SPTX: It is not a hack and slash, and the reason it's not is certainly not the camera, stop being fallacious.
What defines a hack and slash, first and foremost are the RPG elements, and this game has none. No character creation, no levelling, no character skills, then there is the additional layer that differentiates it from other RPG. Lots of enemies on screen that drop equipment when killed, equipment that has some sort of randomization, usually in the form of modifiers. Without that, it's not a hack and slash.
And NO, you can't say "it's a hack and slash because you hack and slash". That's just plain stupid. In that case StartFox is a First person shooter because there is a cockpit view, Half Life 2 is a puzzle game, Boxing on wii is hack and slash while you're at it and Red Alert is a point and click...
BorderLands is a hack and slash, Devil may cry is a beat them up. You can tie plenty of genres to Rune, action for sure, platformer eventually, even beat them up too some extent, but certainly not hack and slash.
It's not hard to understand.
Oh my god, get over yourself. There is life outside the codex.
