Mobile App Manual Review under COPPA Rule: ‘Zombie Tsunami'

Sep 28, 2023 12:30:00 PM

Welcome to Pixalate’s CTV & Mobile App Manual Reviews According to COPPA, a series containing the detailed factors the Trust & Safety Advisory Board educators used to assess an app’s child-directedness.

The educators manually review thousands of mobile apps available in the Google Play & Apple App Stores as well as connected TV (CTV) apps from the Roku Channel Store and Amazon Fire TV App Store using the COPPA Rule factors shown below & make those results available to the public at ratings.pixalate.com.

This post takes a look at a game which is available from the Google Play & Apple App Stores. Our reviewer discusses how the subjective factors set forth in the COPPA Rule apply to the app and factor into the reviewer's determination as to whether the app is child-directed or general audience (i.e., it is not targeting children).

  • Tabitha’s Take: Zombie Tsunami is a variation of an endless running game where the goal is to eat people to accumulate more zombies for your hoard as you run through the streets of different cities.

COPPA factors used to determine audience

Zombie Tsunami is a game that transforms players into a zombie that must roam the city turning others into zombies. As pedestrians and vehicles full of people are encountered the player has the opportunity to try and grow their zombie hoard. A single zombie can take on a single person, but a larger hoard is needed to take on cars and planes full of people. As the zombie hoard grows they can take on larger groups of people and grow the hoard faster. However, they must be careful to avoid obstacles like bombs and helicopters that can take out zombies!


The cartoon zombies are the biggest reason this game skews more towards children than adults. The zombies in this game are more silly than scary, with oversized heads that often don hats and costumes. There is no blood or gore during the game. As the zombie hoard overtakes individuals and vehicles full of people, there is a poof of pink smoke and the person is transformed into a zombie. That being said the graphics are not overly child-like and are still appealing to teens and adults, earning a mixed audience designation.

The music that plays in the background is upbeat and energetic, more like what you would expect of a game for children than adults. Sound effects are prevalent throughout gameplay, with zombies moaning, explosions, and people shrieking.

During game play, there are mystery boxes that transform the zombie hoard in different ways. For example, the tsunami allows the zombies to surf on a wave that takes out anything in its path. They can also be transformed into an alien zombie that shoots lasers at everything in its path or a football quarterback that crashes through obstacles. 

Diamonds and coins earned during gameplay can be used to upgrade zombies, purchase customization items, and purchase zombie birds that can help out during gameplay.

Video ads are played throughout the game, usually upon dying or completing a level. Optional video ads can also be used to increase incentives or gain extra lives. The advertisements are for a mix of general audiences, mixed audiences, and child-directed apps. 


Rated 9+ in the Apple App Store, Everyone 10+ in the US Google Play Store, and PEGI 7 in the European Google Play Stores. App reviews reflect a mixed audience, with numerous reviews from children and teenagers indicating they are playing the game, alongside some reviews from parents indicating that their children are playing the games. There are also quite a few reviews from adults that indicate they started playing this game when they were children.


The privacy policy, which was last updated on March 31, 2023, is limited and does not address children’s privacy in any way. However, the terms of service, also updated on March 31, 2023, do indicate that users under 13 should not be using the app, and users between 14 and 17 should have parental permission. That being said, there is no age gate in Zombie Tsunami and they do not restrict players under 13 from accessing and playing the game. The privacy policy indicates that the developers collect device information, application information, information that the user gives when contacting the developers, and information collected from third-party services such as IP address, cookies, and browser information. They indicate that they do not share personal information but do share “non-private, aggregated or otherwise non-personal information.”
