FGO is a turn-based game inspired by the Fate anime series. It has decent graphics, but terrible controls. The small file size and low memory usage make up for the slow gameplay.
Unlock heroes and fight
This game is very lax on your device, which is nice considering the detailed animation. Performance is excellent and free of bugs. However, the controls are super rigid and not beginner friendly. This makes for unforgiving gameplay as you cannot reverse any misclicks.
Or buy them
You should download Fate Grand Order if you’re a fan of the Final Fantasy series. The graphics and action may not live up to expectations but are still very enjoyable.
