This game looks pretty awesome. It looks like it is the true sequel to Battlefield: !942, but with a larger focus on infantry combat. (there are tanks, but no jeeps, planes, or boats). 
 
RO2 seems to be making a lot of adjustments to the first person shooter, and it is looking like a very PC game. 
 
There is a cover button to stick to cover, you can blind fire, lean, peak up, etc. 
 
The sniping looks really cool, as there is a 3D scope, so instead of th whole screen zoom in with a scope overlay, the scope is actually 3D... it's hard to describe, but it looks really cool. 
 
It looks really awesome. Additionally, the team that is making this got started with mods, so they will be very open about that stuff, so we might see some modern combat mods once it releases.
