NieR: Automata turned out to be a sleeper hit for Square Enix, getting high praise from critics and selling well above expectations (over five million units to date) and becoming the best-selling game ever made by developer PlatinumGames. The game's runaway success even led to the remaster of the previous installment, NieR Replicant, released just last month.

However, on PC NieR: Automata was far from a good port. Luckily, modder Kaldaien came to the rescue with the so-called FAR (Fix Automata Resolution) mod, which even allows for texture injection. This, in turn, paved the way for texture mods such as GPUnity's HD Texture Pack, a project devoted to improving many of the game's low-resolution textures.
