Very unlikely combat will work in that way. More likely to be an interplay between what players currently have equipped and what they are doing.
Eg: “I’m going to climb on it and attack the weak spots, you shoot explosive arrows from a distance”
Either player could do one of those things, but one player alone can’t do both those things. Each player is still fulfilling a different strategic role.
We’re not really approaching Titans like an MMO raid boss equivalent, for what it’s worth. For example: assumption about the Titan having HP – Titans may not actually have discreet health points.
We’ve got some really cool, and I think quite original ideas, about how these encounters will happen. Hoping to share more at some point.
