Besides the Alien easter egg when you encounter the one alien, does anyone know if there our other alien encounters or other alien enemies in the game? Maybe in the story or by doing side quests? Or even by free roaming? Haven't encountered any. Does the alien in the cave respawn after you have killed him and picked up the alien blaster? Thanks.

As far as I am aware, that is the only Alien in the game.

I explored every marked location , and did every sidequest, and say no other aliens, or alien tech. So, unless it was just REALLY well hidden, that one alien was it.

Cabot has Zetan weapons, beyond that though, nothing.
