The headline feature of this new playtest is the addition of Lua scripting for maps, which allows anybody to create scripted missions or game modes without touching any C# engine code. Any maps added to our content site will be downloaded when joining a server, which makes it easy to share your creations with others. We have made the tough decision to delay the previously announced IRC and translation features into a later release. This will allow us to focus our efforts on getting the next release out within the next couple of weeks. The main improvements over our stable september release are now:
As usual, the changelog contains all the details, including a list of changes that affect maps and mods. If you run into any issues or have any feedback, then you can create a ticket on our Github issue tracker or find us on IRC.
