So, you have a bunch of superheroes sitting around, all dressed up and nowhere to go, no villains to bash, so what do you do?
You could do a lot worse that pick up this neat little gem. Designed as a single 'scene' or one-off event that you can drop into your campaign or use for a single evening's play, it provides a passing supervillain who literally drops in on the 'heroes.... or at least causes an alien spaceship to make an unscheduled crash landing right under their noses. The race is on to save the city from further damage and thwart the villain's dastardly plot into the bargain!
The villain - who you may well wish to incorporate into your campaign as a recurring adversary - is called Dr. Count Von Vertigo - and he's provided with full stats and background and a nice full colour (or should that be 4-colour?) illustration. There are two other opponents provided as well, both capable of further development if you want to keep them around, and there's also a new superpower and some 'strange radiation' to play with in classic comic book style.
The 'scene' itself comes complete with an evocative read-aloud text to set the scene, description of the layout, several events and notes on what the other folk around are doing, and a few complications to throw in as and when you feel fit.
Grab your dice and your cape and have a blast!
