| Game update | パッケージ版発売開始! 秋葉原にある 『レトロゲーム・PC専門店 BEEP』さん にてパッケージ版を発売開始しました。パッケージ版の予定はもともとなかったのですが、BEEPさんのご提案により、非常に面白そうだと強く感じ、発売となりました。 今回は原作の『地底最大の作戦』がI/Oカセットサービスとして、カセットテープ版にて販売されていたので、カセットテープをパッケージとし、中にダウンロードキーが記されているという形式を採用しました。このアイディアもBEEPさんよりいただきました。 現在、レジの上に展示してあるディスプレイにて本作のPVを流していただいているのですが、このディスプレイのすぐ下の柱に、パッケージ版が掛けてありますので秋葉原にお立ち寄りの際は是非、お買い求めください。 | — |
