Hey guys...I've been following WWII On-line for awhile now and I'll try to fill you in with some basics. Go to www.hq.ww2online.com for an updated FAQ on everything you want to know.
Rank is handled by you completing a successful mission. Say you just started WWII On-line in the German Army. You'll be a Private and only basic weaponry will be available to you. Missions are posted by people with higher rank and you can find one that you like. If you attain the rank of General, or any other high rank, you become more responsible for the strategic operations of the entire branch you are in(Army, Navy, etc). Depending on the mission type depends on the amount of points awarded. You don't have to accept rank, and there can be only a certain amount of 'active' high rank positions(Can't have 20 Generals in the Army all calling the shots).
A very realistic physics and strategical model is being developed. Fire a rifle and your bullets will be subjected to wind, bullet drop, etc. Run out of ammo, you need to be resupplied by somebody(Truck, plane, etc). Get in a hand-to-hand fight, shock and fatigue comes into play to where you may be too worn out to run away from your knife wielding attacker. Tanks can have treads thrown, turrents knocked out, etc.
Strategically, everyone won't be able to fly around in a Me-262. Only people with certain rank in that service branch will be able to fly quality planes(Same with any other branch...can't just start out with a Tiger or command a Submarine). And even then, there will be a limited amount, AND limited airfields, etc. from where they can take off.
Trust me...I'm not the only one who thinks this game is a daunting task, but just download some of the in-game videos so far and tell me you aren't impressed. Closed Beta has started and is still in Phase 2 I believe. Whoever signed up for Closed Beta has a chance of being in a certain phase. The last phase of the Closed Beta will probably be most if not all the people who applied for it. After that's completed, I believe Open Beta will start.
I can tell you this for sure: WWII On-line will not be even close to a Quake type game. The guys doing the development are very hardcore. They even plan on having visible hit-specific damage, such as bullet holes. I'm positive they can pull it off, but only beta will prove that.
