Time Crisis IV
The following weapons appear in the video game Time Crisis IV:
Heavily Modified M1911 Variant
VSSE agents Giorgio Bruno and Evan Bernard use a heavily modified M1911 series pistol (visually similar to STI's M1911) with a weapon light. Like the previous game, Evan's handgun is two-tone, while Giorgio's is not.
Heckler & Koch Mark 23
Captain William Rush uses a Heckler & Koch Mark 23 with a weapon light mounted. This gun is loaded with 16 rounds in FPS mode. The Hamlin Battalion and Colorado National Guard forces also use it as their main sidearm, which is not correct since the Beretta M9 is supposed to be their main sidearm. In the PS3 version, the Mark 23 is also used by W.O.L.F. (Western Order Liberation Front) terrorists.
In the pre-rendered cutscenes, these Mark 23s are always fitted with weapon lights (because they reuse Capt. Rush's Mark 23), but in-game, Capt. Rush's Mark 23 is the only one to have a weapon light.
IMI Desert Eagle
Lieutenant Colonel Gregory Barrows, the commander of Hamlin Battalion, uses dual modified Desert Eagles with laser sights.
Mauser C96s are used by Wild Dog and his disciple Wild Fang to battle VSSE agents.
Heckler & Koch P7M13
Lieutenant Elizabeth Conway is seen with a Heckler & Koch P7M13 in the game's title screen.
Several enemies and Colorado National Guard use a very low detail SMG that doesn't resemble any particular real SMG. When they are killed, they drop G36C assault rifles instead.
Heckler & Koch G36C
A heavily modified Heckler & Koch G36C with a weapon light and stock removed is used by the protagonists, several enemies, and Colorado National Guard troops. It is referred to as "machine gun", even though this is an assault rifle. This gun holds 80 rounds in FPS mode.
A heavily modified Barrett M82 with a Heckler & Koch PSG-1 stock and custom foreend is used by Captain Marcus Black as his main weapon during the boss fight in downtown San Francisco. Despite the weapon weighing roughly 30 pounds and firing high-powered .50 caliber cartridges, Marcus not only shoots the weapon one-handed (much to the astonishment of Captain Rush), but manages to fire it accurately in bursts while standing and while swinging around using his grappling hook. His M82 also has a special feature in which he charges to fire a single shot that is guaranteed to hit the player he's aiming at, but leaves him vulnerable while doing so.
Mk 12 Special Purpose Rifle
An Mk 12 Special Purpose Rifle is used by the agents when they pursue a Hamlin Battalion truck but it only contains 2 bullets.
Mossberg 590 Compact Cruiser
A Mossberg 590 Compact Cruiser is used by the protagonists and fitted with iron sights and a weapon light. It's very effective at killing flying Terror Bites and pushing back heavily-armored machine gunners from using their knives on you at close range. It holds 8 rounds in FPS mode.
VSSE agents use commandeered M249-E1 SAWs from a Hamlin Battalion truck to engage Marcus Black in his boss fight.
Hamlin Battalion soldiers use a heavily modified M249 Paratrooper SAW with a Mk 46 Mod 0-style stock with mounted red dot scope and a weapon light. Lieutenant Jack Mothers also uses a modified M249 paratrooper, which has two guns clamped each together and a top mounted magazine feed.
FN GAU-21 Aircraft Machine Gun
A modified Browning M2 fitted with the muzzle brake of an MG42 is seen mounted on Hamlin Battalion and Colorado National Guard modified OH-58C Kiowas and modified Humvees. It also appear on Hamlin Battalion M51 Quad Anti-Aircraft vehicles and as a usable stationary weapon in FPS mode.
Wild Dog uses a Gatling Gun arm to replace the left arm he amputated after his defeat in the first game. It received upgrades, which includes a flamethrower and a rocket launcher (which were seen in Time Crisis 3). It also has grappling hooks and tractor beams.
Mk 19 Grenade Launcher
The helicopter in several stages has a heavily modified Mk 19 Grenade Launcher.
M79 Grenade Launcher
An M79 grenade launcher with pistol grip appears as a weapon icon in arcade mode. Its likeness is used for the icon of the grenade launcher.
Heckler & Koch HK69A1
A modified Heckler & Koch HK69A1 with double barrels appear only in the game's FPS mode.
The Pansarskott m/86, the Swedish Army version of the M136 AT4 with folding foregrip, is used by Hamlin Battalion soldiers as their main anti-armor weapon.
A (rather large) FIM-92 Stinger launcher is seen mounted on Hamlin Battalion modified Strykers and HEMTTs.
An M261 launcher with Hydra 70 rockets is seen mounted on Hamlin Battalion and Colorado National Guard modified OH-58C Kiowas.
Model 5210 Smoke Grenade
The Model 5210 Smoke Grenade is used by Hamlin Battalion soldiers in Arcade Story's prologue stage cutscenes.
Mk 2 hand grenade
The Mk 2 hand grenade is used by Captain Rush and Hamlin Battalion soldiers throughout the game.
M26 hand grenade
M26 grenades are carried by Hamlin Battalion soldiers in FPS mode. When they are killed, they drop Mk 2 hand grenades.
