The MG Tallgeese is great, I honestly think it's one of the best Gunpla models out there.
The balance of the parts, the sturdy proportions that aren't too thin, the gimmicks and range of motion... of course there are some things that bother me, but they're minor compared to the good points. I never get bored of building it, no matter how many I make.
This time, I'm using the leftovers from mixing the Tallgeese F to make a normal Tallgeese, and then playing around with strengthening the armament and creating an original paint job.
To be honest, I don't really understand the design of the Dover Gun, but I guess it's roughly defined as a cartridge-type beam cannon.
In the game, it uses real ammunition.
