It will arrive on PSN April 3 in North America and April 4 in Europe.
The survival adventure title from Ubisoft follows everyman Adam Collins in search of his wife and daughter after an unspecified cataclysmic 'event'.
The environment itself has been designed to challenge the player, with thought-provoking choices to be made as part of the story.
The game released earlier this month on Xbox Live Arcade as part of Microsoft's Xbox Live House Party promotion.
Ubisoft has previously suggested that it forsees a "big budget" future for I Am Alive.
Creative director Stan Mettra told Digital Spy last winter: "We're talking about something that is as expensive as Assassin's Creed, or these kind of 'triple A' games, very high production. Teams with several hundreds of people."
