The following weapons can be seen in the video game Area-51:
M-11 "Scorpion" Pistol
The standard issue sidearm to Area 51 personnel. The weapon's overall size and shape best resembles a Desert Eagle. The gun has a built in flashlight along with a red-dot scope mounted on the slide. The magazine holds 8 rounds and each round is fairly powerful. Its name suggests the developers wanted to pass it off as a replacement for the Beretta M9; unfortunately, there already is a handgun with the designation M11, the SIG-Sauer P228.
XM-32 "Viper" Assault Rifle
The standard issue assault rifle for Area 51 personnel and Illuminati soldiers (as well as some alien mutants)). The weapon best resembles the Heckler & Koch HK53 compact assault rifle and, like the pistol, has a built in flashlight and scope. The gun can fire either in semi or full automatic, and has the ability to be dual-wielded. Accuracy is fairly decent on semi-automatic, but quickly decreases on full automatic, and is even worse when dual-wielded.
Frustratingly, the player is forced to dual wield whether they want to or not (similar to Crysis), although reloading will cause the player character to drop their off-handed rifle. The scope is not actually useable; aiming down the sights will just cause the picture to narrow, similar to older shooters like Battlefield: 1942.
M-170 "Hammer" Combat Shotgun
The standard issue shotgun for Area 51 personnel some alien mutants. The weapon best resembles a SPAS-12 and, like the "Viper", can also be dual wielded. The biggest change from the real SPAS-12 is that it has two barrels, two magazine tubes, and two ejection ports (one on each side of the receiver). The weapon holds 10 rounds (presumably 5 in each tube), and standard fire consists of one round at a time, while secondary fires two. Therefore, when using secondary fire while dual-wielding, the weapon will fire four shots at a time, causing immense damage. The gun also has a built-in flashlight, but no scope.
SR-125 "Wraith" Special Purpose Rifle
The main sniper rifle of the game, the weapon best resembles the PSG-1 sniper rifle. The weapon holds 6 rounds, and each round is extremely powerful. The scope magnifications of the weapon are 2x zoom and 10x zoom.
