Type: Miscellaneous, normal
Purpose: Boss Brain Explosion. Spawns RocketShot objects from the point (object.x - 196, object.y - 320, z) to the point (object.x + 320, object.y - 320, z), stepping 8 units along the x axis for each spawn, and using a random z coordinate of 128 + (rnd * 2). Each RocketShot object will be given a random z momentum of (512 * rnd), will be set to frame S_BRAINEXPLODE1 (#799), and will have its state's length modified by a random amount of 0 to 7 gametics, not allowing the frame length to be less than 1 tic. The object will then play the "bosdth" sound effect at full volume.
