Ok I played it, and it seems kind of fun. I didn't finish the demo cause my keyboard fucked up but I completed the first of three objectives on the map. I played on casual because I've never played MOH before and didn't want to die parachuting. Now that I know the controls I'll give it another go on normal.
Anywho, it feels a lot like other shooters set in the same time period, the whole pseudo immersion thing etc. I guess if you're into that for level intros and what not then its not bad. At the start of each level you pick 3 weapons, your primary (seemed to be 3 different SMGs) secondary (I didn't check the options but I have a rifle with a scope) and a hand gun. I found myself mostly switching between the rifle to take out guys at long range and the smg for when I did things like enter houses or go commando. Never used my hand gun. For the objective I completed there seemed to be a couple of different options as far as how I could go about things so that's pretty cool. Its not like a ton of emergent options, but maybe 2-3 options that you can take based on play style.
As you go along you get "experience" for your different weapons (show as outlines of the weapons that fill in blue) and when you reach a new level the game gives you bonuses. It was kind of annoying when I hit one because it played a sound effect and then put me in some short term bullet time shit so I could soak up my achievement I guess.
The health system seems to borrow a bit from Halo. You have four boxes for health, as long as you don't lose all the health in a box it will regenerate automatically after a few seconds. This lets you peek around corners, shoot at people and take maybe one or two hits without dieing, then you can drop down regenerate and do it over. I only saw like 2-3 health packs that had been placed on the path to the objective I went for, but enemies seem to drop them from time to time when you kill them.
I guess that's all for now, if you have questions feel free to ask.
Performance wise I got about 20FPS on my old ass work machine (P4 3.6ghz 1gb ram 6600GT 128). That's on 800x600 low everything except textures which I think are on medium.
