Where to farm
The mission selector for any map whose Campaign mission you have completed.
Survival is a map-specific mode that extends play through successive waves after you clear that map in Campaign. It gives you a longer opportunity to gather drops, but also asks your defenses to hold for longer. Unlock maps individually, then choose a comfortable difficulty and stop when the next wave threatens a long, productive run.
