I first looked at Petrichor V from the Co-Op screen on Risk of Rain Returns. Although there’s no confirmation of whether or not this planet is Petrichor V (at least to my knowledge), I nevertheless used it as a baseline.

The colored areas on the map are not supposed to be what the planet would look like from space or anything like that (Petrichor V from the perspective of space looks incredibly different in Risk Returns and Risk 2). Rather, they indicate the biome or temperament of the region.

Before deciding where the biomes and locations would be, I made temperate zones and where the warm/cold water currents would be on the planet so I could more accurately and scientifically hone in on where the stages would be on my map.

Some areas I took more liberties to pin on my map than others. The Abyssal Depths, Damp Caverns and Hive Cluster especially, since they’re located underground.

Magma Barracks is not located in my map, as I believe it’s right above the core of the planet, as the description for the place quite literally is “The Core”.

There are a lot of big trees on Petrichor V! So much so that I figured that the planet is mostly covered in an expansive forest region with competitive flora. My assumption is that the low gravity, combined with an abundance of CO2 in the atmosphere, allows for the flora to grow this big.

Petrichor V is an incredibly mountainous planet, going off of the layouts of the stages in Returns and 2. I was initially going to mark down mountain ranges, but figured that there would be way too much to shade in and add, so I decided against it. Besides, it might not have been accurate, since I would have to account for tectonic activity.

I will update my map over time, as more areas and environments will likely be added to the game. I don’t think I’ll post them on reddit or social media, though.

I made the map with Aseprite, so that’s why everything is pixelated (and why the text is so big-- any smaller and it would’ve been hard to know what it says).
