the entrance to mothership is retarded

[asura]

why is it under the level? even with the compass i missed it by 1 block and died. ♥♥♥♥

it is but theres an easier option so you dont need the alien compass, just land six blocks from the right of the wall and youll get it eventually

If you hang from a rope directly above the entrance, you can guarantee that you're centered on the correct tile.

The entrance can also spawn on the left side. That’s why it doesn’t work every time. But like you said. You’ll get it eventually.

Where exactly that entrance is, is often a mystery and a bit hard to guess. Some say it varies between left, middle and right, with the sides being 5-6 blocks away from the level boundaries. (I'm not sure about the exact distances, and if it's PAST 5-6 blocks or ON the fifth/sixth block.)

Though if all you want to do is enter the Mothership for lore/characters, then yeah, you could try the last shortcut, and pray one of the spots is the one. Location of the exit-door doesn't seem to alter where the entrance is, so if you keep at it with one direction it's 33% chance every time.

Or pray for a Vault (those boxes with a shopkeep in em) near the Mothership so you can get in there (ussually via Mech) and bomb into the Mothership from it. Worked twice for me (first time i was rather confused and accidently left before doing anything of note).
Honestly, never managed to find that damn entrance the oldschool jumpy way. Be it carefully via rope or gliding down with a mech. I suppose my information was faulty since few can tell if it's on or past X blocks.

(If you're lucky, you could also perhaps find a hoverpack and hover dangerously close to the bottomless pit and try to bump into the entrance, from what i'm told.)
