Savage Worlds has levels, but not in the D&D sense. There are Novices, Seasoned characters, Veterans, Heroic, and Legendary characters. The ranks reflect a range of experience as opposed to "4th level" etc.
Rather than hit points, SW uses a wound system where you always have the same number of wounds. As you get more powerful, you can become harder to hurt and/or recover easier. But with the exploding dice damage ("Aces"), even a lowly kobold could possibly kill a powerful PC with a lucky dagger thrust.
