I'll leave a copy of the FAQ here:
Labyrinthos Play Test FAQ

Q: Which Characters are playable in PvE
A: Currently the characters which were playable when the official servers closed are playable, we plan to add the other characters in future updates.

Q: Will my characters start 1*?
A: No, when you purchase a character they will auto-start at 5*!

Q: Will Keys be consumed when playing PvE matches?
A: No keys will be consumed when playing matches, we are currently discussing what we wish to do with the key system as the old system was very unfriendly to players.

Q: Do the PvE matches have the same length as on the old servers?
A: No, we have made some small changes to PvE, this being one of them. We have changed the amount of days which need to pass before the research centre opens based on difficulty.
Easy = 12 Days
Normal = 28 Days
Hard = 17 Days

Q: How do I make an account and what information do you collect on me?
A: When first opening the game you will be prompted to allow the Discord Application "Black Revival" to view your "username, avatar & banner". This allows us to see your public Discord ID to create and link your game account to your Discord.

Q: I am running BlackSurvival.exe but the game keeps closing
A: Please run Project Lumia Launcher.exe to start the game!

Q: How do I earn Gems, Gold & Bear Points?
A: When completing matches in PvE you will be rewarded a certain amount of each resource depending on your match score.

Q: Why do the content creators have so many resources?
A: The content creators were given a large amount of resources during the early testing phase to be able to showcase systems and skins to their audience. None of their resources will transfer past this period.

Q: Can I make videos or stream this playtest?
A: Yes, we don't have any restrictions in place for sharing content from this playtest period

Q: Will PvP be added in the future?
A: Yes, we plan to add PvP in the future. Our current estimate is that it will take roughly 6 months.

Q: How long can I play the game for this weekend?
A: This weekend the servers will be open from October 28, 2023, 10:00 am., 10:00 until November 1, 2023, 3:00 pm!
Times for next weekends playtest will be posted in the coming days.

Q: Can I play on mobile?
A: Currently you can only play on PC. We are hard at working adding compatibility for the mobile client, but we have no ETA on when that will be finished.

Q: Windows Defender doesn't let me run "Project Lumia Launcher.exe"
A: Windows defender flags the program as unsafe due to it not being digitally signed with a certificate, you may need to disable Windows defender to start the game
