Second Civil War
Somehow, the civil war breaks out again, only with different people on different sides.
One day, a pro registration team is sent to assault a base and obtain the blueprints to a device developed by Reed (who for some reason changed sides) that would shut down all of the weapons and electronic systems of the US military. The base is located in a large city, and was shielded by a cloaking device, until now. All citizens have been evacuated. Sue then took the blueprints, and in this fight she's trying as hard as she can to avoid being caught. Also, villians are in this as well for some reason, and many heros have joined or changed sides.
Attacking team:
Iron Man
Juggernaut
Magneto
Dr. Doom
Collosus
Wolverine
Storm
Cyclops
Defending Team:
Reed
Sue
Johnny
Ben
Dr. Strange
Spiderman
WW Hulk
Doctor Octupus
Hercules
Remember, this is in a large, New York size cities, no civilians.
Both sides get 1 day prep, but this prep must be used to plan tactics, or (for the team) to construct simple stuff, no making a giant gun that kills the other team.
