Open game, Look at NDA,(now heres where most people get it wrong) Close the game, Youve backed them, your role is done, you don't need to play their game yet and torture yourself. Now wait three years and then come back, There will be a great game waiting for you, just leave a message for your future self..

In the future when they allow people to back the game again, Would dead matter still interest you, will there be no other games that fill the zombie survival games like DayZ did, well honestly I would be suprised if there was. If this game still interests you I would recommend looking at youtube, then considering if you have money to shell then consider a little bit more. If Dead Matter still looks promising and wasn't a scam the whole time, well then buy it. Just be weary that the game will still missing a lot.

Now that we're through with that, In the meantime you should look at a game called Project Zomboid, this is another incomplete project, But since this game can't be backed right now why not just hype yourself up with another zombie game while your waiting for the inevitable years Dead Matter will take, while thats happening you can play a difficult game and in a month or two, even die with your friends.
I needed this game with the current state of Dead Matter.
