The second will be Episode 6 - which will take place directly after the events of Episode 5, and will largely act as a set up to my next series set in Universe .08- Chronicle Bulletin. I don't want to say too much about the story, but I will say that it involves the aftermath of the virus on the city. There's also a little drama between the main 3 characters. The ending I currently have planned is prettttttyyyyyyy depressing, though I think it suits the series. :b
The Halloween Special will be much more light hearted. It takes place in one of Max's dreams during Episode 4. In it, naturally, Max is a superhuman with incredible strength and everyone thinks that he's really, really "coooo." This episode will basically be a big chain of zombie-killing microgames with stupid little bits of dialogue thrown in here and there.
These three episodes will all be up within the next 2 months. I get a lot of questions on newgrounds about new episodes, so I hope this answers some questions.
Toward the end of the year, I'm also planning to go through and update each episode one by one with improved microgames, touched up art and graphics, as well as a couple other bits and pieces. There are a few particularly not so great parts in the series I'll really be working hard to improve.
