Gotta love how OP has no responses in this thread, even a single comment about their parenting choice to sit a 9yo down to watch a Warframe stream.
I've bisected many Corpus with my swords, decapitated many Grineer with guns and have committed various more war-crimes upon the enemies of the system.
You sure an M-rated game is appropriate watching material for your kid OP? Re-analyze yourself as a parent.
