An alternate helmet is a piece of gear that provides both cosmetic changes and a small trade in two stats - for example, a decrease in health for an increase in shields. So far, every non-Prime Warframe, save Nova and Nekros, have two alternative helmets; Prime Warframes use the same alternative helmets as their normal counterparts.
Season 2 helmets introduced the use of jiggle-bones (dubbed by Digital Extremes as "Dangly Bits") which allow for a more natural secondary movement to the Warframe.
With the introduction of Nekros in Update 10, upcoming alternate helmets do not affect the stats of your warframes.
Helmets can be bought for 75 in the 'Equipment' section of the Market. Additionally, their blueprints can be acquired via completing Alerts missions.
Alternate helmets can be equipped in Arsenal, while a frame is chosen, the lower choice of those three tabs is "Appearance". They can be unequipped by reapplying the default skin.
List of alternate helmetsEdit
Most stat decreases take place after the effects of mods and auras have been calculated; however, increases are calculated independently from alternate helmets. As such, stat increases are always directly dependent on base amounts, and are always the same amount regardless of mods or artifacts.
For example, Frost's Aurora helmet reduces maximum health by 5%. Without any Vitality, a rank 30 Frost's health becomes (300 - [300 * 0.05] = 285). With a maximum rank Vitality(+440% health), their base health becomes (300 + [100 * 4.4] = 740), and their total health after Aurora's effect becomes (740 - [740 * 0.05] = 703). However, because stat increases are independent, it will always provide exactly 50 armor whether or not the Frost has Steel Fiber equipped.
