EARTH: Strikeforce: Morituri

A world under alien occupation in the near future, where an extraterrestrial force known as the Horde raids Earth for resources and slaves. Humanity's only effective response is the Morituri Process, a procedure that grants volunteers superhuman powers at the cost of their lives. The process is fatal within a year. The Morituri find items within the Horde's treasure ships that indicate they have visited the Marvel universe.
