Hack and slash

From NWN2Wiki

Hack and Slash, commonly called Hack n' Slash, is a reference to a play style that is low on roleplay, and high on killing as many creatures as one can find. This increases the player's xp largely on their own efforts without relying on others, and if done well, can result in a high-level character in a brief span of time.

Hack n' slash can also refer to a server that is built to favor this type of gaming environment.
