Now that the Mod Shop is available in all My Colony 2 game clients, I realized I haven't made an explicit post on how to submit your mods to the shop. It's actually fairly simple. The first thing you need to do is sign in to the mod shop portal with your Ape Apps Account:
https://modshop.my-colony.com/
Here you can manage your public modder profile (which people will eventually be able to view from within the game) and manage your mods. You can click on the + icon in the toolbar to start a new mod project.
The details are all explained and straight forward. Note that in order for your mod to show up in the store, you need to provide the mod file, and at least a mod icon or screenshot. The mod icon should be 1024x500px in size.
I still have work to do on the mod shop portal, eventually you will be able to see usage stats, download trends, and read feedback and reviews (as soon as I get the feedback and review functions added to the game).
