Yes, apparently there was an armoured update recently, but since I just got into the game now, I don't know what's new and what's not. I played several games this weekend, and my conclusion is that I prefer PS over HLL. Players seem to move more slowly, there's a stamina system, and around half of players are armed with bolt action rifles, which means there's less of a "spray and pray" focus than in HLL, where most people have automatics of some kind.
However, the action is still often pretty frantic and chaotic, and sometimes you have to spend a long time looking for a proper squad instead of just random players running around all over the map. When you find a good squad, it can be really fun though.
Yesterday had a great moment where I managed to survive a long time in a squad with good teamplay. The most epic part was when we had to cross a field under fire, and a Panther rolled up in support - orders were given to move directly behind the Panther and use it for cover as we crossed. Some doubts were heard on the chat as to whether this was suicide, but everybody joined in, and we actually did make it across under fire. Moments like that is what I play the game for.
