Kritika: The White Knights

Kritika: The White Knights, previously Kritika: Chaos Unleashed, is a hack and slash MMOG RPG for Android and iOS. It was developed and published by Gamevil in late 2014, early 2015. The game is setup around micro transactions.

The name Kritika may come from the Czech, French, German, and Russian word for critique, or it may be a play on the word critical, as in a critical hit, which often used to indicate a stronger than normal attack in video games.
