A being known as Lina has begun absorbing data from an interdimensional network of servers. The "motes", sentient computers who oversee the network, prepare a fighting tournament and summon heroes from many dimensions to participate. The motes hope to awaken the tournament's winner as the "Blade Stranger", a legendary hero who can defeat Lina and save the network.
Gameplay in Blade Strangers takes place on a 2D plane and uses four attack buttons. The game avoids the use of more complex input motions seen in other fighting games such as quarter-circles and dragon punches; instead, players use a single directional input combined with a button to perform their moves, similar to the Super Smash Bros. series. During battle, players can build Heat to unleash powerful "Heat Up!" super moves against their opponent.
The game offers a single-player story mode, with characters interacting with one another while progressing through an arcade-style tournament ladder, along with training and mission modes. The game also supports local and online multiplayer battles.
Blade Strangers features twelve playable characters drawn from different independent game franchises, primarily other Studio Sanzensen and Nicalis works, along with two original characters for a total roster of fourteen. Each character also receives a stage based on their game of origin.
