Kingdom Conquest II (Japanese: キングダムコンクエストII, Hepburn: Kingudamu Konkuesuto II) is a Massively multiplayer online strategy game with incorporated city-building, card collection and third-person action gameplay elements, developed and published by Sega for iOS and Android devices in 2012.

The game will be ending its service on 31 August 2017 13:00 Japan time, and its sequel Kingdom Conquest: Dark Empire is being developed.

These Card Packs can either be purchased through In-App Purchases or with tickets obtained by running Dungeons in a 3rd Person 3D Dungeon Combat system, where players fight successive waves of enemies, or it can be obtained with challenging the rivals in the Arena to gain the draw ticket for the monsters.

In this way, players must vie for control over areas of the map, with the ultimate goal of conquering Debris Towers, enormous Spires filled with Monsters.

In the dungeon mode for the Kingdom Conquest II, Ninja and Saint were added as the new character classes since the prequel.
