M870 Strategy Quotes

Individual Performance[edit]


M870 Possesses the skill "Highway to Hell", a very strong defensive skill which functions very similar to the Force Shield that certain SMG's use, said Force shield is also the same force shield a certain faction of enemies use and this page will give commanders a better understanding of the Force Shields defensive properties.


In terms of Stats, M870 possess very solid Defensive stats, possessing a high Armour Stat, tying herself with other dolls like SG Saiga-12Thumb button.pngSaiga-12 , SG CAWSThumb button.pngCAWS  and SG DP-12Thumb button.pngDP-12  as well as possessing a reasonable DMG stat, she's able to deal solid damage for an SG, her HP stat places her amongst the highest but not THE actual highest HP SG. Overall a very strong Defensive SG capable of surviving prolonged battles.

Skill Performance[edit]

Due to the nature of her skill and the general role of Defensive SG's this section in particular will cover the base mechanics behind M870's shield and how it works.

Ever since Major Event Continuum Turbulence was first released on the CN servers, Force Shield based skills received a rework changing how they function, originally they negated all forms of incoming damage while the skill was active, following the rework, they technically do the same, however they instead reduce incoming damage done by percentage based on their current "Max Defence" Value.

M870 was introduced in said Major Event as a drop and also possess a Force Shield based skill however hers specifically mentions what her max defence value is for her skill and that her "Current" Defence value decays as the skill is active. Below is a table of how much incoming damage is REDUCED while her skill is active for each respective Skill level. If the section is left as 0%, it means the skill has gone on CD by that time.

Skill Level Defence 0 > 1s 1 > 2s 2 > 3s 3 > 4s 4 > 5s 5 > 6s
SL-10 1000 (500) 100% 90% 80% 70% 60% 50%
SL-9 950 (550) 95% 85% 75% 65% 55% 0%
SL-8 900 (500) 90% 80% 70% 60% 50% 0%
SL-7 850 (450) 85% 75% 65% 55% 45% 0%
SL-6 800 (400) 80% 70% 60% 50% 40% 0%
SL-5 750 (450) 75% 65% 55% 45% 0% 0%
SL-4 700 (400) 70% 60% 50% 40% 0% 0%
SL-3 650 (350) 65% 55% 45% 35% 0% 0%
SL-2 600 (300) 60% 50% 40% 30% 0% 0%
SL-1 550 (250) 55% 45% 35% 25% 0% 0%

As you can see, M870's Force Shield gradually loses strength so she'll end up taking more damage as her shield decays. Another thing to note is while her skill does have a "Current" Defence value, it also does have a "Max" Defence value which is a fixed 1000. This is where the percentages are determined. On SL-9, her Current Defence is 950 which is 95% of her Max Defence Value, so all incoming damage will be reduced by 95%. On SL-10 however, for the first second of her skill's duration, she'll reduce all incoming damage by 100% meaning she'll completely ignore all forms of damage for that first second. This is also why SMG dolls like SMG ThompsonThumb button.pngThompson , SMG G36CThumb button.pngG36C  and SMG MP5Thumb button.pngMP5  are completely immune to all forms of damage while their skills are active, because their force shields have both their Current and Max Defence Values at 9999.

Now this doesn't make her completely immune to damage. Force Shields can still be damaged by enemies possessing 2 particular stats, a "Lethality" stat and "Piercing" stat. These stats may be familiar as our HOC units also posses these stats. Now almost all enemy units in the game dont possess these particular stats, however there are some that do so be mindful of this. Enemies which posses skills that bypass armour/EVA or can damage multiple dummy links, ARE AFFECTED BY THE DEFENCE VALUE! So damage done by these forms of attacks will be reduced, such examples can come from Cyclops's AP grenades which can be reduced down to doing 1 ~ 5 damage (Depending on M870's dummy links). However special installation units such the missile launchers on some maps (not Jaguar's or Jupiter Cannon's) have both a Lethality Stat and Piercing Stat, meaning they can damage M870 directly bypassing her shield which is VERY DANGEROUS!

Lastly, M870's Force shield can also stack with HP shields and other Damage reducing barriers. This is incredibly effective in further reducing incoming damage done to M870, as HP shields treat the shielded doll as a unit with 1x dummy links, so Grenade based damage will only do 1x damage, not 1x damage x target dummy links. So pairing her with HP shield giving units is an excellent idea.


Tile Bonus[edit]

Affects machine guns
Increases damage by 18%
Increases accuracy by 12%

Offensive Support:

Being an SG, M870's tiles will benefit all MG's by granting them additional DMG and ACC, however M870's tiles will only be able to buff 1 ~ 2 MG's depending on where she's placed on the frontline. Dont let this bother you too much though and be sure to make the most of it.


SG M870Thumb button.pngM870  is a Defensive oriented SG, meaning she'll benefit MGSG echelons which are aimed for prolonged battles. MG's that grant additional armour buffs via their tiles are a must have pair, such MG's include; MG NegevThumb button.pngNegev , MG MG4Thumb button.pngMG4 , ,MG Type 88Thumb button.pngType 88 , MG KordThumb button.pngKord , MG HK21Thumb button.pngHK21 , MG AmeliThumb button.pngAmeli  and a few others, Though with M870's base stats, one can consider pairing her with MG's that grant minor offensive stat buffs such as DMG, ROF and ACC.

Additionally, T-Doll's which grant HP shields are also exceptional pairs with M870 as they can stack with M870's Force Shield, greatly reducing incoming damage taken. Such shield using dolls can include; SG S.A.T.8Thumb button.pngS.A.T.8  (Highly recommend), MG LWMMGThumb button.pngLWMMG  MOD2 (Highly recommend), HG P22Thumb button.pngP22  (Highly recommend), HG HS2000Thumb button.pngHS2000 , AR MDRThumb button.pngMDR  and if you were present during the Valhalla collaboration event, then HG SeiThumb button.pngSei  is also an ideal pick.

M870 cannot tank by herself, so be mindful of who you pair her with, with M870's particular skill, she should be your primary tank and not your secondary tank so she should be receiving the brunt of Armour tiles. An ideal partner for M870 is SG FP-6Thumb button.pngFP-6  as she's able to apply damage reducing shields to 2 random dolls in the same column as her, these shields can also stack with M870s force shield further reducing incoming damage, her tiles as well can also compensate by buffing the MG who'll be on tile 1 while buffing the backline at the same time.


Slot 1

Type 3 Armor Plate

Standard equipment for Shotgun classed T-Dolls. Increases their base Armour at the cost of lowering their EVA, an absolute must for all SG's as it increases the SG's overall survivability, no reason to not equip them.
Slot 2

#000 Buckshot

Primary equipment of all Shotgun classed T-Dolls. Increase base DMG and Crit DMG, no reason to not equip them, all SG's should be equipped with them.


Primary equipment of all Shotgun classed T-Dolls. Multiplies base DMG by 3x and increases Accuracy by a moderate amount, however reduces the maximum targets hit down to 1 enemy only. An alternate option for SG's in the event you're dealing with singular high health enemies or bosses. Not necessarily required. As Slugs uses a different formula it conflicts with certain SG's skills rendering most of them less effective.
Slot 3

ITI Mars

Standard Sight for all classes except HG's. Increases ACC by a large amount at the cost of a minimal amount of ROF. For Defensive focused SG's, as you're not expecting them to be doing hard damage, its much more ideal having them at least hit their enemies then doing damage. Do not equip with Slugs, you dont need that much accuracy on an SG.

EOT 518

Standard Sight for all classes except HG's. Increases DMG and ACC by a moderate amount at the cost of ROF. For Offensive focused SG's, you'll primarily want them equipped with EOT's to maximise the effectiveness of their damaging skills. You may not be able to hit all enemies, in the event of high Scout presence, consider using a Red Dot Sight instead.

VFL 6-24x56

Standard Sight for all classes except HG's. Increases base Crit Rate by a large amount. For DPS oriented SG's or if you're expecting the echelon to be dealing with low EVA enemies, consider equipping your SG's with a Crit scope to maximise their overall damage. When dealing with singular enemies, consider pairing this with Slugs. Judge for example.


Standard Sight for all classes except RF's and MG's. Negates the night battle ACC penalty by a percentage, increasing the dolls chances of hitting an enemy during night sorties. If you're expecting enemies with EVA during night sorties, you may wanna consider equipping your SG's with PEQ's as your MG's may not have the ACC to handle said enemies. If only armoured units are present, you may neglect this and use other sights.
