Istanbul Kiyamet Vakti (Istanbul Doomsday) is a free-to-play MMORPG set in a post-apocalyptic Istanbul that was forever changed by a meteor impact. The visual imagery of the game world blends realistic elements with post-apocalyptic, dieselpunk and cyberpunk aesthetics.
The player starts the game as a member of an unnamed special unit and he/she is called a conscript (nefer) and completes the quests given by an organization called Syndicate (Teskilat). The game is a classic MMORPG in terms of gameplay. Players can kill enemies and monsters, complete quests, level up, loot and craft items, and engage in PvP battles with each other.
There are three different classes to choose from during character creation: warrior, mage and healer. Each class has its own skill tree. There are also professions: three for gathering and three for crafting. Gatherers collect resources and crafters create items using recipes.
