Infestation World is a free-to-play Survival Horror MMO developed by OP Productions LLC. The game was once known as The War Z and takes place in a post-apocalyptic world filled with zombies created by a viral outbreak.

Players take on the roll of one of the last surviving humans, exploring abandoned cities and the countryside while scavenging what they need. As with all zombie-filled universe, the undead may be a problem but it’s the living you have to worry about. While exploring the universe of Infestation World, players will come across other players that may help them out… or may want to kill them and take their stuff. It’s best to be careful.

The game features a Battle mode — which can only be accessed once a player has killed 3,000 and spent 24 hours in the game. This mode features two maps, Rockyford and Fallsdale. In addition to the battle mode, there is also a reputation system in which player actions will determine how they are perceived by others.

To add to the post-apocalyptic feel, players will also have access to different vehicles, each putting off their own “Mad Max” feel. There are also a large variety of items to scavenge in one of three categories, food, water, or medicine. A fourth, separate scavengable resource is weapons. As with everything else, players will be careful when trying to acquire any of these items.
