Rocket launcher



The rocket launcher is used to fire rockets, missiles that fly in a straight line and explode when they hit anything solid. A direct hit does 148-288 points of damage; thus the rocket launcher is approximately as powerful as the super shotgun, but equally effective at long range and with a more rapid rate of fire. When picked up, the launcher contains two rockets (four at the I'm Too Young To Die and Nightmare! skill levels).

The launcher first appears in a secret area of the level E1M3: Toxin Refinery and appears again in secret areas of the following three levels. It is finally found in a non-secret area on E1M7: Computer Station. It can be used for rocket jumping in some areas, for example to reach the secret exit of E3M6: Mt. Erebus.

When using the rocket launcher at close range or within a confined structure, great care must be taken to avoid the effects of blast damage (even a player with 200% health and armor can be killed by several such accidents). For this reason, using a rocket launcher around Lost Souls or Pain Elementals is hazardous. Novice players may also be caught off guard by the weapon's "auto-aiming" characteristic, which sometimes causes a rocket to be launched a few degrees away from center if the nearest monster is not directly in front of the player.

Data



 * 1) This table assumes that all calls to P_Random for damage, pain chance, impact animations, and backfire checks are consecutive. In real play, this is never the case: counterattacks and AI pathfinding must be handled, and of course the map may contain additional moving monsters and other randomized phenomena (such as flickering lights). It is also assumed that all projectiles are launched at nearly the same range, so that the various procedures call P_Random in the same sequence each time. Any resulting errors are probably toward the single-shot average, as they introduce noise into the correlation between the indices of "consecutive" calls.
 * 2) Assumes that all rockets actually strike the target.
 * 3) Assumes that direct hits are possible, which does not occur in any stock map.
