Infestation 

Infestation: Survivor Stories (formerly The War Z) is an open world zombie survival horror video game developed by Hammerpoint Interactive.[1][2]Infestation: Survivor Stories features both first person and third person shooting perspectives. The game offers players the option of killing zombies or playing against other users (PvP).[3]

Infestation: Survivor Stories can be purchased and played online without the need for an ongoing monthly subscription with free updates. Players can, however, purchase cosmetic and convenience items such as lessened re-spawn time, additional weapons and ammo, and other items that they would otherwise have to find in the game.[4] Infestation: Survivor Stories has dedicated public servers accessible by all players in addition to player purchased private servers.[5]

The War Z began its closed beta on October 2012,[6] and was fully released on Steam December 17, 2012. Two days after the launch the game was removed from Steam due to false advertising; several features listed in the store description were not available in the game.[7] After rectifying the issue, The War Z was again made available for purchase on Steam on February 26, 2013.[8] The game has since received negative reviews from critics. On June 20, 2013 the game's name was officially changed to Infestation: Survivor Stories.[9]

Infestation: Survivor Stories is a zombie survival game where players endure the hardships of a post-apocalyptic, zombie-infested world. By collaborating with other players, and finding weapons and items, players increase their chances of survival. The game incorporates survival elements like hunger and thirst, which gradually grow over time. Supplies such as food and water can be found to battle the hunger and thirst. If the player fails to properly quench their hunger and thirst, the player's character will eventually die. It is possible to buy food and drinks if the player has none or chooses not to scavenge for the items in the world. Upon character death, players are given the option to either wait 60 minutes before respawning, or pay GC (the game's currency) to revive instantly. Items carried by the deceased character are lost on death - whether purchased in-game or not - but can be found and retrieved by other players, continuing the cycle of life and death in the game.[10]

Safe settlements or safe zones give users an area where they are protected from combat and zombie attacks. There, players can access "Global Inventory" - an inventory shared between characters - and shop for items via the General Store.[5]

Outside the safe zones, players can engage in player versus player combat and player versus environment combat with zombies. Killing other players grants the user reputation based on the victims standing[11] and a chance to collect their dropped items, whereas killing zombies grants the user experience points for use in the game's skill tree.[12]
