I have now played through the German SP Campaign and a couple multiplayer matches.
Can't find much stuff that has been changed since the Beta.
There were some bugs related to achievements (unlocked the one for the completion of the campaign after mission 3 and never unlocked any of the training achievements that starts with mission 1).
The Campaign itself was a string of modified countdown matches: You get reinforcements in a set interval, not only after you successfully attacked and objective. The other team also seems to get reinforced in set intervals. Also when you die, you take over one of your teams' bots. So you won't have to sit out until the reinforcement wave.
Each mission was accompanied by a video intro/briefing and extro. IMHO they were well done.
While playing the campaign you are able to toy around with some of the unlockables what was kinda neat.
I was quite impressed with the bot AI. Utilizing cover, hopping over stuff, crawling, ducking - the whole navigation and movement routine.
But there were also some instances where they would get caught up on a fence and couldn't move anymore or where three guys were just running in circles.
But maybe that was just even more awesome AI stuff displaying some kind of shell shock? ... nah, wouldn't want to give them too much credit now, would we?
As Cthulhu mentioned not all of the stats are working as of now. Also, the Deluxe Edition goodies aren't unlocked. A developer stated that they have found the bug and will fix it ASAP. But of course they have to submit the patch to Steam and they have to apply it to their servers. So I figure it will take until tomorrow or even later until the stats (and more important the level up mechanic) are completely up and running.
The MP games I played ran smoothly, I encountered actually no bugs whatsoever.
But because the game just got released most people didn't know how to use their classes. Squad leaders throwing no smoke grenades (only squad leaders and commanders carry smoke grenades - which help a lot when attacking an objective), don't assign objectives; Commanders using no artillery/recon planes; MG Gunners run n' gunning etc.
But that was to be expected. After a couple of weeks this will inevitably improve when the players had the chance to fool around with the classes more.
On the up side, I was able to rack up some respectable kills due to my prior knowledge of the maps, so I had the opportunity to abuse some of the 'kill spots' that were of course widely only known to the beta testers.
All in all I had a fun experience and will surely sink more hours into this game.
