Lineage 2 is a classic fantasy-themed multiplayer role-playing game. In the world of Lineage 2, players engage in a devastating war of the gods, leading to an unrelenting feud between the inhabitants of two continents. Humans, elves, dark elves, orcs, dwarves, kamaels, and artes fight for dominance over the lands of Aden and Gracia. Players slay monsters, hunt raid bosses, and explore the most dangerous dungeons. With the Keyran program, the gameplay becomes easier, providing the ability to automate various processes and become the greatest warrior in history. Monster farming, auto-leveling, auto-attack, autobuffing, and accelerated crafting become achievable through macros. The window binding feature is particularly well-implemented. Multi-window mode has become so popular that players have learned to create automated squads.
