Upon starting the game, the player's only weapon is a fighting knife (appears to be the model Camillus made for the USMC Raiders), though almost immediately he obtains a Luger from a fallen guard. He can also use a kick simultaneously with any weapon, though the kick does minimal damage and is primarily useful for bashing open doors or inflicting property damage.

The third weapon the player finds is an MP-40 German SMG, which uses the same 9 mm ammunition as the Luger. Shortly thereafter, the player also obtains a scope-less Mauser rifle, which has high damage and accuracy, but uses different 7.92 x 57 mm ammunition. A scoped Mauser is obtained later on. On a technical note, the game's creators appear to have confused the similarly appearing semiautomatic M1 Garand for the Mauser rifle- all "scopeless Mausers" in the game are actually M1 Garands. The Garand was issued to US forces during WWII, not to the Germans.

In later levels the player receives a silenced Sten submachine gun, which uses the same ammunition as the MP-40 and Luger. He also receives a Thompson submachine gun and Colt .45 which are slightly more powerful than MP-40 and Luger, though with substantially rarer ammunition.

As the game progresses, the player also finds a flamethrower (though ammunition is somewhat rare), the Fallschirmjagergewehr Model 1942 (FG 42) paratrooper rifle (which uses the same ammunition as the Mauser), and two fictional weapons: a Tesla cannon and Venom Minigun. An experimental American silenced sniper rifle with infrared scope, called the Snooper Scope is also available, although its real-life equivalent did not have a silencer). All use unique ammunition.

The player also uses several varieties of explosives throughout the game, which include the Panzerfaust, dynamite and the "pineapple" and "potato masher" hand grenades of the Allies and Axis, respectively.

Several weapons have alternate modes of fire, which are activated by a key press. The Luger's alternate mode is a silencer (found on an early level), the Colt's alternate is dual-wielded Colts, and both the rifles' have an adjustable telescopic zoom as their alternate modes (neither scoped rifle has a visible crosshair in normal fire mode).

The Sten and Venom guns share a drawback: they overheat. The spread of bullets will increase as the Sten is fired (even though it is the most accurate of the SMGs), seen also as an enlarging aiming circle. While firing, a bar appears on screen which indicates the relative temperature of the weapon. Upon reaching a specific threshold, the weapon ceases firing until the bar has completely disappeared, indicating that the weapon has sufficiently cooled.

It is possible to pick up and drop chairs in the single-player portion of the game but only if the player has a single-handed weapon active, such as one pistol, a grenade or the knife.
