Snorms is an isometric third-person shooter. The game takes place over three episodes, two of which are finished (all included in the Desura purchase). It's touted as having an RPG-esque leveling system, which makes it of interest.
I tried the demo out some time ago (long before the game was completed) and I enjoyed it. Time to try it again I think!
From the Desura page:
Snorms features: player leveling, weapon upgrading, 41 maps (3 episodes), 22 enemies, 14 weapons, 10-15 hours of gameplay
