A guild is a collection of players with the ability to request and send each other heal kits. Players discuss tactics, strategies and a bit of chatting and banter in the guild as they are able to communicate with each other on the guild chat.
A guild with 10 or more players also has the ability to participate in guild challenges. A guild challenge means that your guild gets matched up with an opposing guild of equal strength (based on number of average fans) in which the players in each guild try to beat each other. You will be rewarded in recruiter points for wins and draws in the guild challenge.
Those are pretty much the basics to what a guild is and the advantages of being in one.
