One solution I've seen another wiki use is a small superscript note. This is true of the storyline[Subnautica only] and this is true of the storyline.[Below Zero only].

If Spoiler suffices to prevent story spoilers on this wiki, then a new template should suffice to prevent other-game spoilers.

It does depend on how we combine them. The two most basic options are to merge both the original and the Below Zero articles into one or to keep them separate and use parenthetical notes in the titles (e.g., Storyline versus Storyline (Subnautica) & Storyline (Below Zero).
