The Walking Dead: Survival Instinct is a single-player first-person shooter video game developed by Terminal Reality and published by Activision. It is based on The Walking Dead television series, in contrast to the video game by Telltale Games, which is based on the comics. The Walking Dead: Survival Instinct acts as a prequel to the TV series; it is set in the Georgia countryside and focuses on Daryl and Merle Dixon as they make their way to Atlanta during the early days of the zombie apocalypse.
The fact that Activision pushed Terminal Reality to release the game before the release of Season 4 of the TV series ruined it. Terminal Reality set a standard with their other games, Ghostbusters for example but it seems as though Activision was just out to tarnish their reputation. You can tell this game was only in an early creation state and it seems that Activision gave Terminal Reality a month to release it. The controls are buggy and on the PC you can barely see anything. Given at least 6 more months this game would have earn't at least a 7/10. I'm sure that they would have added a lot more levels in and released a lot more new content.
The game has its problems but overall there are far worse out there.
The game features stealth and action, with replayability. By completing the game with certain survivors making it you unlock relics that give you boosts for the next playthrough to better your chances. From silenced weapons to more melee damage.
Sure the game was rushed by Activision because of their greed and laziness. But I say it was worth the buy, just not at the full retail price. :P
