Several days ago I signed up for Age of Expires II Definitive Edition BETA and one day I found few guys posting about AoE-2 DE BADGE in the forum while I was reading the posts in this forum https://forums.ageofempires.com
I registered for beta from some link in the email or forum ( I do not remember exactly ) and was searching the forum when I would get the BADGE / AoE 2 DE Invite.
I even posted in the forum asking for a BADGE. The Moderator ( RadiatingBlade ) helped me but I told him that I did not get survey for beta access.
Next I found a signup link on the main website https://www.ageofempires.com/
So, guys if you are wondering about Beta Signup
and finish your survey. I reported to the Moderator by posting in the post I opened, https://forums.ageofempires.com/t/insider-badge/38304/11 inquiring about the badge.
Now after finishing the beta signup at https://www.ageofempires.com/
I successfully finished the survey, I linked the steam account, also I uploaded DxDiag report.
So, I hope you guys find this post answers your questions.
