AI Mechanics - Line of Sight and Tracking

[Stricknine]

Does the AI play by the same rules as the player when it comes to LoS and knowing the positions of units?

For example, if an alien sees one of my units, I assume that all aliens would know that unit's location and be able to act on that knowledge

But if an alien sees me during my turn and I move out of LoS, does the alien continue to track me outside of LoS, or does it use my last known location (and maybe even the direction it saw me go) to try to relocate me?

I ask this because in the original X-COM, certain aliens could track you outside of LoS for a number of turns, and I wasn't really a fan of this mechanic.

Not at the moment, no. Right now all aliens know exactly where all your soldiers are once they go into "combat mode" after sighting a hostile unit. We're looking to implement a fairer system in the next major update.
