Chain Chronicle

Chain Chronicle combines three gameplay elements: tower defense, traditional role-playing and card trading in the form of Arcanas. The role-playing game elements drive the entire story, allowing the player to make decisions, visit towns and participate in events. The map system shows the towns and areas that the player must visit by tapping on one town to another, however for the player to get to the next town, it must clear some enemies first. Battle in the game is similar to a traditional tower defense game, each player can command a team of four Arcanas, with two more as sub-party extras and a guest unit.

Each Arcana is assigned to 5 classes, and each unit are weak to specific class. In the second versions of the game, updates introduced Fighters and Gunners, with the former being a type of Swordsman, and the latter being an archer-type.

The continent of Yggdra (ユグド, Yugudo) is a place where humans, ogres, giants, forest sprites, and many more mythical creatures live. Led by the Holy King, the continent was at peace until one day, a mysterious group called the Black Army (黒の軍勢, Kuro no Gunzei) appeared and started conquering the land. In response, the Holy King and its troops fought against it, but Holy Capital fell and the Holy King was killed by the mysterious Black King. As the continent was in the glimpse of destruction, hope glimmered as one man decided to fight back and formed the Volunteer Army to oppose the Black King and bring peace back to Yggdra.

The game was met with positive reviews upon its first month of launch. Gamezebo praised its grid-based combat mechanics, number of characters, and extensive story, but criticized the serialized female character designs, saying "...the portrayal of women in Chain Chronicle is completely, and frustratingly, stuck in the past." Despite that, Gamezebo concluded "[e]ven though it has a few blemishes, they don't stop the gameplay from being fun and rewarding". 148Apps praised the game for its gameplay and fair free-to-play system, stated that "Chain Chronicle is an easy-to-learn role-playing game that successfully combines tower defense, strategy, and action".
