Marvel United: Secret Invasion Review: Skrull and Crossbones

About Marvel United: Secret Invasion, from BoardGameGeek:

The shape shifting Skrulls always had eyes on Earth. Their previous conquest attempts failed, but now they hatched a more insidious plan: a Secret Invasion. Skrulls disguised as super heroes implanted themselves into almost every team. Nick Fury Sr. and his trusty S.H.I.E.L.D. team have their work cut out for them to sort out friend from foe and foil the plans of the Skrull queen. Who can you trust? This expansion brings the insidious conflict between the Skrull invaders and the forces of S.H.I.E.L.D., aided by what Heroes Nick Fury can still trust. Face Veranke, the Skrull Queen, or take on a whole squadron of shape shifting Skrull Soldiers. To help them in their struggle, Heroes can go to Camp Hammond, where they can receive Advanced Training that just might give them the edge they need to stop the invasion.
