The Advanced Sniper is a sniper rifle in The Ballad of Gay Tony.
Based on the DSR-1, it uses 10 rounds per magazine, and, like the Assault SMG, utilizes a bullpup configuration. The weapon is also available with explosive rounds, which are incredibly powerful enough to take down most targets with one shot in single player, but the rounds are only as effective as Frag-12 shells in multiplayer.
Its first encounter is during the mission Caught with your Pants Down, where the player must use it to free the APC for Yusuf. The weapon is also demonstrated by the "Terrorism Expert" during a pre-release Weazel News Report demonstrating weapons featured in The Ballad of Gay Tony.
