The primary submachine gun featured in Half-Life 2 is known simply as the Submachine Gun (SMG), with its design heavily inspired by the real-world Heckler & Koch MP7.
The Half-Life 2 Submachine Gun
The Submachine Gun is one of the most common and versatile firearms available to protagonist Gordon Freeman in Half-Life 2. It serves as a staple weapon for both the player and the hostile Combine soldiers, particularly the Combine Overwatch soldiers. Its distinctive appearance, while clearly inspired by the MP7, features a more futuristic and blocky aesthetic in line with the game's art style. Internally and by much of the community, this weapon is often referred to by its file name, weapon_smg1.
Design and Features
The Half-Life 2 SMG is a rapid-fire weapon ideal for close to medium-range engagements. Its main attributes include a high rate of fire and a respectable magazine capacity. A unique and highly effective secondary fire mode differentiates it from many other in-game weapons: it can launch 40mm fragmentation grenades, making it versatile for clearing out groups of enemies or dislodging opponents from cover.

Developmental Roots and Early Prototypes
The Submachine Gun in Half-Life 2 underwent significant revisions during its development, showcasing different design philosophies before settling on its final iteration. Early versions of the game actually featured two distinct submachine guns:
- Early SMG1: This prototype weapon was based on the real-world Heckler & Koch MP5K, a compact variant of the iconic MP5 series.
- Early SMG2: Also heavily inspired by the real-world Heckler & Koch MP7, this early iteration was, according to development notes, "somewhat more closely based on the real gun than the final SMG is." This suggests the final in-game SMG, while retaining the MP7's essence, adopted a more stylized and less direct translation of the real firearm.
Ultimately, Valve consolidated these concepts into a single, versatile SMG for the final release. The MP5K-based SMG1 was cut, and the MP7-inspired SMG2 evolved into the Submachine Gun we see in the game today, blending its real-world inspiration with the game's distinct design language.
Gameplay Role and Effectiveness
The SMG is a crucial weapon throughout Gordon Freeman's journey. It's often one of the first automatic weapons players acquire and remains relevant due to its combination of rapid fire and the powerful secondary grenade launcher. Combine soldiers also frequently wield this weapon, making it a common sight on the battlefield. Its effectiveness against various enemy types, from individual Combine soldiers to swarms of Headcrabs, solidifies its position as a go-to choice for players.
