Half-Life 2 Episode One continues the game where Half-Life 2 Ended as the description says Half-Life 2 main game is not required since its a like a standalone DLC but if you are a Half-Life fan this game is a must
We can't say much about the game since is half-life 2 same good graphics, same AI, and obviously new levels and a new enemy.
The bad thing is that, the game is short as expected you can finish it in 2 hours, but still enjoyable and challenging. What are you waiting for? Don't make Gordon wait too long and get this game!
