try
Btooom ( never seen it but i heard it has gore )
Higurashi ( not much gore considering the no. of episodes but when there is, its good. Its psychological thriller so no action )
Deadman Wonderland ( watch the uncensored one )
baccano ( very good action, its set in a modern era so no swords... just guns and fists )
for downloads try bakabt.me, you'll find most of the anime there with varying qualities...
Oh and i have heard Kara no Kyoukai have some pretty good fights maybe @
Arkonov can tell you more about it...
