Story related achievement and likely will be the first achievement you get. But if you are like me, you check TA first for achievements, want to know the first one available that is quickest to get, and want to know how long into the game you will play before you get your first achievement. This is written towards you.Quick Version:
Exit the first room you spawn in and head right pressing to jump and double jump as necessary to get to the first door. Then, keep heading down until you find an exit to the Promenade of the Condemed. At least the first few times you spawn, this will probably be in the lower-right area of the map. Follow the in-game currency purchases and NPC conversation prompts until you exit again to the actual Promenade of the Condemned map.
The game procedurally generates every level and where some hidden areas are with each respawn. So the locations of the Promenade will change each time but I have found the exit around the lower right of you map accessible by hitting
If you rush, you can get this achievement within 3-5 minutes of starting the game for the first time. Climb chains and use
to jump down through non-solid floors to go downward and climb/jump up as needed to navigate each level.
In your starting location in the dungeon, depending on how the game generated hidden items, you can also unlock this within one minute right at the start.
Once you have entered the Promenade of the Condemned exit you found in the starting dungeon map, you will come into a red room where there is a large figure where you have to spend all of your cells you currently have on upgrading items you are currently holding or have access to. You have to spend all of your cells by highlighting what you want to put them towards with your left stick, then press
to spend a Cell. You have to spend all before the next door will unlock.
After the next door, speak to the next NPC to choose which perk you would like to have active before going into the next area. Once you have done this, filled up your health with the big beaker, then hit
to finally exit to the Promenade of the Condemned. Once the map has loaded, the achievement will pop.
I will add some screenshots as a visual aid for those that prefer it or are not used to Metroidvania games like myself.
If you have feedback, let me know before you downvote.
