とても長い間答えを探しました, 自分のリプレイを見直した 20+ 回, しかし、私はこの実績を達成できませんでした.
Yesterday I accidentally came across the answer inside the game itself,
and went to create my FIRST GUIDE in my life.
And for this achievement you no longer need to watch replays.
Although this is written about in most Guides on the Internet, but they are already outdated.
soo..
1. Now you need to click on the “SOCIAL” ボタン
2. クリックしてください “友達” ボタン
3. Select a friend with the game installed, he must be online and play any mode so that you can watch him in the “SPECTATE” モード.
As soon as you switch to this mode, you will be given this achievement.
