Shredder is easy.In his first phase he will just shot some energy balls which are pretty easy to deflect.In his second phase,he will summon his clone.His clone is very easy to kill.If clone is summoned Shredder will move only to side where clone is summoned so use it for advantage.His third phase is very easy,just crawl to him and he will fly away,after he shot three beams at you just run to the same position where he land and he will fly again,slash him while he fly away and repeat it untill he die.
P.S.I actually failed to outrun Ch'rell at the end one time,so i defeat Shredder without damage again))) Fortunately he is very easy compare to his first game battle.
