第二次超級機器人大戰G（第2次スーパーロボット大戦G / The 2nd Super Robot Wars / Dai-Ni-Ji Sūpā Robotto Taisen）於1995年6月30日在Game Boy平台上市，由Banpresto開發和發行，是一款單機回合制戰略角色扮演遊戲。遊戲的記憶體容量為4MB。除Famicom和GB之外，還移植到PlayStation、Game Boy Advance、PlayStation 3、PlayStation Portable、PlayStation VITA和3DS等主機。

儘管是第二部作品，但採用獨立的故事情節。故事架構以任天堂紅白機的第二次機器人大戰G為主。前半部分著重於《機動戰士V鋼彈》，後半部分則著重於《機動武鬥傳G鋼彈》。隨著這些變化，劇本也有所修改，包括關卡數增加和路線分歧的添加。《UFO機器人古連泰沙》將首次登場。操作以超任的第三次機器人大戰G架構，新增《機動戰士V鋼彈》和《機動武鬥傳G鋼彈》中的機體。

故事描述一位擁有超人智慧的傑出科學家卞佐爾達克（Bian Zoldark）。得知人類將面臨外太空勢力的威脅後，於是建造一個巨大的機器人Valsion來保護地球。為進一步增強力量，成立神聖十字軍DC（Divine Crusaders），企圖統一地球以對抗外星人，也因此引發地球的內戰。

儘管有許多人被迫或自願加入DC陣營，但一些超級機器人成功逃脫，包括鋼彈、無敵鐵金剛和蓋特機器人。他們以白色基地為據點，發動游擊戰，並號召各地盟友對抗DC。

最終，在DC戰敗後，超級機器人們也紛紛返回自己的地方。然而，他們無法忘記卞博士的遺言：“總有一天，另一場戰爭將會到來，就像這一場一樣。也許一年後，也許一百年後……”也為後續遊戲的發展埋下伏筆。

在遊戲中，可以購買物品，但通常使用後就會消失。遊戲中出現12種以上的機器人角色，包括Banpresto自創系列。

The 2nd Super Robot Wars, also known as第2次スーパーロボット大戦G (Dai-Ni-Ji Sūpā Robotto Taisen), was released on June 30, 1995, for the Game Boy platform. Developed and published by Banpresto, it is a single-player, turn-based tactical role-playing game. The game has a memory capacity of 4MB. Besides Famicom and GB, it was also ported to platforms such as PlayStation, Game Boy Advance, PlayStation 3, PlayStation Portable, PlayStation VITA, and 3DS.

Despite being the second installment, it features an independent storyline. The plot is based on the events of the Second Super Robot Wars G for the Nintendo Famicom.

The first half focuses on "Mobile Suit Victory Gundam," while the latter half highlights "Mobile Fighter G Gundam." With these changes, modifications were made to the script, including increasing the number of stages and adding branching storylines. "UFO Robot Grendizer" makes its first appearance. The gameplay follows the framework of the third Super Robot Wars G for the Super Famicom, introducing units from "Mobile Suit Victory Gundam" and "Mobile Fighter G Gundam."

The story revolves around the brilliant scientist Bian Zoldark, who possesses extraordinary intelligence. Upon learning about the threat of extraterrestrial forces to humanity, he constructs the giant robot Valsion to protect the Earth. To further enhance their strength, the Divine Crusaders (DC) is formed, aiming to unite the Earth against the alien threat, leading to a global civil war.

While many are forced or voluntarily join the DC, some super robots manage to escape, including Gundam, Mazinger Z, and Getter Robo. They establish a base of operations and conduct guerrilla warfare, rallying allies worldwide to oppose the DC.

Ultimately, after the defeat of the DC, the super robots return to their respective places. However, they cannot forget Dr. Bian's words: "There will come another war, just like this one. Maybe in a year, maybe in a hundred years..." laying the groundwork for future game developments.

In the game, players can purchase items, but they typically disappear after use. There are over 12 different robot characters featured in the game, including those from Banpresto's original series.
