The first thing Sam did is not attack the people that came at him.
Instead, he swiftly activated his earthen wall and surrounded himself with it. He made the wall sturdy enough to not let a single attack pass through.
He is being attacked from all the sides by various attacks, but all of them are in vain.
Not just Sam every other player also did the same.
They all went into a defensive position immediately and protected themselves from the attacks.
Even though the rules of this task are pretty straightforward, things are not as easy as they seem.
In this game, players are spread all over the place and the person with the highest kills wins. And to reach that goal, a player could do two things.
One is to make it easier for him to kill more people and the other is to make it difficult for the other players to kill.
