Action: Source is a standalone Source Engine version of the 2002 Half-Life mod, Action Half-Life and is inspired by action movies like Die Hard and A Better Tomorrow. It is a part of the Action mod series by the same developers along with AQtion and Action-Quake 2. The game emphasizes "Movie Realism" by allowing players to dodge-roll, dolphin dive, and bunny-hop along with the ability to kick and bandage themselves up instantly, paired with deadly combat and fairly realistic weapons handling. The game features a rather realistic ammo system where remaining ammo in the magazine is lost during tactical reloads.
The following weapons appear in the video game Action: Source:
Handguns are the most common weapon in the game, and feature both "tactical" and "empty" reloads. Most handguns can be duel-wielded, an obvious reference to John Woo movies.
Beretta 92FS
The Beretta 92FS, called "Beretta", in game, is modeled after the two tone-variant of the Beretta 92FS. It incorrectly has a 3-round burst option and can be duel-wielded.
The Desert Eagle Mark XIX, just called "Deagle" in-game, is the only magazine-fed sidearm that can't use a suppressor. It features custom iron sights, and produces the distinctive "ring of fire" after every shot. It is also featured in the HUD icon for the "quick draw" equipment with a suppressor, despite not being able to use one in-game.
The Single Action Army is called the "colt saa" [sic], and is based on the "Cavalry" model. Its the only sidearm that can't equip attachments. After each shot, the Single Action Army is either cocked by the thumb or in a "fanning" action.
The Smith & Wesson Model 629 Competitor is just called "Magnum" and is the slowest firing sidearm. Despite using a speedloader and dropping unused rounds it does not discard ammo when relaoding.
The Mossberg 500 Cruiser is simply called the "Shotgun". It is based on a Mossberg 500 Cruiser modified with a foregrip and an removed heat-shield. It feeds from a six-shell tube magazine and has four separate pump-action animations. Its configuration is a clear reference to the Duke Nukem 3D "Shotgun".
A Generic 12 Gauge Double Barreled Shotgun appears in game as “Hand cannon” in reference to "Action Quake", like the Mossberg 500 cruiser in game it does not allow the use of attachments, it's primary fire shoots both barrels at the same time, whilst the secondary fire's one.
The MP5K appears in game simply as "Submachine gun", the MP5 is held in a side ways and or "Gangsta style" position, it can fire in full-auto or 3-round burst because of its "Navy" trigger group
The Colt Law Enforcement Carbine appears in game as just "Assault Rifle", it's incorrectly showed as having the ability to fire in full-auto and 3-round burst's, further more despite feeding from a 30-round stanag in game it only holds 24 rounds of 5.56x45mm.
The Accuracy International Arctic Warfare Suppressed appears in game simply as "Sniper Rifle" with a green tint, despite being based on the Integrally-suppressed variant of the "AWP" it can mount a suppressor, the scope is a overlay not a Actual scope, also despite the Suppressed variant uses 7.62x51 rounds it's only loaded with 6 rounds instead of the 10.
