The Day - Zombie City is a free Android game developed by PREUS. In this game, you have to survive in a world infested with zombies. The game starts with your neighbors turning into zombies, and you, as Tom, have to fight to survive. The game has a similar background to 100DAYS, and your goal is to defeat hordes of incoming zombies and gather gold to upgrade Tom.

The game offers a variety of customization options, including the ability to alter Tom's appearance with various weapons and outfits. As you level up, new skills become available, and you can learn them to overcome increasingly difficult battles. The game saves player data in the device, so deleting the app will terminate all saved data.

Overall, The Day - Zombie City is an engaging action game that will keep you entertained for hours. The game's graphics are impressive, and the gameplay is smooth. However, it would be helpful if the game had an option to save data on the cloud to prevent data loss.
