771

771 is an indie first-person horror walking simulator with an approximate playtime of 30 minutes. The player begins in a familiar apartment on an ordinary night. The surroundings then change, with lighting, interiors and walls taking on unusual forms that lead the player further into darkness.

The player leaves their bed and explores a series of unsettling locations, looking for a way out. Strange corridors connect these places, with each passage leading to another new setting. The game is played from a first-person perspective and is built around exploration, with no combat described. Its listed features include realistic graphics and high-quality sound.

The game was made as an experiment by a team of seven developers. Each developer worked on the project for a single day and did not know what the others had created until it was their turn. The result was produced by seven developers over seven days. The game contains flashing lights that may trigger epileptic seizures.
