Futuremark Games Studio today announced the first content pack for the zero-G shooter would be the free 'Moonrise' map pack containing four new maps all set around what's left of the Moon.

Although a release date for the Moonrise pack has not been announced, players who pre-ordered Shattered Horizon will be invited to start play-testing the new levels this week.

"Selected players will help us test the new Moonrise levels from a very early stage," said Antti Summala, lead designer. "Level design for zero gravity combat is a big challenge and we are looking forward to having real players help us create new experiences that cannot be found in other FPS games."
