That's what I'm talking about! This game's the bong 8-P
There were 53594 people in the town in the original Dawn of the Dead before the zombie outbreak. Deadrising took it's inspiration from there and had 53594 people in Willamette before the outbreak, the achievement is therefore equivilent to killing all the towns citizens. Left4Dead then came back with 53595 zombie kills, and Deadrising 2 came back with 53596. But why is this number also seen in Rockband 3?
Not an easy question. Dead Rising made you kill 53,594 zombies for an achievement, and alot of video games I guess 'one upped' it and started the 53,595 cycle. There really is no relation, just coincidence.
