The next council mission you receive will be Confounding Light and will require you to activate 4 beacons and then proceed to activate the train’s main controls. The map is very similar to the other train station one encountered throughout the game. Again the enemies will be basic Sectoids and Thin Men, however this mission will have Mutons show up towards the end of the mission. Overall this is a relatively simple mission to anyone familiar with how the game is played.
NOTE: You aren’t required to bring Zhang along on this mission in order to unlock the achievement.
