Rocket

The rocket is a brown missile the player may pick up to use as ammo for the rocket launcher. Normally a single rocket, it becomes two at the I'm Too Young To Die and Nightmare! skill levels.

A direct hit from a rocket inflicts a range of 20 to 160 hit points of damage (determined using Doom's pseudorandom number generator); the explosion may also cause additional blast damage. Rockets fired by cyberdemons do the same amount of damage as those from the player, blast damage included.
