Are you of the mind that Warhammer 40,000: Eternal Crusade jumped into alpha a little bit too early? A new state of the game dispatch from the development team explains that having the game in its current alpha testing isn’t slowing down design but is instead helping to train the team for the future development environment on a live title. Players can start finding bugs and the developers can start refining systems earlier by keeping a small team on live updates while most of the team works on the larger developments.
Keeping a single map in rotation at the moment is meant to have a similar impact, with players fully exploring and refining one map before the next one enters the playspace. A more robust lineup is planned for the future after the designers know they have several polished maps. It makes the current rotation a bit bland if you don’t like the map, but hopefully the final result will make the game more fun to play.
