It can be captured, contained in 2 slots same as triton, and dismantled for 50 mutagens like facehugger.
But it cannot be researched or vivisected, what is looking a bit strange - it is already on the base, why eggheads don’t cut it?

I suppose there is noting interesting to research. 
I cherished the hope that they can have psychic abilities

Same for the mist sentinel. Good for mutagens but little else.
I’m hoping that’ll be added for the main game.

I ve tried with ordinary ones. Waste of neural ammo, was later explained “rooted enemies cannot be captured”. Would be nice if some in-game warning could be issued Too bad they just dont add some interesting research, since all other aliens are capture-able.
