Interplay has confirmed that Earthworm Jim, Dark Alliance, Descent and MDK are targets for future sequels.
Word comes by way of its financial 2007 results, which saw the sale of the Fallout IP account for USD 5.75 million of the total USD 5.86 income.
Interplay is also working on a Fallout MMOG as a licensee of the property, but is still trying to secure funding to make it.
This, along with its catalogue of old games, will apparently spell success.
"Going forward, we have the vision, unique intellectual property, and low debt and operational costs to help us pursue financing for our various projects," said Interplay boss Herve Caen.
"Our new website will streamline our ability to communicate development progress with the public, share brand information with the fans and support our customers."
There is still no change on the Interplay website, which had a place-holder image put up in early March to pave the way for the redesign.
