Listen, 13 Sentinels: Aegis Rim looks absolutely gorgeous, but what does the game actually entail? Even after its most recent showing during Sony's TGS 2017 press conference, we still don't know what it's all about. It's got multiple playable high school students who pilot big mechs, but do we get to smash things up with them? Is this an action title like Vanillaware's previous efforts? So many questions.

Perhaps worryingly, there is a glimpse of potential gameplay in the trailer that we've embedded above, but it's not at all what we were expecting. Based purely on footage that lasts less than three seconds, it looks like some sort of real-time strategy bullet hell hybrid... thing. Hype deflated?

We'll need to see more, but until we get an actual gameplay trailer, let us know your thoughts in the comments section below.
