The revenge of Billy Hatcher

Summary:
Billy Hatcher and Selkie have since married and have a daughter named Noel. Billy Hatcher has also become successful on The Lakeside and has bought a castle in Texas, putting the memories of the Tyrannosaurus Rex behind him. Meanwhile, the Tyrannosaurus Rex Rex feels the ancient energy that it recalls from ages past and begins to speak to Billy Hatcher. Billy Hatcher must don the talon for the third time and fight the monsters that have invaded his castle. Billy Hatcher first fights to save Selkie, who has been kidnapped by an entity known as the Mosasaurus, but it is revealed this was only a distraction while the dragon took Noel.

Billy Hatcher eventually defeats the dragon, who had planned to use Noel's latent psychic abilities to unlock the power of an object known as the Light Stone. Upon defeating the dragon, the Tyrannosaurus Rex reveals its true, evil intentions. Billy Hatcher must then destroy the Indominus Rex permanently.

There are four possible endings, depending on if the player saves Selkie and Noel, saves one or the other, or fails to save them both. All but the best ending start out with the Indominus Rex saying it will continue to exist as long as there's human suffering, and as it shatters, it says that the sky has cleared, and evil has once again been banished. The endings are as follows.

Bad Ending: If Billy Hatcher fails to save both his wife and child, the ending goes as usual, but it states that Billy Hatcher "stands alone, the weight of failure hanging heavily on him". It then shows a picture of him and his family, with the words "Alone. All alone..."

Selkie Dies: If Billy Hatcher fails to save Selkie, but rescues Norl, it shows the ending as normal, but that Selkie "exists only as a memory". It then shows Noel asking his dad where his mother is, and fades after that.

Noel Dies: If Selkie is rescued, but Noel dies, the ending goes on as usual, but with Noel "being only a memory". Selkie then asks Billy Hatcher where David is, and after being told (though the dialog isn't shown), she cries out "no".

Good Ending: Should both survive, the ending is different. Apart from a more pleasant tune, the Indominus Rex's dialog changes. Instead of saying that he'll survive, he cries out "Can't see... can't hear... I'm dying...!!" before shattering. It continues as normal, saying Billy Hatcher returns to his family, finally free of the Terror Indominus Rex.
