So I've been playing through the game for my first time and like always I choose one weapon to max out at a time, this time it was the VZ61 Machine Gun. I just recently maxed it out and unfortunately, the gatling gun didn't show up in the item buy screen. Any tips? Do i have to beat the game in order to get the gatling gun? I haven't beat it yet becuz I've been waiting to pwn those two gatling gun majini with my own....
