Gaming Mode
Action games usually offer Room gaming mode, which is also what players think of most of the action games. We can say that action games like DNF, C9, Dragon Nest and Mabinogi: Heroes all integrate the Room mode.
Outdoor maps are also featured in TERA, and the in-game stories mainly take place in outdoor areas(Tera online Gold). This game can be said to be the sole action RPG featured mainly on outdoor content in the game history.
Graphics
With the application of Unreal Engine 3, TERA presents the audience with glaring and natural graphics, as well as delicate and impressive characters.
Another important thing that I have to point out is that the sexy female characters in TERA(Tera Gold) are rendered perfectly, which are also one of the most charming female character series I've ever seen.
