Possible making the game 1-3 for Co-Op , You and your friends run a camp with each of you being tasked with a certain assignment. You check the survivors coming in, one tasked with the “quarantine, Liquidation, Survivor block.” Each task can be set to multiple people or solo on one person.
New Station’s - Making your starter base able to “clean” the whole area and possible around it, Once you’ve “cleaned” that area allow a message to your computer to come in, Saying how they need help in another area for their station due to “lack of staffing”
I feel these ideas have potential behind them, Making the game bring in more people with the Co-op issue (some people don’t enjoy solo games, And enjoy playing more with friends) and the potential in helping “Clean” more areas (cities, states, countries even)
