Contagion is a game produced by Monochrome Games that is the spiritual successor to Zombie Panic! Source, with several elements and references borrowed from the Resident Evil series, specifically Resident Evil Outbreak. The game was distributed via Steam and Desura on October 25th, 2013.
The following weapons appear in the video game Contagion:
The 9x19mm SIG Pro SP2340 has a capacity of 15 rounds and features a flashlight attachment.
M1911A1
The M1911A1 has a 7-round magazine and comes equipped with a flashlight and is modeled with adjustable night sights, nickel finish and wood grips. Somewhat curiously, the ammunition boxes are marked .357 Magnum. The game developers have indicated that this will likely change in a future update as it has caused confusion among players.
Revolver
An update released on December 12th, 2013 included a new weapon labeled simply the Revolver. The game developers indicated that it is similar to that found in Zombie Panic: Source. Its reloaded by two half-moon clips and does not feature a flashlight.
Shotguns
Mossberg 590
The Mossberg 590 appears as one of the games shotguns. Fitted with ghost-ring sights with tritium inserts as well as a flashlight attachment, the "Mossberg590" as the game calls it is a perfect all rounder weapon.
Over-Under Shotgun
The over-under shotgun appears as the "Over & Under". While it doesn't have the higher firerate of the 870 or the Mossberg 590, it can fire both barrels very fast if the fire button is held down.
Remington 870
A rather heavily modified Remington 870 appears in the game as the "Remington 870". Said Remington is modified with a usable flashlight, reflex red dot sight, silver finish similar to a Mossberg 500 Mariner, and not one, but two side mounted saddle shell holders.

Rifles
AR-15 Carbine
The AR-15 Carbine is a rather generic M4A1-style carbine rifle fitted with a RIS handguard and a flip up rear sight as well as a usable flashlight. It fires in full auto, like the following AKS-74u and is loaded from 30-round Magpul PMAG.
