"Clear a dam facility overrun by those dam Zeds!"
Promo Page Description
"Water rushes around you, almost drowning out the creak and ache of machinery fallen into disrepair. Before you stands a giant concrete edifice, built to harness the power of a once mighty river. Will you and your team have what it takes to reclaim this facility? Welcome to Spillway."
- Both, map description and the achievement names make a pun of the word "damn" distorting and calling it "dam" since there is one in a map background.
