Shock Rifle

The Shock Rifle, also known as the ASMD in early games, is an energy-based weapon that fires either a hitscan bolt or a core (an "orb" of energy which travels across the map until it strikes a solid mass). In all of the games listed below you can shoot a bolt at a core to cause a "shock combo", a massive explosion which does considerable damage to anything within its blast radius.

Unreal
The ASMD fires a bolt or a Tazer Proj (orb projectile). The Tazer Proj in Unreal was very small, making it hard to hit with a bolt when moving, but this was rewarded by huge amount damage done by a combo - with Damage Amplifier enabled one could inflict 1200+ damage with one shock combo.

As revealed to the public by David Münnich, Cliff Bleszinski stated in a conversation with him that the name ASMD is derived from a movie phrase saying And Suck My Dick. This is so far thought to be the official explanation of the weapon's name. Some of the other, more funny and less provocative explanations of its name suggest it could also mean Anyone Seen My Dog, Automatic Spectrum Matching Device, Atomic Shock Mechanism Device and many others.

Unreal Tournament 2004
The Shock Rifle fires a bolt or a Shock Proj. It has a slightly slower orb than in UT2003 making it somewhat easier to create a combo.
