Internals add helpful effects to mechs. They modify the play-style of particular mechs to customize them to the user's preference. These effects are permanent so long as the internal is equipped. There are six internal slots on each mech, with certain internals occupying different amounts of slots. Low level internals take up one or two slots, while high level internals use three slots. Internals are not universal and when purchased are only made available for the mech whose internals selection you were browsing. They can however be taken out then reequipped at a later time with no penalities.
Internals may be purchased with HC or MC. MC can also be used to buy internals before they are unlocked via ranking up one's pilot level.
Internals taking up 1 slot all cost 320 Hawken Credits or 36 Meteor credits.
Internals taking up 2 slots all cost 640 Hawken Credits or 72 Meteor Credits.
Internals taking up 3 slots all cost 960 Hawken Credits or 108 Meteor Credits.
When the Armor Fusor and Advanced Armor Fusor are actively regenerating health after a kill or assist, a new kill or assist will override the current one. This means getting a kill then an assist right afterwards will only result in a health regeneration worth an assist, and vice-versa.
If the regeneration was already ongoing, it will switch immediately to the regen rate for your latest kill/assist.
