Lone Survivor: The Director's Cut

The masked protagonist must escape from a city ravaged by disease, by any means necessary. Starving and exhausted, he has begun to question how much of what he sees is even real. How to survive is up to YOU. Sneak through without firing a single shot, or kill everything in your path. Eat and sleep well, or resort to drugs to keep going. Search for survivors, or try to escape the city alone. Look after your mental health, or descend into madness... Lone Survivor is an unusual mix of survival horror, stealth mechanics, adventure games, a virtual pet, a physical and psychological survival simulation and a truly interactive story. The player is encouraged to role-play and forget about the game's inner workings, while the story changes to match the player's actions. This is a game where your choices genuinely matter. The Director's Cut Edition of the game now includes a great deal of new content, graphical and audio enhancements, and the two new endings and side quests also in the recent PlayStation© releases. Contains approximately 35 original pieces of music from UK charting producer Jasper Byrne. A brave and adult story with warmth, humor, and even hope to be found within the darkness. A unique visual style mixing classic and modern techniques with over 125 beatiful hand-painted locations. The Director's Cut also includes two entirely new endings, new Easter eggs, two new side quests, new dialogue for all the characters, and more!
