The Quake series is undoubtedly one of the most popular in the first-person-shooter (FPS) genre ever. The first iteration of the series is considered by many the father of multiplayer deathmatch also, so it's no surprise that as we get closer to the estimated release date, more people are speaking about Quake 4 and the game's potential.

After having a closer look to the game, and a brief chat with one of Activision reps, we bring you our preview of Quake 4, so you can know a bit more of what to expect when the game is released by the end of this year (not official yet).
