Infected: Infect the World

Infected: Infect the World is a tower defense game where citizens of New York has to be protected from an onslaught of violent zombies. The game plays similar to other defense games but instead of towers the player uses police officers and other units to protect the civilians. These are placed on the ground and will begin shooting as soon as the advancing zombies get within their range. Killing zombies earns money which can used to upgrade or buy more troops. Vehicles such as taxis and school buses can also be bought and used to block roads.

The game has a campaign mode which contains a number of missions set in different locations, a survival mode where the player has to stay alive as long as possible and an online mode for multiplayer games. The game uses a free-to-play model where real money can be spent to get more cash to buy stuff such as units and new outfits. Some items are acquired with diamonds which can not be earned through the game but has to be bought.
