I'm not sure why some are getting all offended that it's more sword play than gun shooting. It's Raiden we're playing now, & considering he's a cyborg ninja, guns are useless. Granted, this won't be your typical Metal Gear but why should it be if we're no longer playing as MGS2 Raiden/Solid Snake, but as a much more powerful being?
What I'm really excited about is Metal Gear 5, which might possibly be about the Boss & the Cobra Unit in the invasion of Normandy. Any chance to learn more about the Boss, I'll take it!
