This is out on Early Access via Steam for $40. Came out today. Spent about 3 hours playing. Matches are very long, the graphics lookmuchimproved from what I've seen in the past at least. The architecture looks like WH40K stuff should, which is great. But, the game just feels like a huge Conquest map from BF minus everything that makes it fun. The one map I played on has basically one hill that tanks can fight each other on, and that was it. Character animations look solid, as does the 'chunkiness' of bullet impact. I had settings maxed, running two 980Ti's at 3440x1440 and it was still hitching for me, so you may experience some graphical issues/annoyances.
It's still very early in terms of polish, you can tell. Lot of fun if you enjoy WH40k and just want more of the universe but will probably be quite a while until it's polished enough to keep the attention of anyone short of the more hardcore fans. Can't wait to see what the final product looks like though. Every squad I joined was roleplaying, haha. Kind of funny to hear these guys getting so into it.
