A sniper rifle is a high-precision weapon meant to take down targets at long ranges. These are usually equipped with scopes, and the class is divided into two other classes, the hunting rifles and the anti-materiel rifles. Sniper rifles have appeared in all games thus far.

Contract Killer

Sniper rifles first appeared in the first game in the series, Contract Killer. They are high precision weapons that shoot high-damage rounds, with low rates of fire.

List of snipers in game

• Timewarper Rifle - A sub-par weapon with a steep price for low levelled players, the Timewarper Rifle is a somewhat psyched up version of the standard Sniper Rifle with a deeper mag size.
• Sniper Rifle - A high-precision, three round, bolt action sniper rifle with a matte finish, this weapon has some sway but less than the Timewarper Rifle.
• The Defender (removed) - This odd-looking sniper rifle has better range and a much deeper mag than the Timewarper and Sniper Rifle, but inflicts less damage.
• High Balance Sniper Rifle - Arguably one of the best sniper rifles in the game, the High Balance Sniper Rifle combines accuracy with firepower to create a beast of a rifle.
• Accuracy Plus Sniper Rifle - An upgrade to the sniper rifle, this version of the popular weapon has a leaf camo finish and better accuracy.
• Ballistic Sniper Rifle - One of the more expensive weapons in game, this rifle combines superior damage with a big mag size.
• Cheetah Rifle - An upgrade over the Ballistic Sniper Rifle, this rifle boasts even better range, damage and firepower.

Contract Killer: Zombies

The second installment that the sniper rifles appeared in, the rifles now have better animations, and now the player actually cycles the bolt after firing.

• Hunting Rifle - Not to be confused with the Hunting Rifle in Contract Killer or the class itself, this rifle is a sub-par sniper rifle with a decent mag size.
• Commando Elite - An excellent sniper rifle, the Commando Elite can gib zombies easily and has a deep mag size.
• 30-06 Rontron - The second-best sniper rifle in game, the Rontron fires a powerful 30-06 round with every shot.

Contract Killer 2: Shadow Conspiracy

The third installment the class appears in, the rifles now get a full-body shot due to the game being shot in both first and third-person views. The rifles also have unrealistically low recoil.

• Bronson S86 - The first sniper rifle in the game, it comes with a virtually free ACOG sight, and is not very powerful.
• M390 ASR - The first gun used in the game, which is lost after the player gets wounded in game; it can be repurchased, and is a decent sniper rifle.
• Defender II - The successor to the original Defender, it sports a smaller mag with a better scope.

Contract Killer: Zombies 2: Origins

The fourth installment where the rifles appear in. The rifles are now seen entirely in third person; only their scope view is in first person.

• Commando Elite - The same weapon as featured in the prequel, the Elite has been immensely nerfed to make it the weakest sniper rifle in the game by far.
• 30-06 Rontron - The same weapon as in the prequel, the Rontron has been buffed to become more powerful than its original version.
• Auto Sniper - The only original sniper rifle in the game, the Auto Sniper is arguably the most powerful sniper rifle in the game, boasting the biggest mag size, and high damage.
