Shinseiki Evangelion 2 (新世紀エヴァンゲリオン2), localized as "Neon Genesis Evangelions", is a Japanese video game for the PlayStation 2 which was developed by Alfa System and published by Bandai. It has RPG and world-controlling elements, and allows the player to follow a number of characters through multiple variations of the main plot of the Evangelion anime.
The player controls Unit-01 walking around a large map until they run into an enemy. The player is then given a list of action commands which they can choose to attack the enemy. Once one of the action commands is chosen, a sequence will be shown, created by CGI, depicting the attack. This was one of the most praised elements of the game. The game also has story arcs in which the player has a list of playable characters to choose from. For example, the three main characters Shinji Ikari, Rei Ayanami, and Asuka Langley Soryu, are available from the start with more characters unlocked as various game events are triggered. There are 11 scenarios in total, but none are considered canon to the overall series.
