Sengoku 2, the sequel to Sengoku, casts you as two street fighting heroes caught in the midst of a supernatural attack by the undead forces of the evil Nobunaga from the Japanese sengoku period. The game warps you through several time periods and locations to fight evil, from feudal Japan to WWII Europe.
The gameplay is a standard 2D side-scrolling beat 'em up, where you have to proceed through each stage by killing all enemies that cross your path and defeating the stage boss to proceed. New features include swords as default weapons, which now feature both high and low attacks, as well as a block move that allows you to parry enemy attacks.
Collecting orbs gives you weapon upgrades and energy attacks, as well as the ability to morph into any of the three spirits released in the original game. These new forms grant you a new arsenal of moves and powers, adding depth to the gameplay.
