Finally... after over two years of procrastination, it's out!
"Markie is in the pub at Retrovision, about to tuck into the pub's last mixed grill. When comic book supervillain Mixed Grill Man (aka Bane) realises that the pub has no more mixed grills left, he is distraught! In a fit of desperation he steals Markie's mixed grill, and makes a run for it!
You play the role of Markie and have to chase him and get your mixed grill back!"
