gameplay ( mutiplayers, map, and communications)

1). i would love to hear about multiplayer, have a friend join me in exploring the map. or just a simple team battle, like territory( because that would be a reallife situtation.) supply capture. ect ... and How will the gameplay be between player to player??? will i have o invite a friend, or can i simple just walk around and come across a player???

2).How will big of a map r we talking about and will there be other "states/countries" we can travel to as we lv up??? im exspecting a huge ass map that will take like 1-2 weeks to memorize half. on that note; how will the boundries be setup, and Jumping/Climbing abilities pan out along with map elements and missoins???

3).This one is very important. say you can just come across player, how will communications be??? Chatbox??? will there be a mic downlad we can add on??? or how about supporting Xfire, so i can just use that as asource of mic usage??? I mean come on i know players love to communicate, how much fun would it be to randomly come around a corner and find a player being Ra[]Ded by a swarm of zombies and boss zombies, and then just simple watch and tease em, that would be funny as heck.( probably help out in the end)

P.S. I would love it for the selection class, that you set-up an; Farmer, Doctor, Military Sniper, and Explosive's Expert.

the game is an mmorpg , so it will be multiplayer at all times
