I have high expectations for Half-Life 2: Episode 3, and I'm really impatient to play it.
As you've probably learned in Episode 2 (If not, leave this thread and go beat HL2: Episode 2!), Half-Life 2: Episode 3 will mainly happen in the Borealis, a "legendary" ship of Aperture, Black Mesa's rivals and the creators of the famous Portal Canon.
What I believe will happen in HL2: Episode 3...
- We will discover a working Portal gun in the Aperture ship.
- The G-Man will have a WAY bigger role in this Episode than any other Half-Life game.
- Alyx Vance will be darker, not joyful as usual. The death of her father will make her eager for vengeance against the Advisers.
- We will probably kill an Adviser with the help of the Portal gun + Gravity gun.
All I can say is that the Gravity gun AND the Portal gun in the SAME GAME will make Episode 3 the best Single-Player FPS game I'll ever play, if we can actually use both those guns in the game.
Your thoughts?
