For anybody thinking this new game will be anything like XCOM prepare for disappointment.
Jake has previously said that he is leaving turn-based tactics games behind.
And his tweet announcing Midsummer even says "it's going to seem very different from what I've done before."
edit: There is some good news for turn-based tactics fans. Another studio founded by former XCOM devs is focusing on turn-based games.
Once I was watching my brother play counter strike and he would turn away in game and irl whenever he threw a flash bang.
He didn't even realize he was doing this until I pointed it out.
