Union Arena, a trading card game developed by Bandai, has recently collaborated with Hypergryph’s popular free-to-play tactical RPG and tower defense mobile game, Arknights.
The Union Arena Arknights set (UA30BT) debuted in Japan on November 29, 2024. Each pack contains 8 cards priced at 385 yen (approximately $2.56 USD).
Like all Union Arena booster packs, you can pull a foil-stamped autograph card of the characters. The official website highlights the following autographed cards: Amiya, Kal’tsit, Blaze, Ch’en, Exusiai, W, FrostNova, and Talulah.
