Interesting. I'll have to try this out, I've never played a MOBA before.
Ok, so I gave it a go. First thing I noticed was that my laptop could barely play it. My FPS was awful.
Secondly, it's a top down view of your character, WASD to move. Right click is your primary ability, Q and E are your other two abilities. As far as I can see, that's basically it in terms of gameplay. I only played one game before the shocking frame rate forced me to give up, but it seemed like all you could really do was run around using your small moveset when enemies were near. Maybe I missed out on the subtleties by not continuing to play, but I couldn't see any semblance of tactics. Just run and gun.
Good points? Well, the arena was quite pretty and the Dark Eldar commentator was a nice touch (she reminded me a lot of the announcer from TF2). To be honest though, I'd say wait a few months for more stuff to be added and maybe a little more optimisation to be done.
