I absolutely loved it, that's why I kept going back to play it over and over again. I don't think it suits voice chat though.
It's very different to other shooters like COD in that it's way way more chaotic, just none stop blast em up, that's why I don't think there will be any need to discuss tactics during the match. There's too much going on for that kind of thing, you need to fully concentrate on watching the landscape and obv shooting ink. I couldn't imagine speaking to people whilst playing, and even if I could I wouldn't have much to say. There's just no need IMO, it's too fast paced.
