After the success story of MP5, Heckler & Koch continued to develop selective firing close quarter combat SMGs, one of the development outcome and the official successor to MP5 is the UMP (Universale Maschinenpistole) series. UMP series of selective fire, recoil operated SMG that fires from a closed bolt, featuring three main variants which are designed to fire 9x19mm Parabellum, .45 ACP and .40 S&W. Compared to the older MP5 model, UMP was advertised to be lighter, more reliable, more modern and lower cost, other common features of the UMP SMGs are Picatinny rails placements and a foldable buttstock. Unlike the other to UMPs, UMP40 is more commonly found enlisted to service with law enforcement units rather than military service.
UMP40 is the variant that chamber the .40 S&W cartridge, like the other two variants, UMP40 also features a 2-round burst fire mode, together with semi-automatic and fully automatic, is able to reach a rate of fire of 650 rounds per minute, reaching muzzle velocity of 320m/s, covering up to 100 metres of effective range. Noted that UMP have their rate of fire reduced in order to compensate for the recoil generated from firing large pistol cartridge, making UMP series one of the slowest firing SMGs on the market. UMP40 weights only 2.3kg when unloaded thanks to the polymer made body frame, having a total length of 450mm with the stock folded (690mm unfolded) and the detachable straight magazine is able to hold up to 30 rounds of .40 S&W cartridge.
After some FBI agent casualties during the 1986 Miami shoot out, the bureau was on the look out for a better alternative munition type than the servicing 9mm Parabellum, ideally of a bigger calibre but with a manageable level of recoil. .40 S&W was the chosen in the end and gained favour with the bureau. Because of the adaptation into the service in the bureau, it gained popularity, many other special policing units and investigative agencies all over the world are adopting .40 S&W cartridge firearms into service, mostly in regions such as Australia, Canada and the United States, sequentially boosted UMP40's sale.
Character Design
SMG UMP45UMP45UMP45 and SMG UMP9UMP9UMP9's index number are 101 and 103 respectively, which before UMP40's release many player would have guessed the 102 index number will be UMP40, UMP40 joined the game at last with the event Operation Deep Dive. Though if one followed Renatsu.Z's twitter they may have noticed some posted artwork resemble a different looking T-doll with a UMP SMG long before her release, such as this twitter post here.
.40 S&W Cartridge is mostly used by law enforcement since it was more suitable with it's potential energy advantage over 9mm Parabellum and a more manageable recoil than the 10mm Auto cartridge of Bren Ten. Many character design features on UMP40 resembles that of a law enforcement unit or investigative field agent, such as the radio handset, smart business dress and the name card.
UMP40 was officially announced right before Deep Dive in July of 2017, she came fitted with voice lines, which suggests that her as a T-doll was programmed but never introduced into the game, or maybe never had an opportunity to be introduced. UMP40 chibi sprite retains a "Grenade Throwing" animation, which could potentially mean that her original skill was intended to be a grenadier unit before changing to the current skill.
Character Personality
The official character setting would say that UMP40 is a T-doll with super sunny and cheery personality, feels more superior than the others because of her UMP heritage, but she does possess a strong will and strong sense of team spirit. Most all of her silly actions and speeches are purely for the purpose of gaining attention of others.
As evident from her secretary and logistic mission quotes, her hobby is sunbathing, which would explains why she appears more tan than the other dolls. Other than sunbathing she also seem to enjoy partying. With her cheery personality she is good at making friends with other T-dolls, perhaps the silly way she act is merely a way strengthen the relationship bonding between comrades.
UMP40's personality contracts significantly from UMP45, this suggests that they are not twin sisters like UMP45 and UMP9, but just as similar models dolls instead. Which would also suggest that UMP9 was made afterwards, produced with UMP45 as a template.
Gameplay Info
As a T-doll UMP40 seem to belong in a very specific niche since she does not fit with most ARSMG formations.
Being unable to provide provide buffs to ARs can be considered a major weakness in ARSMG formations. 500% increased crit rate might seem a lot but SMG units by default only have 5% crit rate, when increased by 500% it only adds up to 30%. 100% crit rate can be achieved by fitting suppressors on them, which takes up the accessory slot, meaning the SMGs can no longer mount optics, which lose out on accuracy.
Though UMP40's own damage stat increases to a relatively high value after 10 seconds, 150% constant damage increase after 10 seconds meaning she can contest the MVP title even against SMG SR-3MPSR-3MPSR-3MP in extended combat sessions, but at the cost of evasion rating being lowered, renders UMP40 just as vulnerable as SR-3MP. By leaving the skill inactive UMP40's evasion status also increases up to a maximum value of 50% constant, but her low HP pool does mean she is not as good as the other top tier SMG evasion tanks such as SMG RO635RO635RO635 and SMG MP7MP7MP7.
Story Involvement (Spoilers)
One of the core characters in Operation Deep Dive, she approached UMP45 who in a similar situation as her during the prologue to Butterfly Event, thus the two became close friends.
Being on the same boat as 45, 40 also have an electronic warfare chip equipped in place of a fire control chip, which means she was also an under performing T-doll when it comes to combat. 40 approached the moody 45 who just came out of the shooting range, the two being in similar situation quickly made friends with each other. 45 was a laughing stock of the other T-dolls because of her combat performance, 40 regularly cheers 45 up by saying "Things will be different one day.", lead to 45 idolizing 40 not only as a friend.
Soon enough 40 realised that the electronic warfare chips are used to attack the forces of the 6th National Security Agency electronically in the whole Butterfly Event. After synchronizing their Cloud Atlas 40 found out that they are both modeled off the same Atlas format, 40 is the "key" while 45 is the "spare", the task that 40 cannot complete 45 will be forced under control and forced to complete it. Unwilling to accept this fate, 40 hijacked and took over 45 commands, completed the task on her own and relinquished 45 from the cruel fate.
In the very end 40 realised that in attempt to wipe out the evidence, all of the active T-doll Cloud Atlas will be formatted remotely except 45's. By lying to 45, she forced 45 into a duel and lost intentionally, 40 asked 45 to kill her in the end because she wishes to be killed in combat instead of being formatted. In truth she wanted 45 to become strong, to live not as a puppet but as an independent being, with the pull of the trigger, the shackle that binds 45 to her fate perishes.
