Where to get regular frost system.

[(XBOX)PsychoLudacris]

I have been running ceres exta for about 3 weeks now for about 6 hours a day. I still have not gotten it to drop. I have had bosses and all and still nothing. If anyone can help it would be appreciated.  Ty

The boss encounter on Exta Ceres is the correct place, its just that sometimes the bosses really don't want to give you the parts you need. The new Kela and Lephantis are known do doing this.

Frost is pretty easy to get to - you have to hit up War on Mars.
