EXTRA: Space 54 Achievement in Vampire Survivors

Golden Fingers are a very rare drop that make you invincible for a time and increase enemy amount by absurd levels and make your weapons fire constantly. This achievement requires you to pick up five of them cumulatively. Thankfully, there are five on the map in Astral Stair. If you've been completing all DLCs in order, you'll already have that map, but refer to EXTRA: Astral Stair (5G) if you don't, and grab the map for it in EXTRA: Astral Stair Map (5G). With it, you can pause and see all five Golden Fingers on your map. Use the teleportation doors to travel to each Golden Finger and grab it. Once you've gotten five, you can end your run to get your achievement (no other achievements in this DLC for this map).
