The EGO powers

Hey guys, I was wondering: Is it possible to have multiple EGO powers at once? Because I noticed at the persuits that there was a challenge that you needed to max out all four powers. Can this be done without respeccing your points, or is this being achieved by maxing out one power, respec, choose other power, max out, etc?

I believe you can unlock all of them but you can only have 1 per load-out.

Yep one activated but multiple "attachments" ( forgot the term or word they used ).

What they said lol. you can have all 4 powers within your first 4 upgrade to your ego but can only use 1 power per loadout
