Versions
The Saturn version of Gunbird was only released in Japan, however a version for the PlayStation did surface in the West under the name Mobile Light Force (complete with entirely unrelated packaging and removal of cutscenes) some years later.
For the most part, both the Saturn and PlayStation games are broadly similar, however the PlayStation has more intrusive loading sequences during gameplay, and lacks the "tate mode" option of the Saturn conversion, which rotates the game by 90 degrees to benefit from vertical monitors (which the arcade game was designed for). The PlayStation version also lacks the ability to save progress, and while some sound effects (most noticably speech) is seemingly played back at a higher quality, the artwork can appear darker and less saturated than its Saturn counterpart.
There are also very minor aesthetic differences between menus and the positioning of elements in the HUD.
