 The name of "Embark Studios" was unfamiliar for me at first. But by some searches on Google, I found they are "old friends".
 So I write this blog and want to make a contribution to them.
 
-The team of Embark Studios came from EA and DICE. They made "Battlefield" which I spend lots of weekends at high school.
-I can't forget the feelings of reversing the situation in "Battlefield". Usually, in the beginning, we stay at the last control point.
-enemy's helicopter was hovering in the air. Lots of vehicles rush in. With the cooperation, we go through the defense hardly.

 I miss those guys who fought together. And the investor of Embark is familiar too. "NEXON“ made "Kart rider" which I played a lot too.
