In this review, Michael discusses how Titan Souls is a game made up of something that would normally only be a side mode or side bit of content, stating - "Boss rush, typically a side game mode, or a bonus stage in video gaming. A mode where you fight wave after wave of the strongest enemies in the game. Typically, this type of gameplay comes at the end of a game, when it has been beaten, a test of the player’s might to see how far they have come since the beginning. Now imagine that the entirety of a single mode is put into that of a video game. That is what we get with Titan Souls, a literal boss rush."
