The online game Btooom! was developed by Tyrannos Japan for the DXBOX 720 (an obvious pun on Xbox 360). It is a science-fiction, third-person "shooter" that involves killing your opponents with bombs, known as BIM. In System Link, up to 8 teams can fight at the same time. The players must use their radars to detect and foil the opponents. The most common game in Btooom! is Battle Royale.

BIM are distributed randomly at the beginning. If you kill an opponent, you get his BIM. Knowing all kinds of BIM is vital, as it is very important how a players uses them.

The game has multiple maps, such as a construction site, city ruins and a still populated city.[1] Smart players use their surroundings and BIM to trap their opponents and then kill them.

    Male, type 1: The most common and most seen type. This is the form that Sakamoto prefers when playing. The dark display with the player's number is on the character's forehead. A part of the face can be seen and the dark shades only cover the eyes.
  • Male, type 2: Another type of character. This type of player has a round helmet, with a large screen. The display is at the back of its head. A known player who uses this kind of suit is Kōsuke Kira.
  • Female: The female character is very personalized. It looks like a robotic version of the character the gamer wants it to be. It doesn't have any pupils and the face and hair are choseable. Himiko appears in Btooom! as a female character.
