i have no choice but to play this cuz ijji removed gunster.
i was wondering if anyone play this game. i need to know if the bubble gun/robot character/laser gun is obtainable. you can get the license thing for those 3 from the missions. i randomly click around to see if the bronze medals work for those license but an error msg pops up and kicks me back to the menu of gunstrike.
