These include franchises such as Darksiders, Red Faction and MX vs. ATV, which have yet to find a buyer.
Asked about the future of these series, former THQ president Rubin Rubin told Game Informer: "There will be a separate process to sell off the back catalogue and IP. That process will take place in the coming weeks."
On his own immediate future, Rubin added: “My focus right now is helping the THQ employees who are out of work find jobs. I am lucky enough that this process doesn’t negatively impact my family. That is not true for hundreds of people.”
Earlier this week Sega acquired Company of Heroes developer Relic Entertainment for $26 million, while Volition, Saints Row and the Metro property were picked up by Koch Media for a combined total of $28.1 million.
