Talk:Warframes/@comment-6540498-20140630005412

There are three factions, with three teirs of units (Light, Medium, Heavy)

There are 21 Warframes currently, and there are 7 Equip slots in the arsenal tab (Warframe, Primary, Secondary, Melee, Sentinal, Sentinal Weapon, and Specter Loadouts) 21 / 7 = 3

There are three planetoids (Ceres, Sedna, Eris) and 9 Planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto) on the Starchart. 9 / 3 = 3

Warframes require three parts to build them.

Each warframe has three non-ultamite abilities, and they all have three Helmets (Normal, and two craftable).

Oh my god...
