Mega Man Star Force 2

Mega Man Star Force 2 is an action RPG much in the same vein as the first game. It is rendered in an isometric style (sprites, views, etc.) during field gameplay, but its battle system is three-dimensional, with the battles being viewed from behind Mega Man, and movement restricted to only left and right. Since enemies have a much larger playing field, battle evasion seems limited, but the player is given a choice of techniques like shielding and homing attacks to keep battles balanced.

Mega Man's life is a simple "Hit point" (HP) numerical system. When he takes damage, the number lowers, and when it reaches "zero," the game is over and the player must restart from their last save point. HP can be recovered in a number of ways, both in and out of battle. The player can also use their standard Mega Buster at any time to combat with, and upgrade items for Omega-Xis can be collected throughout the game to increase the Mega Buster's rate, power, and charge speed.

The game stars a fifth-grade student named Geo Stelar, and his AM-ian partner, Omega-Xis. Set approximately two months after the events of Mega Man Star Force, Geo has adjusted to life with Omega-Xis, and has made many new friends. At the beginning of the game, Geo is eager to receive a new transfer known as a Star Carrier that he has waited two months for.

One day, Geo and his friends decide to travel to the technological hub of Wilshire Hills in IFL City, where they witness a new device known as the Star Carrier at work. The Star Carrier is able to take radio waves and transform them into material objects, known as Matter Waves. While watching a movie, Geo and his friends witness an attack by a mysterious man named Hyde, who partners with an Unidentified Mysterious Animal, or UMA, named Phantom in order to wreak havoc. After fusing with Phantom, Hyde becomes Dark Phantom. When Dark Phantom is defeated by Mega Man, he flees, and from that point forward becomes one of the game's antagonists.

About two months following the CoroCoro Comic announcement, the Shooting Star Rockman Ultimate Navigation Legend Guidebook was released in Japan. Inside of it, the first details about the game were revealed through an interview with series director Masahiro Yasuma. Along with the interview was a silhouette of a new sword-themed transformation set to appear in the sequel (later revealed to be the Thunder Zerker form). Many elements from the original game remain intact including the roles of Geo Stelar (Subaru Hoshikawa in Japan) and Omega-Xis (Warrock) as the protagonists and the prominence of the Brotherband System. However, the interview made mention of more advanced transformations, freer movement in battle, a strong rival character for Geo (revealed to be Rogue, a wave human who gets his strength from loneliness, the alter ego of Solo, his human form), and online battles using the Nintendo Wi-Fi Connection.

The interview also noted that the game's production was roughly 30% complete at the time and was expected to be released winter 2007 in Japan.

The two versions of Mega Man Star Force 2 were the eighth and ninth best-selling video games in Japan during their week of release, each selling 37,000 units. Both versions combined sold approximately 225,221 units in Japan by the end of 2007 and a total of 291,962 units in the region by the end of 2008.

As for critical reception, the game fared poorly. Common phrases used were "more of the same" and "unchanged." Likely referring to the lack of advancement in graphics or game play. The third game toted similar reviews, with below average scoring and the same complaints.
