Wow, this is the best video yet!
The Space Marines look cool. There's that shot at 1:35 showing them standing lined up in the dark looking ISOLATED. Ok, so they are a little bit stereotypical (bad guy called Lyle) but it seems there's going to be a bit of drama going on, making things interesting; it's not going to be as simplistic as Corruption where you meet the 3 bounty hunters in the beginning of the game then you fight them through the game as bosses. It looks like they work together as a team, and there's tension in the team... though Samus works alone.
The voice acting doesn't sound as terrible in the Japanese version. I wish they could release this with an option for Japanese voices and English subtitles.
Well, I'm looking forward to playing it.
