Blast Processing follows the adventures and tribulations of a party of very special NPCs (Non Playable Characters), Greg, Neale, Steve and Leena. These NPCs have become sentient within the world of videogames, gaining free will and the ability to question and defy the Players and rules that define their world. On their travels the NPCs befriend, antagonise, and generally disrupt the Players as they go about their game playing lives, resulting in ridiculous and humorous scenarios and guiding the party down a grander, world changing path.
