Beautiful art here, with my two fave mass effect ladies looking good near Rio's well-drawn sunset. I like Firebase Rio; it's fun to fight in, looks great, and it's military and morale value seem pretty obvious: it's packing plenty of firepower, it's protecting the nearby city, South America provides three great options (The Amazon, The Andes, The Atacama) for a hidden human refuge for the Firebase to protect, and last/most importantly: the Interplanetary Combatatives Academy, I.e. the place where EVERY Human N7 was trained, is nearby. You know every Human (and likely Spec Op) N7 would fight like a devil to protect their old training ground.
