Some more impressions. It's nice got getting destroyed all the time. I'm finally getting the hang of things again.
The new mantling cover mechanic. It's where you hop over cover and kick the opponent, stunning them for a few seconds. I like the idea for rewarding aggressiveness but it kinda sucks in execution. The enemy goes invincible once the animation starts, so they go right through your shotgun blast. It also seems to "suck you in" so even though I haven't even seen them move yet on my screen, I'm locked into position and can't move to get away.
There is a p2p structure built in for private matches for when the servers aren't available. Host advantage is definitely still a problem when not playing on the dedicated servers. I had a few lag issues, but nothing too horrible.
Weapons are pretty well balanced. The retro lancer is powerful but has quite a bit of recoil. The sawed off is brutal and can take out a few guys at once, but only has 4 rounds and takes forever to reload. Everything has it's trade offs.
There are some cool executions, but good luck getting to use them. Everyone steals your kills so you just have to keep shooting. I had a round with 1 kill and 6 downs. I've went to the darkside. Minus the final kill, if someone is down they are fair game now.
