we are a spiritual successor to 'Fortress' and have taken alot of inspiration from 'Kingdom Rush'. currently lookin at a F2P model. however we are gamers first and despise 'pay to win' so we will be doin our best to avoid that.
challenge/endless are all free, mykeep is free and like kingdom rush, drives our marketplace. (which will consist of alternate playable hero characters, and tons of cosmetics for customization)
storyMode will most likely be delayed so we can put more focus into it to make it more robust and extend the content of each story act. were considering doin it like TellTaleGames does thier episodic games, buy each act/episode separate or all together for a discounted 'season pass' cost. with the first act/episode being free and each following act to be released about a month after each previous. as long as the game stays successful, we will continue to provide new content, stories, challenges. as well as cultivate the community for new player made challenges, we love modders!
