Transistor is a science fiction action role-playing video game developed and published by Supergiant Games. The game was released on May 20, 2014, for Microsoft Windows and PlayStation 4, on October 30, 2014, for OS X and Linux, and on June 11, 2015, for iOS devices. Transistor sold over 600,000 copies across all platforms by January 2015.
Transistor utilizes an isometric point of view. The player controls the character Red as she travels through a series of locations, battling enemies known collectively as the Process in both real-time combat and a frozen planning mode referred to as “Turn()”. Using Turn() drains the action bar, which refills after a short delay. Until it is full again, Red cannot use Turn(), or almost any other ability. Red earns experience points after each battle, and may collect new powers (called Functions) from fallen victims of the Process. Functions may be equipped as one of four unique techniques, as an enhancement on another, equipped technique, or as a passive, persistent effect during battle. For example, the Function Spark() may be used to fire a wide area attack, equipped on another Function to increase its area of effect, or used as a passive effect to spawn decoys of Red. Red can also collect and activate Limiters, which serve as optional debuffs during combat, but in turn increase experience gained. Both Functions and Limiters reveal minor parts of the story if used for a long enough time.
For the PlayStation 4 version, the DualShock 4 light bar flashes in sync with the Transistor’s speech.
