How to Play Twin Action

Quick start

Move clear of the nearest approaching shots.
Use ordinary fire to clear an approach.
Watch ground targets as well as enemies crossing the screen.
Use the stronger aura attack when extra coverage is needed.

Controls

Use the directional controls to move the aircraft and evade incoming fire. Use the two action inputs for ordinary fire and the stronger aura attack; their physical assignment is not inferred from the generic Button 1 and Button 2 labels.

Twin Action — About this game

Twin Action places its twin heroes in a shooting challenge with multidirectional fire and attacks against ground targets. The weapon coverage helps with enemies approaching along different paths, but the character’s vulnerable area makes narrow gaps dangerous. A separate aura-like smart attack provides a stronger response when the screen becomes crowded. The useful approach is to create space with ordinary weapons first, then reserve that stronger attack for a formation that would otherwise close the route.
