Easiest hack n' slash?

Dust

Torchlight 2 would be great although not the easiest.

why not hack, slash, loot?
not eaesy though...
not many achievements though...

Torchlight 1 is faceroll easy

None of these suggestions are hack n slash at all. MGR:R is pretty easy, just parry everything, DmC is also pretty easy, but there aren't many hack n slash games on steam that I know of.

I found Rise of the Argonauts to be easy and enjoyable. If your HP gets low, you just have to dodge for awhile and you'll heal up, so even the hardest difficulty wasn't bad at all.

I cannot attest to the quality of the PC port though, I played the Xbox 360 version and have 100%ed it and I very much enjoyed it. PC version lacks achievements but likely still has the in game challenge of completing the constellations to feed your achievement hunting needs.

try darksouls 2
you can always play it on easy mode :D
but really i would say metal gear rising and prototype, or shank for an old school 2d

Dynasty Warriors franchise?

What's the trick to MGR:R... out of all of them that I have, it was by far the hardest. Couldn't get past the first full mission lol.

If you're looking for a easy game, then why you want to go to the hardest difficulty? Since you said: What is the "easiest" one? Meaning, the easiest to beat on the hardest difficulty. If you want a game to be easy then play on easy difficulty...

Anyways, Dynasty Warriors and Lollipop Chainsaw if you have a console.
