A majority of Baldr Skys gameplay consists of reading the text that's rendered on screen and supported with audio for voices. The player will occasionally be presented with choices to select which may or may not determine the outcome of the game. As Baldr Sky has multiple endings, the player will have to replay the game multiple times in order to view all of the endings. Similar to other games in the Baldr series, Baldr Sky is also driven by a top-down 2D interface where the player controls a mecha in sprite form to combat enemy machines. The player is given a chance to upgrade or modify the equipment of the mecha prior to a series of battles.

Baldr Sky takes place in Japan some time in the future during the 21st century. Nanomachines have become commonplace and have taken a major role in society. The abilities of these nanomachines range from medical purposes for curing ailments and modifying the taste of food. A new generation of humans now also have a chip embedded in them which allows them to be connected to the Internet at all times. With the dawn of these new technologies, warfare has expanded beyond the physical world onto the virtual world. People engage in combat online in simulacrums, the name of the mecha units in the game, or with viruses (unmanned robots).

The story of Baldr Sky revolves around the male protagonist Kou Kadokura and is told through two timelines, the present and the past through flashbacks. At the beginning of the story, Kou is suffering from memory loss, so much of the back story about the past is told through flashbacks while Kou is recalling his memories with the aid of medical nanomachines. In the present, Kou and his subordinate, Rain Kirishima, are after a group of scientists who had inadvertently triggered a hazard due to leaking of a developing nanomachine. The city and the surrounding area that the lab is located in is ultimately demolished but the scientists had actually evacuated to safety from the lab before the place was destroyed. Kou wishes to uncover the truth about what happened that day and to prevent another tragedy from occurring again, as his girlfriend Sora was killed by the nanomachines.
