People love to think "what if" in regards to a lot of things, but to WWII, specifically. That includes many game designers. Konflikt '47 is one such result, giving us a war that continued on, as well as imbuing it with a lot of strange technological advances. There's three new releases for it over in the Warlord Games webshop.
All of these are things that look fairly familiar, but with a bit of a sci-fi twist. There's a new squad of US Heavy Infantry. There's also the M4A9-T Sherman Tank with Tesla Cannon. Last, but not least, you have the German Pz-IV-X, armed with a gravity cannon. All of it looks fairly similar to things from WWII, but with just that bit of extra tech.
