I'm working on the expansion for the recent Wasteland biome. My plan is to make 2 packs for this biome - the one focused on the land area, and the other one expanding the coastal/shore part of it with sheer cliffs and possibly some structures we talked about with Manuel in the comments some weeks ago.
I'm starting with the land based area - it should be compatibile with A, B and C sheets of the Wasteland Coast letting you make half water based / half land based sheets arrangements, which may be interesting in terms of scenarios.
Next week I will work on something fully different, unrelated to Wastelands, but I will get back to it by the end of the month with another set, because I would like to increase the list of biomes with a lot of cross-compatibile map packs - so far those are mostly grasslands and winter themed maps and to some extent deserts. Also ferrocrystals and blue planet in terms of more alien worlds.
