Oneshot Rifle / Elephant Gun
The One Shot is a heavy-class Sniper rifle/Recoilless rifle. One round will vaporize your target into a red mist. It was a very effective weapon for fighting Drones and the Lambent. The rifle is so powerful that it can explode a Boomshield and stun what is on the other side. However, it is known to have a very long reload time and it has to charge for a few seconds (automatically while aiming) to compensate for this. It also makes a buzzing sound and has a red laser as well. (-Gears Of War Wikia)
