The Mag-Rail is a fictional handheld electromagnetic projectile launcher which appears in Electronic Arts' 2004 James Bond spin-off video game GoldenEye: Rogue Agent. The by-product of space weapon research, the Mag-Rail uses a superconductive magnetic field to launch a depleted uranium rail which can penetrate walls, obstacles and enemy personnel. A powerful weapon that can kill enemies with one-shot, the Mag-Rail's primary drawback is a slow rate of fire. In addition, the priming time prior to each shot makes it difficult to hit moving targets. The weapon has a clip size of 4 rounds (5 in multiplayer) and the player can carry up to a maximum of 16 rounds in addition to the active clip (15 in multiplayer).
