From the OP: "After 4 years there were changes in the army and 80% of the teams were let go from the army and the team Damon was in was one of them. "
Game must take place in the 2020-2024 time frame, lol..
That aside, whoever mentioned that the family being 'dead' and a 'surprise' when he enters Witness Protection, yeah, saw that coming just from the game description.
Not a bad start, will wait to see how the story goes and we find out more of what happened, which 'bad guy' will show up again, etc.
