I'm working on getting to Gen 4 and this satchel charge/plasma railgun challenges are a pain. Any tips from anyone that finished them?
Go after damaged Titans and steal kills. Use instant shot. Use ordinance while reloading (unless the enemy titan's health is low and doing so would risk dooming it).
I started the challenge yesterday and have 9 more titan kills to go.
I still need to kill more minions/pilots to complete that challenge though.
The satchel charge kills were pretty annoying. Did a lot of jihading just to get the kill.
