We managed to implement the first 5 scenarios for the Defcon 5 stage.
Some new additions:
We added a Blood sample mechanic inspired by the movie "The Thing"
How it works?
One of the civilians that you must rescue is infected and if you try to save him with a soldier or engineer he will transform into a monster and attack you but if you try to save him with a medic you will immediately identify the infected and you will not trigger him.
Another new mechanic is the infected stash devouring flesh.
They will ignore the player units while eating but if you attack any of them they will all rush toward your strike team.
Also, we added tons of easter eggs and fan service.
For example one of the early possible scenarios will be an easter egg from Resident Evil aka Kendo Gun Shop.
And much more, we added custom scenes during exploration such as helicopters passing by, civilians running and trying to escape, car crashes, and much, much more.
OK time to go back to work.
