I've always had this dream of seeing a new uber version of.. wait for it... Alpenfestung TWO! made in objective mode.
With an underground secret weapons factory dominating the second section of the map, from which all the German toys are spawned, with their static parked/ uncompeted versions being objectives to destroy, and the final one being the closing of Metal Gear Solid, The Ratte defended by among other things, 2 Maus and at least one ME262, that requires the ever increasing arsenal of the allies as they cap flags, to destroy it.
The battle evolves from the chunky defenses of bunkers in open fields and AT guns, to low stony walls, and finally, the factory.
The setup will be such that the Ratte cant be destroyed head-on while its in the factory, but needs to brought out in the open (Both sides need this because the Germans will bleed fast until one of the former bases can be recapped, and the Yanks and British special forces need this to bomb it from the sky or hit it from the rear.
The factory fighting will be dark, with metal pillars, stairs, upstairs rooms and parked vehicles, the key ones like the King Tigers, Sturntigers and take-off bar for such things as the Nater and V1 etc etc that need to be destroyed.
You get German vampir pickup kits for infantry and scoped STG44s with such tech in that area, with the Allies firing mostly blind.
I also wish some maps in conquest will be objective in 64 size - Like Hyacinth, Battle of Britain etc. So that people know objective gameplay can work alongside.
