Lore: Developed in the early half of the 32nd century the objective of Bio-mimetic Armor and Internal structure was to provide less bulk then endo-steel and ferro-fibro's Armor while increasing the overall mobility of a unit equipped with it to make them swifter of foot while retaining good enough protection and durability. the result was a 10% increase in movement in both walking and running for a mech/battle armour or cruising and flanking for other unit types. While it also retained similar protection and durability as both ferro and endo-steel without being as bulky. but Bio-mimetic structure however only provides the same weight savings as endo-composite or a light fusion engine.
Gameplay Rules:
Bio-mimetic internal structure provides 75% of the total weight of standard internals, but takes up six critical slots. while also providing due to the internals mimicking biology provide a +1 MP to both walking and flanking.
Bio-mimetic armour is similar to standard armour in terms of protection, but for six critical slots provides +1 MP to both walking/cruising and running/flanking. When used in conjunction with Bio-mimetic structure, the total MP bonus is +2 instead of +1.
Construction Rules:
Bio-mimetic Armor provides 17 points of Armor per ton on mechs, Fighters and Vehicles and takes up six critical slots. this Armor provides +1 MP to both Cruising/walking and Flanking/Running MP. when used in addition to Bio-mimetic structure, this bonus stacks for a Total of +2 MP in both categories.
Bio-Mimetic Internal Structure Provides 75% of the weight of standard and provides +1 MP to both walking and running. This structure type takes up six critical slots. the MP bonus stacks with Bio-mimetic armour.
Costs pending.
Meta: Right so the idea basically boils down to armor and internal structure types that instead of providing better protection than standard types trade that damage reduction for increased mobility ton for ton. which is why when the two are used together they provide a flat +2 MP bonus to both walking and running on applicable units or +1 if the unit's only equipped with just one. Not as good as say MASC or a supercharger in that department but sometime some MP bonuses are better than none.
Edit: I also want to point out this not inner sphere nor is it Clan tech, but part of a WiP tech base and is meant to make up for the tech base's lack of MASC,TSM and superchargers. thus is not compatible with current mixed tech rules.
