Forces is the only title to completely lack any zombies, and even it is more of an extra. This was inverted in Doom Ship, which starts out having nothing to do with zombies, but then they get on the ship. While all of them actually do include zombies, in many cases the zombies take a back-seat to the Monster of the Week. Steve normally uses SFM for his other fan videos such as 'Scared Stupid.'
An Ass-Kicking Christmas: Origins takes place on Christmas.Forces ends with regular Sonic waking up, but then encountering Balena's past Parody Sues, waking up from that, and eventually finding Zombie-Sonic floating over his bed.The very end of the series reveals that it was actually all a bad dream had by regular old Sonic, animated in Source Filmmaker.
