Titan Quest is a game centered on the myths of ancient Greece, in which gods and other creatures are very real and exist alongside people. But they are not going to help humanity and only watch it as if they were their pets, who fight among themselves and only the strongest survive. But it is unknown whether they themselves will cope with the new problem.

The Titans, who ruled the world before the advent of the divine order, were imprisoned in Tartarus for their atrocities, anger and cruelty many millennia ago. A special prison was supposed to contain them for the entire existence of the world, but still they managed to find a loophole and break the restrictions by getting to the surface. They immediately began to wreak utter chaos and destruction around them, breaking down walls, crushing settlements and laughing at the pitiful people. The gods gathered together to consult on how to solve this problem, but the brave warriors did not wait for their help. Armed with swords and other weapons, they went into battle to the death.

In Titan Quest, the player will have to fight powerful monsters on his own, without any magical abilities. Perhaps, over time, the gods will notice him and give him a number of abilities, but for this he must still distinguish himself by his exploits. A wide character class system allows all players to choose the most comfortable playstyle for themselves and go on an adventure.
