Blast Chamber was a video game created for the PlayStation and Sega Saturn. Arguably one of the first four-player playstation titles, the 'plot' of the game is "having a bomb strapped to your chest is fun".
In the single player game, the player navigates through 60 different cube-shaped puzzles, known as chambers. The player must collect a crystal orb and drop it off in the marked zone before time runs out or the player explodes and must start over. The game places heavy emphasis on the ability to kick the walls of the cube at certain points which causes the entire chamber to rotate, which is vital to that player reaching the end of each puzzle. Getting to the end of each puzzle gets progressively more difficult and more and more obstacles stand in your way. These range from platforms, to spike pits, to giant fans. Once the crystal is dropped off in the designated zone (the crystal chamber), the player then moves on to the next level. The only 'reward' the player obtains is after each level (a level consisting of a number of zones), is a small cut-scene where the player sees his character unstrapping his chest armor and tossing the C4 bomb away just before it explodes. Single player mode is always 'blue player'. On a second note, the four characters are never named, nor even given a gender as the body looks more or less androgynous though it's presumed they are all male.
This mode will have the player face off against up to three other computer or human controlled players in 1 of 20 different chambers. The goal is to stay alive the longest, and the winner is the last one alive at the end. Staying alive proves to be difficult, as each player has C4 strapped with a timer continuously counting down. Each player has a small pyramid holochamber assigned to them (one on each "side" of the chamber belonging to each of the players and color coded to match (red, yellow, green, blue) in which they can bring a crystal that is dropped at the beginning of the level to extend the amount of time on their timer (twenty seconds). The other players will try to grab the crystal from you though, by punching and kicking, and also by causing you to fall by rotating the chamber. Alternatively, a crystal can be dropped in a different players chamber to cut off time from their timer (twenty five seconds). Once an orb is dropped off into a chamber, another one will appear.
This mode is very similar to Eliminator Mode, except that there is a fixed amount of time that the game will go on for, in which the player who dies the least amount of times is the winner (or in the event of a tie, number of crystals in own chamber and number of crystals in enemy chambers will be compared for a winner - ties are not possible). Adding and losing time on your timer is the same as in Eliminator Mode, where the crystal is dropped off in different players squares.
