If you are waiting for a key, these are being released in a staggered distribution. Seems a bad way of doing it because there could be people buying on Steam today and getting instant access.
I feel for you,impressions are great so far and as an indication of performance I'm playing in 4K with a 4.8GHz 6700k CPU, 32 GB RAM, GTX1080 GPU with everything maxed out and getting 25-35fps
After a little play. BF fans are gonna hate it. Rambo IS NOT in the house. Squad play and coordination between armor and infantry is really important to success
Yep, traversing the map takes time and it's all pointless taking vehicles/armour unless you have all positions manned. I've only had a quick scout around but need to map my mouse properly will try and put some proper time into it tonight. The foliage is great and provides excellent cover.
