Welcome to the Family

Heyo, people!

I will be brief. I want to collect as much info as possible about specific achievements and create my own database. I’m looking for information about the types of achievements that:
1. Require one to play / kill / beat someone who already has the achievement (viral)
2. Require one to do smth only on specific dates/time/day (date/time/day specific)
3. Require one to play the game in early access (early access)
4. Require one to play with developers (kill them, beat them, etc.) (dev req)
5. Require some specific devices or hardware (device req)
6. Or require some other specific conditions to obtain (random, game req and others)

If you have information about such achievements, feel free to post here.

Here is the full list of achievements I've already processed:
