We honestly need a female reveal.
"Exit the stage. Your act is over." - Vergil
"Come on, come on, come on, come on, come on! Now die!" - Albedo
I think ratchet is guaranteed, as for the other 2/3 I think they're Nariko, Snake, and maybe Sackboy
I would really like Isaac Clarke too but I don't think he's too likely
It's really hard to say, but Ratchet & Clank wouldn't be the most incorrect guess. I'd love to see another female fighter, either Kat or Nariko.
It'd be great to see a Chimera as a playable character. They're the most recognizable Resistance character, and way more interesting than another soldier.
