I've always wanted a game like this to be available on steam.
I know there may be other games like this, but for early access it's relatively bug free and fun.
I only have a couple issues with the game, and I'd just like to point them out here:
If you don't like doing the exact same "Hunt Zeds" objective after every location you explore, you might not want to play as of yet. It makes the game unnecessarily tedious and it makes me want to stop playing for a while.
Traveling back to base takes a long time (I'm not sure if it makes the game better or worse). To add to that, the same "Hunt Zeds" mini-game is necessary every time.
The game does feel a bit empty, but it's early access! It's expected.
But, don't let these minor issues I have with the game turn you away.
If you love RPG kind of games where you manage and command of up to four active characters and others waiting at base, this is a game for you! The way you upgrade your character both in arsenal and in ability reminds me of when I used to play with Lego mini-figures and gave them whatever new accessories in the unsorted bins. Sometimes it takes a while, but it's so satisfying giving your character new weapons and equipment.
And you can't sit idle and let your team do nothing either. Every day your survivors consume supplies, and if you run out, your characters die. That's it! They are permanently dead. That brings me to one last thing that I don't like. I think that the perma-death feature should be optional, but you wouldn't get as good of an ending or something like that.
All in all I give this game a 6.5 or a 7. The game does get boring and repetitive at times, but it's one of those games you can come back to a bit later and thoroughly enjoy again.
