Got this months back through their own founders packs, I honestly played for a total of about 6 hours, 1 hour at a time and didn't play it again, I keep track of things on their forums but that's about it.
It's not a bad game or anything, there is just very little content, only Space Marines and Chaos, both of which aren't even fully finished yet, still Eldar and Ork to be added which looking at the pace I've noticed that could be anywhere from a few months to a year lol. So yeah, two unfinished teams, you can choose a few different weapons for each kit right now, but the massive customization isn't anywhere near ready to be implemented from what I've seen. I think they released a new map a while ago, so that makes TWO whole maps to play on now, so yeah, for a third person shooter you can see that it will get really boring for most people pretty quickly.
It does have a lot of potential though, I did have fun playing it and I can see it being a very popular game, at a much later date that is. I would say, keep away for now.
