Battlefield 1942 had a cool "secret weapons" expansion. I can see that working for company of heroes. also, not all of the weapons would necessarily be "secret", some could just be "experimental" units, like the American M6 tank.
Germans with Jetpacks would be some cool shiznit.
Are the Devs even going to listen to this topic, even though 'Yes' is at 48, its their final call.
