"Serious Sam 3: Jewel of the Nile follows the legendary hero to the mysterious Temple of Isis on the island or Philae where a monstrous temple guardian lies in wait," states the sales pitch. "Set in the midst of the main Serious Sam 3: BFE storyline, gamers will battle through three new campaign missions against the unrelenting hordes of Mental’s forces including the re-introduction of two familiar monstrous faces. Sam’s arsenal of awesome expands as well as the two secret weapons from the main Serious Sam 3: BFE storyline -- the laser gun and sniper rifle -- make their way into the spotlight in Serious Sam 3: Jewel of the Nile."
Neat! More Sam is good Sam.
