The achievement is unlocked when you
select the [DUMB] dialog and elect to skip the Hope yourself without ADA’s computational aid—the [Dumb] option is only available if the
player-character's intelligence is below average or minimum. The outcome of the action is a bad ending that does not count as a story completion. You will have to reload a save or auto-save created before this decision and request ADA skip the Hope to properly progress the story.
There are ways of decreasing the player-character’s intelligence if your player-character's build incorporated average or higher intelligence. The normal approach is to pop this achievement and, then, reload the most recent save and proceed with the story to unlock:
Adrena-Times syringes provide an effective means of lowering intelligence for this achievement. They are prevalent throughout the game. Each mega-creature will drop several as loot when killed. There are half a dozen mega-creatures in the vicinity of the
Fallbrook gate on Monarch if you need to farm them. Additionally, enemies on
Gorgon drop them insofar as they are related to the
Peril on Gorgon story.
Adrena-Times’ effects (increased movement & melee attack) wear off after 15 seconds. Afterwards, the withdrawal inflicts a -1 penalty to all attributes including intelligence. The withdrawal can be stacked 2 more times for a total of -3 to all attributes including intelligence. You must wait the 15 seconds after each Adrena-Times use for the primary effects to wear off in order to get the withdrawal.
If your character build set intelligence to very high, you will need to adjust it by -4 and stacking Adrena-Times can only get you a max of -3. There are two other ways to reduce intelligence. A concussion provides a -1 penalty to all attributes including intelligence. On supernova, this penalty lasts until the player-character sleeps aboard the Unreliable. If playing on a lesser difficulty, one can get the concussion flaw that will inflict permanent concussion with a -1 penalty to all attributes including intelligence.
The easiest way to get a concussion or the concussion flaw is to allow primals, especially the primal behemoth, to beat up the player-character. Primals can be found in
Emerald Vale and on
Scylla. Alternatively, if you have left a lot of mines undetonated, you can walk through them to get concussed or use them to get the concussion flaw. If working towards the flaw, it goes without saying, to make a save before you make a go for it either by using primals or mines. Reload the save continuously until you get the flaw.
Spectrum Brown vodka is readily available on Eridanos. If you have not started
Murder on Eridanos, you can quickly start it and find a table with half a dozen bottles or so as soon as you enter the hotel. This only takes a few minutes of play. Spectrum Brown provides Mind Attributes -2 that includes intelligence. Drinking more than one bottle increases its 2 minute duration by 2 minutes, with each successive bottle, up to a maximum of 10 minutes. Note that once the effects wear off there is a +1 mind attributes withdrawal effect that creates the opposite result to the one intended.
Once you have
below average or
minimum intelligence or a strategy to meet the precondition, proceed to the Hope’s main control terminal. (
If you want to get the Lost and Found achievement immediately following this one, this is where you should make a manual save if not playing on supernova).
After accessing the terminal, during the dialog, first say, “
I’m skipping it myself.” Choose either Terra 2 or Tartarus as the destination, select,
“[Dumb] Stand back, ADA. I know numbers real good.” This [Dumb] option is required for the achievement and is only available if the player-character's intelligence is below average or minimum. After some dialog between ADA and the Hope, a cutscene shows the Hope flying into the sun concluding with a “The End” banner.
The credits roll and the achievement pops.
The
video guide above begins on the Unreliable after the supernova player-character sustains a
concussion from a primal behemoth reducing all attributes by -1. This results in his very high intelligence being reduced to high. The guide shows traveling to the Hope and the dialog with ADA upon arriving. It, then, shows a way to stealth through the Hope with no enemy or sentry encounters—gathering an ID cartridge and bridge keycard along the way.
The player-character periodically takes
3 Adrena-Times waiting more than 15 seconds between each dose. This results in
-3 to intelligence reducing it to below average and satisfying the prerequisite. Though not necessary, just before the main control console, the player-character imbibes
Spectrum Brown Vodka (Mind: -2) further reducing intelligence to minimum.
The ensuing dialog shows the player-character’s choice to skip the Hope himself, popping the achievement when the credits roll.
Once you pop this achievement, you can then progress with the game. Load up the save you made at the terminal (or the most recent manual or auto-save if playing on supernova), and proceed with the game. During the dialog at the bridge terminal, allow ADA to skip the Hope. Regardless of how much you may have lowered the player-character's intelligence, ADA will safely skip the ship.
