King Arthur has gone mad from jealousy after finding out about Lancelot and Queen Guinevere's affair. Tricked by his sister, the sorceress Morgana Le Fey, he opens up an hellgate allowing all kinds of demons to enter the world. At the same time, Queen Guinevere has been captured by Morgana and is being held hostage on the magical island of Avalon. When Lancelot returns from his travels he finds the kingdom ravaged by hellspawn. Now he has to face his destiny and go out and cleanse the world from all evil.
Wild Blood is a hack-and-slash action game played from a third-person perspective. Starting out with an enormous sword, Lancelot has to kill all the hellish creatures that crosses his path. A virtual d-pad is used to move around in the world while buttons are used to launch attacks. A single tap leads to a normal attack while holding the button down leads to a heavier attack. To avoid enemy attacks it's possible to dodge and this can be combined with an attack move. After completing the first few levels two more weapons are made available, a bow and twin axes. The player also has access to various skills which act as powerful special attacks. Each weapon has three different skills: fire, ice and lightning.
The player collects coins from killed enemies as well as through crates, barrels and chests that he comes across. Coins can be used to upgrade weapons, skills and player capabilities. They can also be used to purchase health and mana potions. It's also possible to acquire coins through in-app purchases. The player can also collect various crystals that works as power-ups. For example green crystals increases speed while red crystals add extra damage to attacks.
In addition to the single-player campaign there is also multiplayer through local wifi or online. Multiplayer modes include team deathmatch and capture the flag and it supports up to eight players.
