I had zero interest in Arc, I watched a brief video a year or so ago and not much else.
I grabbed the playtest for the server slam last weekend and I have to say that I'm pretty excited for the release. It looks amazing, it runs super smoothly and they've gone a long way towards polishing and updating the game systems so it is fun to play and dying doesn't feel as punishing or unfair. (though, those flying rocket UAVs are the spawn of satan)
