Acidnerve and Devolver Digital have announced Titan Souls is coming to PS4 and Vita, as well as PC, in 2015. The game itself is an indie title and seems to take inspiration from Dark Souls at least for the difficulty factor. Players will only have one arrow with with to defeat monsters, and will have to retrieve it if they want to attack again. These monsters will be the Titans, incredibly powerful beasts that can kill players with one hit. When fighting them you’ll have to work out the weaknesses destroy the threat.
Once that weakness is found Titans can be killed in one hit too, making the battles a bit more fairer. The game was first made at a Ludum Dare game jam in December, and since then has been built upon to improve the graphics, increasing the amount of bosses to fight, and making the game world larger. There were also some screenshots released showing a mix of the world, and a couple of the titans that will be fought.
