GAME DISC ONLY
From Wikipedia:
The game begins as Zak and Fiskerton are watching Weird World. Argost introduces his show with a rambling about being afraid of the dark. He states that the Aztecs believe that we have burned through 4 suns already and we live under a 5th sun or as he calls it the "Sun of the 8 Beasts". According to the Aztecs there will never be a sixth sun and closes with "Are you afraid of the dark NOW." Mere moments later, the Screens flash intruder alert and Drew tells Zak to stay but Doc asks that he helps check out the place. Using Cryptids that had broken into the facility specifically a Cafre and Fiskerton to fight off some of Argost's minion's. Shortly thereafter Zak fights a Kingstie as a mini boss followed by Van Rook (who had stolen files on various Cryptids) as the main boss.
