Gameplay in Ninja Gaiden Sigma Plus takes the form of a third person action adventure that sees you controlling your shuriken-wielding death dealer through a variety of different levels. These range from a peaceful Japanese village to a huge airship flying thousands of feet above the ground.
Naturally, being a ninja, Ryu is a dab hand at running up walls, backflipping and dispatching enemies with his trusty Dragon Sword. When battling enemies, combat is based on combining light and heavy attacks to form a devastating flurry of punches, kicks and blows using Ryu's killer weapons.
These include the Dragon Sword, Dragon's Claw and Tiger's Fang twin blades, a nunchaku and a staff. Each weapon can be upgraded by visiting one of the many blacksmiths located throughout the game's vast world, so be sure to spend well-earned experience points on bolstering your favourite weapon's power.
Ryu is also able to learn new attack techniques by searching for scrolls on the bodies of dead ninja, as well as harnessing the forces of the Ninpo - ninja magic used to attack enemies or shield him from damage.
To activate Ninpo, press the Triangle and Circle buttons at the same time, then tap the PS Vita system's rear touch pad to power it up. You can also use the touchscreen to switch to a first person view when firing Ryu's bow and arrow or shuriken, ideal for exacting long-distance attacks against enemies on rooftops or ledges.
