Boosting is cheating to rank up, basically.
You play the game online and rank up to open it.
Use good guns and practice so you get bette at it. I think in te bottom left ofthe screen there are challenges. Do them and that will nake it go up faster :]
In the special ops, you just level up your level to like 25, and if you spend more cash, they get riot shields :D.
No, you need to rank up your gun level again.
Yep. You can go to lobby leaderboard and look up your statistics.
creating the masterpiece for each rank
No you cannot. You can only go up to 2 players.
more than planty go to gamebattles.com and you can sign up as free agent and be picked up by a clan.
You cannot loose rank. Once you obtain a rank up you cannot go back down.
you need to go on ranked match rather than player match to earn xp and rank up
you will have to go to the villige chef and there will be alot of quest including rank 1,rank 2,rank 3. and when you finish all the rank(1) quest you level up to H.R 2 and so on.
