LOS ANGELES--Konami is looking to help out gamers thirsting for a little more action on their consoles. The publisher is showing off two previously unannounced games at this year's E3: Shaman King: Master of Spirits 2 for the Game Boy Advance and Teenage Mutant Ninja Turtles 3: Mutant Nightmare for the PlayStation 2, Xbox, GameCube, and DS.

TMNT 3 brings the mutated reptiles back for some more martial arts beat downs on the evil Shredder and his minions. Based on characters from the comic series, Mutant Nightmare lets up to four gamers play simultaneously as any one of the turtles, whose powers are upgraded as they progress through the game. The console versions will feature the original TMNT arcade game as unlockable content. Look for TMNT 3: Mutant Nightmare this fall.

Shaman King: Master of Spirits 2 is based on the children's morning anime Shaman King. It's the sequel to the action role-playing game released in November. Gamers will once again play as Yoh Asakura, who must be guided on a quest to stop a shaman from calling forth the evil Guardian of Demons. Yoh can capture the spirits of his fallen foes and use them to help in battle. Master of Spirits 2 will be available in August.
