Here's what I think, I played for about 2 hours last night:
The sound is top notch, I found myself smiling when I heard fire from around the map in Valhalla. Physics and flow of the game are solid but still some collision detection that could be scrubbed up (since it is a beta it probably will). Really like the lighting and texture style of the game it feels so much more heavy and real. I looks like they are in the process of including all of their finalized textures, because some areas are really textured and others are not, The leaves and tree textures will probably get much better as well as some of the other ground cover before the final release. (Just guessing)
I usually only play system link with buddies at my house so I really want a game that everyone and pick up and play, that looks polished and refined, I don't need gears, gears seems more dark almost too dark, I like these vibrant distinctions in colors in H3.
Overall I loved the game and can only think of how refined this game could become before release
One last thing did anyone notice that the sniper fire was not as responsive as you would like. I couldn't hit the broad side of a barn, by the time I got my second shot off the guy was gone? probably just me.
