This was actually my second favorite Metal Gear game of all time. A shame most don't consider it canon. Other than having Mei Ling before Shadow Moses, it fits in perfectly with the rest of the series.
I never played ZOE. I just liked Gander because it just looked EVIL. Look closely, it's as if there are eyes staring into your soul. It just reinforced the notion that Metal Gears are mechanical manifestations of pure evil, and NO GOOD comes from them. Snake's daddy found that out the hard way when his got hijacked by TWILIGHT SPARKLE.
I really liked this game. They did a good job mixing elements of mgs with the original metal gears. And Yoji's designs are amazing. I'd be lying if I didn't say they are one of the big allures of ZOE 1 and 2
Awesome. I love the Metal Gear Gander. It's, like, the most underrated Metal Gear in the entire series. REX can suck it; Gander has two goddamn railguns, plus gatlings and drones. Badass death machine.
