Gameplay
All of the games are played from a third-person perspective, and the player must move around the massive battleground (using the analog sticks and buttons on the two gun controllers), while using the Gun Controllers to aim and shoot at enemies. The goal is to survive and shoot down the rival teams to decrease the opposing team's team meter within a given time limit. The round ends when either teams' team meter drops to zero and/or if the timer reaches zero.
Players can switch weapons in-battle, utilizing various strategies and tactics, by melding the two gun controllers together into different positions, such as:
Story
In 2115, the country known formerly as Japan has been split into two parallel worlds: the Frontier S (Stratos) and the 17th Far East Imperial City Management District. Frontier S is an outlaw universe in which freedom runs rampant, while the 17th Far East Imperial City Management District is a totalitarian universe completely bereft of freedom and is under constant surveillance. When the two universes are starting to fuse into one, the government of each worlds initiates the Operation Stratos, a world-scale protocol wherein a handpicked group of gunslingers, mercenaries, and special individuals, each from the two universes, will be sent to the year 2015 to alter the past by eliminating the other side until only one group survives, erasing a parallel universe in the process.
The story revolves on a group of gunslingers, each from the two universes who participate in Operation Stratos, particularly on a group of four childhood friends: Tohru Kazasumi, Kyōka Katagiri, Kyōma Katagiri, and Shizune Rindo, who all must confront their own flaws and differences when they battle their alternate selves in order to survive.
