Text-based social games have been around for a few years now, with many of them modeled after the successful Facebook game of Mafia Wars. A newer game for iOS named Please Stay Calm, however, is taking that formula and weaving it into a location-based style of play. Combining several familiar gameplay mechanics, it connects users together and tasks them with surviving the frequently used "zombie apocalypse." Developed by Massive Damage, the game offers many good ideas, even if they sometimes feel a bit unrefined.
