In the Steam versions of Hiveswap and Hauntswitch, the player is able to get a number of achievements, some of which make reference to various tropes and jokes from Homestuck and MS Paint Adventures as a whole. The following is a comprehensive list of all the achievements, per act.
Here, the achievements are generally sorted by the order they can be achieved in the story. While this order is clear-cut for story-based achievements, it is less clear for missable achievements, as the rooms in which they can be achieved can be revisited throughout the course of the game, and some achievements only require the combination of objects, not an object and a background detail. This is in contrast with Steam, which orders achievements based on whether or not the player achieved them, followed by the number of people who achieved them, and therefore usually orders story-based achievements in order, but has the potential to switch orders of missable achievements at any time.

There is currently no known way to earn this achievement.
Judging by the description, it is speculated that this achievement can only be gotten when a save file from Act 1 is carried over into either the later acts of Hiveswap or Hauntswitch, possibly with a matching OURO achievement. This is also the only achievement to not be hidden, meaning that its description is viewable to anyone who hasn't achieved it, and even those who don't own Act 1.
According to Steam, all the achievement names in Act 1 are prefaced with a "greater than" symbol, ">". This is a likely reference to MS Paint Adventures, where the same symbol prefaces commands when they are clickable.
Only one person has received the BOROS achievement, Animegamer1996, but this is likely the result of developer tests.
Edit
in Homestuck.
