Originally released as commercial game (download-only), the game went free-to-play in September 2011. However, the implementation was more similar to shareware: players could play the game for free, but were restricted to ships of the first level. The rest of the game was unlocked after buying a premium account. In November 2011, the game officially reverted back to beta status in order to restructure the game for the new business model, including the implementation of an item shop. In February 2012, the business model was reverted back to commercial and the game was made available as paid download from various download platforms. At the same time, the second beta status was abandoned.
