Guess you didn't notice the Raiden part.
You mean Raiden stabbing himself? That was in like... the second official trailer which came out in 2006.
I'm back with the game, managed to play it for 30 minutes (skipped all the fucking cutscenes) but I've got to go to work soon. Quick opinion, the game is basically Metal Gears of War. There, I said it. The stealth and action are about as akin to MGS as GRAW is to the original Ghost Recon. Stealth is still "kinda" important but with the addition of over-the-shoulder (I.E. Resident Evil 4 controls + strafe) aiming and tons more aggressive guards, the game is mostly a run and gun action game with some sneaking involved to set up ambushes and stuff.
But honestly, it's not a bad thing. At least, not as far as I'm concerned. The controls are wonkier than GTA4's but to me, Metal Gear has had way too many fights to incorporate the lame control schemes it had in previous games. It's nice to actually be able to dive for cover and properly shoot enemies without going into first person view then immediately switching out.
Full scathing review later.
