Bertil Hörberg, the creator of Gunman Clive, revealed Mechstermination Force for Switch not that long ago. The game is a collection of boss battles against giant mechs. In an interview with Dtoid, Hörberg shared his apprehension about releasing the game.
"I'm excited and terrified of the launch. We'll see what happens basically and I have to admit, it's not the perfect timing with Cuphead being announced. They're not the same game, but they are similar and being released so close together is not ideal."
It's true that boss battles are a key mechanic in both titles, and Cuphead certainly looms large above other games releasing on the Switch. That said, I think Mechstermination Force looks different enough to attract an audience. I know I'll be hopping on it as soon as it launches!
