Modders
The modding support is finished and it'll be released in the next update, so if you're a modder and you're interested in making a mod for when the update gets released, then check out the guide here, all mods sent to us will be uploaded to the apocalypse's workshop ready.
Players
There's a huge amount of content modders could create, and there'll also be scripting support, so if you've got any map requests or map ideas post them in the discussion linked below! Everything that is created before the update comes out will still be uploaded on the workshop by us, so don't let that stop you.
