’ll have access to older, time-tested turrets, as well as completely new types of weapons. It’s up to you to decide how to spend your available budget. Should you build new towers or upgrade and fortify the ones you already have? Turrets vary in terms of their attack range, firing speed, and damage type.

The flexible difficulty settings will allow every player to get as much enjoyment out of the game as possible. If you’re an experienced commander, you’ll love the merciless, intense battles where the countdown where even a fraction of a second is vital to success and everything hinges on your ability to choose and arrange your turrets wisely.

Either way, the thoughtfully designed maps and wide range of available turrets will provide you with virtually endless tactical options. Thanks to the stunning, detailed landscapes, painstakingly drawn towers, and incredible special effect, you won’t be able to take your eyes off the screen.

Every level will challenge you. Are you ready to accept the challenge?

Verdict

The call

Crazy Defense Heroes also leads on rating (4.8 vs 4.6) and ratings volume (8.1K vs 2.5K). Defense Zone 3 HD's advantage is review sentiment (69% vs 54%). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Crazy Defense Heroes holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 2.5K and 8.1K respectively.
