I don't know if someone has opened this thread yet but I want to share a little detail I found.
On mosaic lines, once both temples are completed, after using the shrykull to kill sligs, before returning to rupture farms there is something interesting. There are some wooden boxes and some green bottles and, yes, I think that they are Soustorm brew bottles!
What do you think about?
I think that the initial propose was to confirm the next game, or to complete the story of Oddworld. It could mean that while Abe is on Rupture Farms, Soulstorm brewery is opened.
