Vortex rifle

The Union Aerospace Tactical Division V-ORT.X Rifle, or vortex rifle, is a new energy weapon which appears in the multiplayer and SnapMap modes of the  Doom. Referred to in passing as a "laser sniper rifle," it can be focused to deliver more powerful shots at a longer range. The focusing process is done in the alternate fire mode, in which the wielder makes use of vortex rifle's optical scope to charge the weapon's shots. However, a distinctive laser sight is produced during the charging process that can reveal the user's location.

"A precision long-range energy weapon with a magnified optic."

Easter egg
When viewed in the multiplayer customization menu, the the butt-end of the weapon's stock can be seen to have some text written on it, as if with a permanent marker: "Capt K. Cloud PLT 46-849" This refers to long-time id Software artist and producer Kevin Cloud.
