Okay, a few things there that scare me.
Third person view. I'm that's just to illustrate character movements, gestures and skins - they did the same with RvS - but I did let out an audible, "NOOOOOOOOOOOOOOO!"
Every round is a tracer. Am I the only one that noticed that every round fired looked like a laser beam? Won't be hard finding snipers in GR2. Just follow the beam of light back to his nest. One word...arcade.
Quake rockets. You know, the M136 that travels about 150 yd in 1 second. Just another feature that made me think of an arcade game. The other spot I found funky was about half way through when he uses a M136 to collapse a building on an enemy sniper position...standing in the middle of the road...taking fire...from 50yd away...broad daylight...etc etc. There's another thing that I hope remains a mere illustration of Havok.
The rest of the gameplay involving the tangoes can be pretty well ignored. I liked watching the player NPC soldiers just go running by enemies and neither would look or shoot at the other. The game is visually spectacular. The Havok physics engine will be an impressive addition to the style and feel of the gameplay. I just hope they take all that ghey arcade crap out and remember the features that made the PC port such a success.
Oh, and take out the 'Mid-level Boss'. That helicopter swinging around kind of just reminded me of Operation Wolf for some reason.
