Licensing various properties for video games can be expensive and it seems Sony wants to save a bit on their licensing costs as the Marvel costumes for Little Big Planet 3 will be removed from the store on December 31. However, you will be able to access what you've bought passed that date and so they're running a promotion where you can pick up the Marvel Mega Pack at a discount (£4.99) during the last few days the content is available for purchase.
