"These guys make up the bulk of the ADVENT forces we've dealt with. They're disciplined and well-equipped, but their obedience makes them predictable."
— Central upon discovering the first Trooper
"The ADVENT officers seem more capable than the grunts. We're not sure whether to chalk it up to training, or stricter mind control."
— Central upon discovering the first Officer
"At first, ADVENT deployed nonlethal stun units for crowd control and the occasional protest. We don't see a whole lot of that anymore though."
— Central upon discovering the first Stun Lancer
"Our resistance contacts heard rumors ADVENT might be rolling out a heavy infantry system. Looks pretty tough."

"No reason for them to hide, the aliens don't need an infiltration unit anymore."

— Central upon discovering the first Muton

"It is a remarkable species. If only we had some means of containment..."

— Central upon discovering the first Chryssalid
"This thing looks ready to smash something."
"Is that an environment suit? Maybe something that can't handle our atmosphere?"
"Those emissions could be toxic. I advise caution, Commander"
