Ultra X Weapons / Ultra Keibitai is an arcade game which is known by two different names. This suggests either a regional release variation or a potential change of title during development or marketing. Without further information, guessing the gameplay or the developer is difficult. The double titles suggest the game might incorporate mecha or futuristic weaponry, hinted at by 'Weapons' and 'Keibitai' (likely relating to a military or special forces unit).  More detailed records are needed to confidently discuss the game's specific features and reception.
