After watching for a while, Bill was gradually getting hooked up, fascinated at how the players displayed their skills.

The solid defensive fortress and the powerful firepower repelled the invading zombie hordes one after another. The game's difficulty was supposed to be very hard, so the players showcased their remarkable talent to render a superb performance.

Vivian smiled and said, "Dad, Darren is on a different level than the rest when it comes to gun proficiency. After all, he is the top professional player. That's why he's awesome!"

“Gun proficiency?" Julie showed a puzzled expression as Vivian threw the term around.

In the current version of Wasteland, the players’ most important weapon proficiency is the gun proficiency. Remember when I said that my account is in the Diamond Division? My current gun proficiency is Level Five-61%."
