Allied Corp upgrade question

[RedArgo]

Hello,

I've made it through the first three US scenerios in North Africa and I'm enjoying the game. Takes me back to the old versions of the game.

Anyway, I couldn't find this in the manual, but when upgrading units, why is the price sometimes the difference between the units like 300 to 310, so 10 points and sometimes it is the whole amount like 350 to 450 costing 450 to upgrade?

So, Wolverine to Hellcat is around 10 points or so to upgrade, but Warhawk to Thunderbolt is the whole 450.

Thanks.

I believe they go with whether the core 'frame' has to be upgraded. So a PzIVf to a PzIVg ..cheap. PzIV to PzV (Tiger) expensive. A moment of realism in Panzer Corps

what lparkh said.

same chassis, cheap

new chassis, full price, but you get to keep the exp and leader.

so plan ahead. Don't add new PKW III units if you know you want to be on the PKW IV product line later..
