Lone Survivor

Lone Survivor is a 2012 independent survival horror video game, developed by Jasper Byrne under Superflat Games.

It is a post-apocalyptic survival horror game with retro-styled 2D graphics. Players control an isolated, surgical mask-wearing survivor of an infection which has turned the world's population into aggressive, shambling mutants. With limited food and an increasingly fragile mental state caused by his isolation, the player character must be guided outside his apartment in order to look for other survivors. There are no indications that any others survived the apocalypse, bar a note which encourages the player to locate a party of survivors on the other side of the apartment building.
