No matter when Kickstarter campaigns run, or for how long they run, there's always a chance that you can't join in on it. Thankfully, there's the Late Pledge time where you can get in. It's basically a 2nd chance to get involved with the campaign and still get the exclusives and bonuses. For those that might've missed out on the Massive Darkness Kickstarter campaign, Late Pledges are being taken now.
The late pledge backers will still get the same stretch goals as the regular backers. You can see the image of what all you get above there. Lotsa stuff, indeed. The only thing is you'll get your stuff at the end of the shipping dates. But hey, still get the great Kickstarter deals.
