Crysis

SCAR

The weapon used by the Marines and the player is actually a Heckler & Koch XM8 chambered for 6.8x43mm; this implies that in Crysis' world, the XM8 won the SOCOM SCAR competition rather than the FN Mk.16 and Mk.17 as in real life. The assault rifle can be customised in-game; the player can attach either a reflex sight, assault scope or a sniper scope to the upper rail. The forearm side rail accepts a two-mode module that functions as either flashlight or laser sight. The underbarrel mount accepts a grenade launcher with a built-in rangefinding function that provides a reference point for aiming at a set target, or a bizarre device called the 'Tactical Attachment' that functions as a self-replenising, completely silent dartgun. Finally, a suppressor can be attached.

FY-71

The FY-71 is the main weapon for the North Korean soldiers in-game. It is actually based on the AK-74M, chambered for 5.45x39mm. Like the SCAR, it features the ability to be customised. It features all the same modification options as the SCAR, with a single addition; it can fire incendiary bullets as well as regular rounds.

MPX8

The MPX8 is the main weapon for North Korean forest patrols. It closely resembles an Heckler & Koch MP7A1 albeit somewhat longer and uses 4.6x30mm rounds. The MPX8 can also be seen in the hands of some North Korean nanosuit soldiers. The MPX8 has the same modification options as the SCAR, safe that it lacks an underbarrel mount point.

DSG-1

As the name implies, it's based on the DSR-1 with a forward mounted 10 round detachable box magazine and barrel that resembles that of the H&K PSG-1. It can be equipped with all scopes. The weapon is used by North Korean soldiers and North Korean nanosuit commandos. It presumably fires 7.62x51 rounds.

Bauer SOCOM

Judging from the 20 round magazine, it's most likely based on the (prototype) 4.6x30mm H&K UCP. It is wielded by North Koreans and US Marines. It can be dual wielded, set to a two-round burst firing mode, suppressed and / or equipped with a laser/flashlight combination.

Tactical Shotgun

The shotgun in Crysis is based on the Benelli M4 Super 90 but is operated by pump-action (more like the Benelli M3. It uses 12 gauge shells (fed from an 8-round integral tube magazine) and has an adjustable choke that can increase or decrease the spread. Unlike most video game shotguns the Crysis shotgun has fairly realistic accuracy. It can be equipped with all scopes and laser sights/flashlight.

Hurricane Minigun

A homage to Predator's hand-held M134 Minigun, the Hurricane Minigun can only be used by nanosuit soldiers (both the player and the North Korean commandos). It fires from a 500-round drum magazine and can be equipped with a laser sight (quite useful as the minigun doesn't have iron sights).

GK8 Gauss Rifle

Used by US Marines and the player. This futuristic electromagnetic rifle fires depleted uranium slugs at 8 times the speed of sound dealing massive damage on impact. Doubling as a sniper rifle and as an anti-vehicle weapon, it has a five round magazine and is very effective against the alien war machines. It can be equipped with all scopes.
