I was given a task of creating a symmetrical multiplayer map for 6-10 players in Unreal Tournament. Deadline was 3 weeks. I started with researching concepts and strcutures but had a clear vision of where my main inspiration would come from. That was Mattisborgen from the old classic children's story Ronja Rövardotter. The castle in the movie has been struck by very strong lighting and been split into two. I started out with white boxing(blocking) to get a feel for the flow and length of the actions of the players and passages throughout the map. After that felt really good, I playtested with specific amounts of players and then made adjustments from the reports of those players. Then I went through all the art assets and started replacing the BSP. This was an interesting task since I didn't know what assets I had before working on the blockout so I had to adapt the flow and layout to what assets were presented to me later in the project. This I believe is a challenge not to take lightly so your starting work has to have that in mind. Never be unprepared to change and compromise.
The map was published on the Epic Games Unreal Tournament forum and so appreciated that it was pushed through all of the Unreal Tournament's official social media outlets.
