As is clear to anyone, the main criticism this game faces is this: It has nothing in common with the core series it is a reboot of, with small exception.
My suggestion is this.
Rename it 'XenoShock'.
In an instant, everyone who said "I'm not going to buy it because it's X-Com in name only" become potential customers. In addition, the game receives the brand power of a highly successful game in the first-person genre, Bioshock.
Which would you rather play?;
X-Com in first person, with less aliens and no threat of dead squaddies
or Bioshock with squad tactics and research
