The ASMD Shock Rifle has changed little since its incorporation into the Tournament. The ASMD sports two firing modes capable of acting in concert to neutralize opponents in a devastating shockwave. This combination attack is achieved when the weapon operator utilizes the secondary fire mode to deliver a charge of seeded plasma to the target. Once the slow-moving plasma charge is within range of the target, the weapon operator may fire the photon beam into the plasma core, releasing the explosive energy of the anti-photons contained within the plasma's EM field. -- Official description

The Shock Rifle made it’s debut in the original Unreal Tournament, and it’s as useful as it ever was.

The primary firing mode shoots out a deadly blaze of plasma that hits instantly. The recharge rate is very good, allowing you to fire again two seconds after firing the first shot. It is a great weapon in any situation. The only time the weapon becomes a bad choice is if your target is jumping and strafing and moving erratically. Aside from attacking enemies, the primary mode is a great way of damaging nodes and cores in Onslaught mode.

The secondary firing mode launches a large plasma ball, which moves very slowly. It causes more damage, but is best used against stationary targets.

You can also use a third firing mode, which combines both types. Use the secondary fire mode to get the plasma ball going, then fire the primary attack into the plasma ball. When the beam reaches the ball, it explodes, causing tremendous damage. If you manage to get an enemy who has full health, he will die. If the enemy is fully armored, he can say goodbye to all of it, as well as half his health. It isn’t easy to pull off, especially in the middle of a big fight, but the result is certainly worth it.
