The only other information we have is a brief teaser, which you can see me discussing here with my thoughts and hopes for the game, and the series as a whole:
It appears there are now “biomes”, kind of like the separate tank concept that the original AbyssRium tried out, but these biomes are all visible on the same screen giving a much more cohesive feel (and presumably, far less loading screens). Many of the coral and fish look brand new, though I spy a few reused assets already (hello Blue Whale).
It’s interesting to see AbyssRium World seemingly coming out so soon after AbyssRium Pole. If World comes out of pre-registration in 4 months like AbyssRium Pole did after it’s pre-reg period, Pole will have been out for less than a year.
Rest assured I’ll have video and written guides for AbyssRium World as soon as I am able to make them. I do NOT have any affiliation or contact with Flero Games or Idle Idea Factory, so I will probably get the game the same day everyone else does with no advance knowledge, so bear with me when the time for guides comes!
