Taking a deep look into PROJECT universe.
I was very interested in this cool new universe Riot created so I tried coming up with possible theories made from hints Riot could have dropped. I explained it in a 25 min video if you guys are willing to watch it. It's my first video so the audio is a little weird, might have to turn the volume up.

but i'll still summarize my points here.
Basically all projects were manipulated (or maybe agreed to) into giving up their bodies to these scientists in order to achieve more power, or "limitless possibilities" as Ashe put it. The lies could have been different for each champion, but in the end they came up with something in order to get the champions to volunteer to be used. They used these champions specifically because they have extraordinary power that they want to use for their own purposes, which we don't truly know yet. Also they are seen tinkering around with their weapons, probably upgrading their current equipment. PROJECT Ashe is now trying to convince everyone to fight back against these scientists, and not let them abuse their bodies as weaponry. They are weapons to something that they don't want to be a part of destroying, this doesn't really include Zed because we don't really know whats up with him. Where they are in the current storyline is questionable, but Ashe says "time to go" and in the special interactions with Ekko she keeps saying he's going to help them escape out of something. I don't know where they are trapped, but clearly they need to escape something and Ashe needs the power of all PROJECTS in order to do it.
