What the developers have to say:

Why Early Access? “With Early Access we are able to discover how to best mold the game for the community. It's a goofy game and we want it to be fun for the player. By placing it into Early Access before release, we can gauge which features are best to add or remove and find gameplay issues on a larger scale. We would like to use any feedback during the duration of Early Access to improve the quality of the game as much as we can. There are a lot of features that will be added over the next couple months and we are hoping that by using Early Access these features will be seen and used by the community so that we can see if they work correctly and find out if they are necessary or if the players feel they don't add to the game. Early Access is a great program for discovering what is broken and what is needed to bring you the best game possible.” Approximately how long will this game be in Early Access? “This game will most likely only be in Early Access a few months.” How is the full version planned to differ from the Early Access version? “The full version of the game will include unlimited horde mode, a short story mode, many characters and weapons, and a collection of rewards and achievements available. We are also looking into creating a multiplayer mode as well as a level where the player raids the base instead of defending it.” What is the current state of the Early Access version? “Currently there is one playable level with four characters, one vehicle, one weapon and few variations.” Will the game be priced differently during and after Early Access? “We do not have plans to raise the price upon release.” How are you planning on involving the Community in your development process? “We will be monitoring the Steam discussion boards and comments applied to our blog. Any comments about the game will be taken down and looked at as possible additions, and we will attempt to solve any issues found.”
