This project covers the development side of Artemis (https://www.artstation.com/artwork/L3DoQw).
Artemis is a deathmatch arena map designed for Unreal Tournament 4. It makes use of advanced mobility, key pickup decision making and narrow long range corridors.
There is more detail in the two videos at the head of this project, but the TL;DR is that this project was designed to have smooth player collision and clear sight lines to make play the priority. For ease of construction many mesh blueprints were made, and some were expanded to be movers to add some dynamics to the map to give the facility life.
