Or is it just me?

This game is free. It also says on its store page a bunch of false nonsense. When did BloodDome start "it" all? When did BloodDome come out on the arcade? It's pretending Vampire Survivors is secondary to some original arcade game called BloodDome. I can tell the difference, the average person who doesn't know much, probably not. Retro callbacks and retrofuturism is fun, but you can do that without making your game appear what in fact it is not....

can someone make a list of all the items so i can get the hardest achievement

is a really shady and awful practice you've got going on. game in virtually unplayable until you input your email address. i encourage everyone not to do this with your actual email/s and instead, use a burner email.

Yes. Blood dome 99. Yes. Paper plane. I've seen the trailer, I don't need to hear it all the time.
