Metal Gear Mind F**K: Groznyj Grad is in Zanzibar Land
All the Metal Gear Fans ought to get a kick out of this. IDK if anyone else has noticed this or not, but if you pay attention to the Geography of the series, Specifically that of MGS3 & Metal Gear 2: Solid Snake, you'll make a startling revelation. One might even call it a Mind F**k.
Metal Gear Solid 3 takes place in at Groznyj Grad. It was a Soviet Military Fortress Dedicated to advanced weapons design. It is located in the fictional Region of Tselinoyarsk. The game States that it is located in Central Asia on the southeast border the Soviet Union, roughly where current day Tajikistan is. In the Briefings they state that it is a Mountain jungle area with desert to the south.
Metal Gear 2 Solid Snake Was set in Zanibar Land a fictional Fortress Nation Built by Big Boss. It's Mountainous Jungle area with Desert's in the southern Region. the game also states that it was was bordered by Afghanistan, China, & Russia. That places it roughly on the Southeast Border of the USSR, in roughly the same spot as Tajikistan.
If you analyze the data you'll Realize they are set in the Same Geographic Location. They ALSO Share the same environment. That lead me to the conclusion that Tselinoyarsk (which Groznyj Grad is located in) & Zanzibar Land are, in fact, one & the same back when Metal Gear Solid 3 came out.
Also if you think about it in the context of the story it makes sense as well. Zanzibar Land was founded where Snake was forced to kill the Boss & Big Boss was born, metaphorically speaking. Zanzibar Land was founded as a place where soldiers were free to control their own destiny unfettered by allegiances, political or otherwise. This also happened to Big Boss' interpretation of The Boss' Dream. Poetic if you ask me. What better place to start than the place where she died giving birth to Big Boss?
