What I saw from the MGS demo:
- The intro is the same as the one earlier in the year.... a good 5-10 minutes long
- You get a silenced pistol that seems to kill guys easily
- You get regenerating health
- You can see enemies through objects using some kind of infra-red mode
- Seems to be bullet time or slow mo mode
- Like most games out there, there's the typical chopper gunner scene to kill dumb enemies on the ground
- Good animations
- With all the clutter around, looks like you have good freedom to jump/hop over objects and climb stuff
- Either the wet shininess from the rain is awesome, or overexaggerated. Your call
- Snake's has terrible hair textures and movement
