GUN PRINCESS ZERO
The cold war is underway! Unluckily, the enemy don't just sit around threatening you, they've armed four nuclear missiles in secret, planning to wipe out the big city in one fell swoop! Marching into the enemy territory to stop this would lead to a full-scale world war, so instead a single soldier is dispatched to sneak behind enemy lines and fight her way to each missile and disarm it.
Bring on a wide variety of guns and bombs to crush all opposition! Intense platform action in a world with hundreds of rooms to explore! Completely freeform metroidvania action where discovery is the only way forward and you get to decide in what order to take on challenges completely on your own!
