It’s similar in gameplay to Elder Sign as you visit locations and roll dice with different symbols on them to search for supplies / survivors / avert bad things from happening. Your “party” is always one group of dice that moves around the map together instead of 4 separate characters. There’s a doom clock sort of mechanism in that seasons slowly pass with each move your party makes, making crises more likely to appear and failing 5 crises in a row will end your game. Each survivor you find can be added to your party (max of 3, but your first character counts as two dice, all found survivors only count as one additional die). Failing to avert a crisis or combat with the mutated rats will injure your characters, and two injuries and they die. You can rest instead of searching a location to try and reduce your injury or starvation cards.
You have a headquarters that upgrades over time on it’s own, but can be expedited by sending items / food / survivors back to HQ instead of taking them for your party. Development cards also appear in higher frequency when you send stuff back to HQ and these can give you a huge boost when they finish “being built”. Survivors sent back to the HQ can fill empty slots in your party if you lose a couple people out exploring. Food and items however are consumed and you can’t get them back from HQ. I haven’t won yet, but I think getting your HQ to level 5 is one of the win conditions.
All in all I’m very satisfied with the purchase.
I’m also very happy that it’s a post apocalyptic survival game that doesn’t have anything to do with zombies.
