What We Left Behind
Celeste told me you're the one who helped her hound me about pitching in more. I'll say this once: I don't appreciate the meddling, and I have my own reasons for refusing. I do, however, appreciate the scrap. Since you're apparently good at tracking it down, I may have a task for you.

Map: Buried City
An urban ruin partially swallowed by shifting earth and time. Narrow streets, collapsed buildings, and underground passages create a maze-like combat environment. Visibility is limited and ambush opportunities are everywhere, both for Raiders and ARC forces.
Navigation is the biggest challenge here. Mark your entry points and keep track of elevation changes. Underground sections can loop back on themselves. ARC Rollers are common in the tighter corridors.
