Gameplay is very well done with a bunch of button combination for all obtainable weapons, so there's a weapons for everyone to use. Each weapons is unique on it own. The heavier weapons have slower movement when attacking, while lighter weapons like the dragon sword have quicker movement. Most weapons have three to two levels for you to upgrade. The wooden sword however is the only exception. In order to fully unleash it full power you have to upgrade seven level. When fully upgrade the wooden sword become the unlabored flawlessness the strongest weapon in the entire game making the game a lot easier. Upgrading the levels allow access to stronger and longer combo, which is a must because tougher enemies are present during the later chapters. Dual swords called Dragon's Claw and Tiger's Fang are new addition to Ninja Gaiden Sigma.
If you think it might be too hard for you then just give it a rental, beside there's a ninja dog level for the weak. And even if you played the original and black you should give it a rental, but if you don't like the two from Xbox I recommend you stay away from sigma. If you are up for a challenging, but fun experience then look no further because Ninja Gaiden Sigma is the game for you. If you never play this game yet in your life, then I recommend you tried it out first before laying down your hard earn sixty bucks, and if you do like it then definitely buy it.
