How to Play Defenders of Dynatron City
Quick start
Move with the D-pad and use A for your hero’s normal attack. Press or hold B for the character-specific special power; flying abilities require holding the button. Open the item-adjust screen with Start or Select, use Up/Down to choose an option and Left/Right to browse heroes, then A to confirm. Try Buzzsaw Girl for mobility and keep another healthy hero available for difficult rooms.
Controls
D-pad: move left/right and climb or move vertically where allowed. A: normal attack. B: special power; hold it for sustained flying powers. Start or Select: open the item-adjust screen. There, Up/Down changes option, Left/Right browses heroes, and A selects a hero, opens/closes the map, or uses a supercharger depending on the highlighted option.
Defenders of Dynatron City — About this game
Defenders of Dynatron City sends a six-member superhero team through streets, a mall, sewers, a cola plant, and Dr. Mayhem’s lair. Each defender has a different normal attack and special ability, from Jet Headstrong’s detachable head to Buzzsaw Girl’s rapid movement. Heroes can be changed from the item-adjust screen, which also provides a map and a temporary supercharger. Missions run on a timer, so choosing a character suited to the next obstacle is part of the action.
