Yet more Serious Sam 3 DLC is on the way. Titled Jewel of the Nile, this next bit features three more campaign missions, plus more bosses, weapons, and moves -- see it in action in the screens here.
Serious Sam 3: Jewel of the Nile follows the legendary hero to the mysterious Temple of Isis on the island of Philae where a monstrous temple guardian lies in wait. Set in the midst of the events in Serious Sam 3: BFE, Sam and his team will battle through three new campaign missions against the unrelenting hordes of Mental’s forces.
The goods will run you $10, and will be available October 16. Still no word on that console release -- perhaps Devolver is waiting until all of the DLC is complete before releasing an all-in-one version.
