The Blast Sensor consists of a spherical device, which generate a laser tripwire in one of the four cardinal directions. If the player touches the laser, the sensor will go off and activate any Blast Wires connected to it.
Blast Wires are connected to Blast Sensors. Once the sensor goes off, the wires will move at a predetermined speed and direction. If it connects with any Blast Crates when the wire burns, the crates will explode.
Blast Crates are explosive-filled boxes. They can be used alone, in which case they explode when coming in contact with fire weapons or other explosions. However, if they are connected to any Blast Wires, they will not explode until a lit wire reaches them. If multiple Blast Crates stand together, their explosion may trigger a chain reaction with nearby Blast Crates.
