Everyone agrees, that a Die Hard video game would be incomplete without a Beretta 92F pistol. This is McClane's starting weapon, and is also used by Hans (instead of the H&K P7 seen in the film). The Beretta uses 17-round flush fit magazines. When switching to the 92F, McClane pulls the slide. When switching away from the Beretta, McClane will de-cock the hammer before holstering it. Secondary fire is the melee attack.
Heckler & Koch MP5N
The H&K MP5N is the main automatic weapon used by the terrorists. The game features a real MP5, unlike the film where chopped HK94's were standing in for the MP5.
Colt Model 733
The Colt Model 733 is mainly seen in the hands of SWAT officers and some bad guys. It is fitted with an A1E1 upper receiver and M16-style fixed stock. Utilizes 20-rounder, angled magazines (although, on the HUD it is shown with a 30-rounder mag). Shares ammo with the AUG.
Steyr AUG A1
The Steyr AUG A1 is powerful and accurate, significantly better than the MP5N. The secondary fire toggles the scope. When using the scope, the gun becomes semi-auto only.
M60E3
An M60E3 is used by Fritz, and later by a terrorist raining down hell on the police in front of the Nakatomi building.
Flashbang
Flashbang grenade of unknown make, used by terrorists very often.
Custom Rocket Launcher
The custom rocket launcher seen in the film is also present in the game. The terrorist uses it to take out a SWAT APC. In the movie, the launcher is fired twice, but only once in the game.
