Glock 18C

Is almost identical to the Glock 17. Unlike its real-life counterpart it does not fire fully automatic for balance purposes. It seems to have been modelled off the Tokyo Marui Airsoft line of Glock Pistols instead of the real Glock 18C. Its modelled with the safety on.

H&K USP

Note of interest: The texture is that of a .45, thus making it a .45.

Walther PPK/S

It is incorrectly shown to have a slide release when reloading and uses the same ammunition as the other pistols for gameplay reasons even though this gun is chambered for .380ACP round (9mm Kurz or Short). Lower magazine capacity than the other pistols but weighs slightly less than other pistols. In-game name is "PPK". Before the 1.5 update, the PPK was a weapon previously used as a punishable weapon should a player join the survivors just after a round has started.

"Winchester" Double Barreled Shotgun

A unknown make of double-barreled shotgun manufactured by Winchester. The longer barrels of the Shotgun allow a much tighter shot grouping allowing the shotgun to be used at medium range without much loss in damage. In early renders of the Shotgun it was previously known as the Winchester 1878 Hammerless. It is often nicknamed the "Fail Chester" because of the limited two shot capacity and the inability to kill more than one zombie.

HE/ Frag Grenade

HE Grenade shaped like an M18 Smoke Grenade. In-game name is "HE Grenade", but on the model itself the words "Frag Grenade" can be read. The weapon is NOT a Frag Grenade as it does not produce explosive shrapnel, instead it relies on direct explosive power with a 4.5 second fuse.
