Real Talk:
I never even played of Bungie's old Marathon trilogy, but I did hear a bit of it back in the day. However, with an announcement of a supposed revival, I looked up a Let's Play on Youtube and heard this line "Frog blast the vent core! from the infamous Bob clones.
Then this came about. Tsu seems just as confused as I am.
