In the spirit of the previous three games, we wanted to keep the character selection, the simple controls and the focus on a climactic face off with a well known villain, so we looked for a storyline involving the mountain that could serve as the right narrative backdrop.
We simultaneously started thinking about a new gameplay mechanic that would be just as simple for players to get to grips with as before, but that really pushes the level of excitement and challenge for players, with fast paced interaction and a rising sense of peril!
