the advance to the siegnfried line campaign happens from sept. 44- some month in early 45 and would include such battles as bulge and market garden.
New Vehicles:
either the level 1 or level 2 unlock should be m18 for allies and hezter for DE and later down the line the jumbo, pershing, tiger 1, and tiger 2 as unlocks.
a premium plane could be the modified grasshopper plane called rosie the rocketeer that gets 6 bazookas, like actual bazookas, strapped to her wings and nothing else.
Unique Mechanic: field hospital
the requirements of this to spawn should be a 10-20% chance when america is defending in any mode outside of conquest. the rules for these are that both sides can enter and heal up but they can’t use weapons inside or within a certain distance, i’m think about 2-5 meters of it, and when they leave they’ll get a few second invincible timer or until they leave the no gun zone area to prevent camping it. to prevent people from abusing the invinc. timer they could set it so those rules can only happen if you aren’t at full health.
Unique mode: “encircled” name is subject to change
this mode should be the most common mode the bulge map. the attackers are able to spawn any outside of the fighting area, while defenders can spawn on the inside. the attackers need to either clear the area of hostile forces, I.E make the defenders reach 0 tickets, or capture all the zones. defenders on the other hand have to reach a maximum ticket amount with a steady flow of ticket income or reach the game’s time limit to win. balancing of this mode can be discussed.
the reason why i haven’t touched aircrafts or infantry equiment is because i don’t know what those should be so if you want to suggest those in the comments i would love to hear it
