The Heckler & Koch MP5, simply known as SMG, is a weapon featured in Half-Life and its expansions. The primary weapon used by the HECU, it is an automatic weapon with a high rate of fire. It is also equipped with what appears to be a M203 grenade launcher that boosts its effectiveness.

Overview

• The SMG's bullets will instantly hit a target as soon as the gun is fired. It uses the same ammunition as the 9mm Pistol.

• The attached grenade launcher fires powerful explosives that will automatically explode when hitting the ground. It does not need to be reloaded, so the player can fire as many grenades as they want until they run out of ammo for it.

• Both the MP5 and the 9mm Pistol use 9x19MM Parabellum and share the same ammunition reserve, making the MP5 and the 9mm Pistol very easy to find ammunition for.

• This weapon is first obtained at the start of the Half-Life chapter "We've Got Hostiles". It can be found next to a dead HECU soldier in the first room that has sentry guns. After that, it can be found in areas controlled by the HECU and picked up from dead HECU soldiers.

• When a player picks up an SMG for the first time, it will have 25 rounds in its magazine. The player must reload the gun to get 50 rounds in the magazine. However, in some related games such as Half-Life: Day One and Half-Life: Opposing Force, the MP5 already holds 50 rounds when picked up.

• When the Half-Life High Definition Pack is enabled, the MP5 becomes an M4 Carbine Assault Rifle.

Tactics

• The MP5's accuracy is suitable for short to medium combat ranges, but has poor accuracy at longer ranges, so it is recommended to use five round bursts for long range.

• The player should be sure not to use the MP5's bullets against large groups of enemies for the MP5's bullets do only 5 points of damage. Save the bullets and fire the MP5's grenades instead.

• Groups of weak enemies, such as Headcrabs or Houndeyes, can easily be killed with the SMG.

• The MP5 is effective on small groups of Vortigaunts and HECU Marines. With Vortigaunts, one should remember to move often to avoid being hit by the Vortigaunts electric bolts. With HECU soldiers, one should stay out of their effective range or make use of cover, since they have the same SMGs and slightly better accuracy.

• The Alien Controller is easy to kill with the SMG. Since its bullets hit instantly, the player can attack the Controller and avoid its plasma balls with ease.

• The SMG's accuracy is not affected by crouching.

Grenade launcher

• The grenade launcher should be used to clear out large groups of enemies at once. One grenade can kill up to five HECU soldiers with ease if it lands in the center of the group.

• The grenade launcher is also effective against enemies that have a lot of health, such as the Alien Grunt. One grenade can usually kill it in one shot. If not, it only takes a few shots from the SMG to finish it off.

• Using the grenade launcher against weak enemies, such as Headcrabs, is obviously effective but is a waste of ammunition. Melee attacks or normal bullets from any weapon are more advised.

• The grenade launcher is one of the few weapons that can damage a Gargantua, so one should stock up on its ammo when wanting to kill a Gargantua manually.

• If the grenade launcher is used at long range, intelligent enemies can usually run away from it before it explodes. Therefore, getting closer to the intended victims before firing is advised, as it prevents them from running away. However, being too close will affect the player's health, as with all explosive weapons.

Behind the scenes

• The MP5 was originally to be an M4 Carbine Assault Rifle. It was switched to the MP5 early in development, though the Half-Life High Definition Pack turned it back into an M4.

• The original MP5 had a different firing sound than the retail one. In addition, it could carry more than 10 grenades.

• The retail viewmodel and the early worldmodel is an MP5SD, while the retail worldmodel is a regular MP5.

• The grenade launcher in Deathmatch Classic uses a reskinned MP5 grenade model.

• Early textures for the MP5 can be found in the Half-Life SDK files.

• The MP5 originally had a 30-round magazine size.
