Well there's been some changes since the last beta update, there's a new striker and the scar AR I believe. There's a new shooting challenge and some smaller changes.
Now in terms of gameplay it's as smoother than you would expect, at least for now l know there will be more weapons and much more additions so I guess only time will tell, smooth nonetheless. Barely any bugs if any, the only time I saw a bug or glitch was when I first got into a BR map and the whole screen went gray, other than that found none. Game modes are fast paced and fun as you would expect, the weapons feels somewhat balanced. Visuals/Graphics are pretty good, not overly impressive but decent. Overall it's a great game, although without more game modes and more content I can't say I see it competing Codm, but only time will tell eh.
