The Darius collection is known for several key features that stand out. When you complete a level, you can choose to enter multiple levels. This gives the game a lot of replay value, requiring multiple playthroughs to see everything the game has to offer.

The Darius series is also known for its large biomechanical fish-shaped spacecraft. Unlike other games in the series, in Darius Twin, when you collect enough powerups, you don't lose them even if you die.
