The MP5 has a very manageable recoil that allows the user to control it with ease. However, it has rather underwhelming damage output. Combined with the slightly below average fire rate of 800RPM, this makes the MP5 easily fall into the slightly weak category.
It is capable of taking out Light Armored Operators in four body shots of its effective range in a quarter of a second, while Medium and Heavy Armored Operators take five. Suppressed, the MP5 will be able to take down Light Armored Operators in five body shots, but the other two Armor Types will take six.
In the alpha versions of the game, the MP5 was called by its proper designation, the MP5 MLI.
In reality, it would be extremely awkward to perform a tactical reload on an MP5, due to the way the bolt was designed. The bolt rides directly on top of the feed lips of the magazine, blocking a full magazine's entry into the magazine well. This prevents a fully loaded magazine from properly being seated if the bolt is in battery. This is why it is recommended that the bolt is to be locked back during tactical reloads, or a partially full magazine to be inserted. Either way, a 30+1 capacity would be extremely difficult to achieve in real life.
The MP5 was previously available on operator Oryx, and was replaced with the more powerful T-5 SMG for balancing reasons.
From Operation Steel Wave to Operation Neon Dawn, the MP5 had a short-lived Angled Grip option available on Oryx and Melusi (as a weapon swap took place. Melusi originally had the T-5 SMG while Oryx had the MP5, they switched these weapons and Melusi ended up with the MP5 Angled Grip option. However, this only applied to Oryx's and Melusi's MP5, and was not available on Doc's nor Rook's MP5). As of Patch 5.4.3, the attachment is no longer available.
