Masked IO is an action shooting game that pits you against other players in a battle where survival and dominance rely on your skill and speed of thought. In the game, you will play the part of a masked warrior and fight other players in an arena-style setting, either in online play or in a campaign mode.

Masked IO is designed keeping in mind the competition in small battle arenas. Each player gets a set of weapons that they can use depending on their fighting style. The levels are created in such a way that they facilitate the players to maneuver around, utilize the available cover, and position themselves accordingly. It does not matter whether you play against other players or against computer players; there will always be something interesting for you in every mode of the game.
In the beginning, players join a game, and they are put right into combat from there. With the online version, players must battle each other for the best scores or to live the longest. With the campaign version, players advance through harder levels. The enemies get better and tougher, but players must get better at aiming and maneuvering around the battlefield. The game allows players to sharpen their skills, learn maps, and be quicker with their decisions in the heat of the battle.

Fans of fast-paced shooting games will enjoy playing Masked IO thanks to the difficult fights.
