A Familiar Road
Mission One’s Commentary:
All idols like zombies to some degree, but not quite to the degree that X-Locks likes zombies.
The mall in Willamette (misspelled here as “Williamette”, understandably an easy typo to make) is the setting of the first Dead Rising, a Comcap production about a zombie outbreak. In Japan, it was an X-Locks exclusive.
The Japanese-language comic has the word “DOOM” written out in English, and all caps, in the fourth panel.
