MP5

Overview
The MP5 is the newest of the SMGs introduced into the arsenals of both the Combine and Resistance. It appears to be a standard MP5 modified with an underslung grenade launcher and suppressor.

The MP5 appears to be a rather unusual hybrid of the three basic SMGs, sporting the fire rate of the MP40, the accuracy of the Grease Gun, and the grenade launcher and stability of the MP7. For this reason, it can arguably be considered the best performing SMG in the base game.

Acquisition
The MP5 is the newest SMG added in the arsenals of the Resistance and Combine. As a result, it's much less common than the other three non-unique SMGs. It first appears in Highway 17, being held by a Metrocop behind a roadblock on a broken up bridge.

Afterwards, it will rarely appear in the hands of Soldiers, Metrocops, and Rebels.

Advantages
-High fire rate.

-Very stable.

-Relatively accurate.

-Decently high damage per shot.

-Moderate reload time of approximately 3.3 seconds.

-Underslung grenade launcher.

-Innate suppressor; shots will be quieter and NPCs may not notice you.

-Clear iron sights.

-Uses the very common SMG ammo.

Disadvantages
-Very rare when compared to other SMGs.

-SMG grenades are rare.

-Running will reduce accuracy, albeit to a lesser extent compared to other weapons.

Tactics
-As with the MP7, use the grenade launcher carefully due to the rarity of the grenades. It's best used in groups of enemies, or in last ditch situations.

-As the MP5 has a suppressor attached, you can take out enemies quietly before they even notice you. Headshots will give the best results.

-The MP5 actually doesn't perform too poorly at longer ranges, unlike the MP40 and MP7. Use this to your advantage.

-The MP5 has the fire rate of the MP40, allowing you to tackle groups of enemies better.

-Don't be shy to use the MP5 frequently. SMG ammo is almost always available, and will rarely be in short supply as a result.

-Keep in mind the MP5 only has an average magazine capacity of 30 rounds. Take care when firing, or you may find yourself running dry a lot.
