Short Version: How much you want to waste on a bad game that is on its way to having its online functions shut down.

Long Version: The deluxe edition comes with the DLC that gives the first nine character packs in one DLC. The ultimate edition gives you everything the deluxe does plus some t-shirts and in-game items. I'm not sure if the t-shirts can be obtained in a different DLC or not, but even if they can't they probably aren't worth the price difference between the deluxe and ultimate editions.

How can you NOT see that it literally explained at the Main Page?

There's a YouTube video that shows you all the extra shirts you get with the ultimate version.

Is there not single way to purchase jumpforce in steam account in 2024??
