Hello WiseMonster. Completionist.me is a website used to track your own statistics. There is no leaderboard feature, and therefore users aren't banned for "cheating" their achievements. You don't need to do anything special to join, and you will not get banned.

Two Assassins Creed games have recently received achievements on Steam. Unity's appear on completionist but Syndicate's do not. Do we know the reason for this?

Updating the profile of a user that has achievements in the game will add them to the website. I went ahead and did that, so the achievements for Syndicate should show up now.

It's a personal tracker for achievements.

C.ME was temporarily down. It's up and running again.

What makes you think it's related to Out for Blood?

A lot of users have experienced a drop in AGC as of late because of Zonitron. Check this thread Light made, and see if you've played any of the games on the list -

Hey! Thanks for dropping the keys.

Sadly it would seem they are all redeemed already. I wish people would write if they took a key.

hello guys is the feature of changing time zone setting implemented? It would be nice that hours on which I unlock an achievement would correspond in both steam and Completionist. Thanks!

Hey! Soon there will be a way for users to manually change their timezone. In the meantine, if you tell us your prefered timezone and drop a link to your profile, we can manually change it for you.

Try manually updating Portal by going to the game page and clicking the icon in the top right. http://i.imgur.com/0pQOStQ.png If you're already tried this, I'm drawing blanks.

I've contacted the site admin to take a look at your profile.

Sounds good. To get those achievements tracked you'd either need to family share them again / buy them.

Because you're still missing 22 achievements on c.me. Did you try every single method listed on the recovery page?
