This game has more action(which it was supposed to be)a better story line, better looking guns, better scripted events, HUMAN INTERACTION. Now those of you wondering if its just a Doom 3 rip off or anything like that, let me tell you, your wrong. The game offers superb voice acting, which is lent by some of Hollywoods fine actors.
You are basically armed with all the weapons from Quake 2(except from a couple), obviously updated, but they keep the names of the originals(Hyper Blaster, Chain gun etc.). This does start to dwindle abit later during the course of the campaign, but still this remains to be a solid fps. With a fair amount of assistance from co-soldiers. Your job is of course to assist in the destruction of the newly created Makeron and the Strogg, the game itself starts off pretty hectic. You, are Matthew Kane one of Earths best soldiers in an elite fighting squad named Rhino. So, earth returns again in a much grand scale to their last attempt to stop the Strogg from wiping out Humanity. After the death of the Makeron in Quake 2 and with the assumption of earth forces that Strogg forces would be in disarray following the death of their previous leader(the Makeron), proved to be wrong. Earth forces return again to battle the Stogg, a cybernetic race which is bent on destroying Humans. It starts directly after Quake 2, which is a good thing even though that game has a fair few years behind it. What a game, the emphasis on this game obviously was the single player, which indeed is awesome. In the wasteland of games that offer intellectual amusement at the expense of enjoyable game play, it offers something games nowadays lack: an experience. Regardless, Quake 4 is an extremely excellent game. Sometimes the player's weapons are *too* effective - I honestly don't know what some of the enemies really look like, as they die and self-destruct before I could get a good look at them. The game is extremely linear, preventing replay from being extremely fun. The hit boxes of enemies is a little odd, often finding that the game didn't register your shot as a hit because the cross-hair wasn't red when you fired. It is one thing to see a computer character stabbed in the heart and then have its legs amputated, it is an entirely other thing to feel as though you *are* the one being stabbed in the heart. It is common in current games to see certain things happen from a third-party viewpoint, but the player's conversion from a human to Strogg is done in first-person. One of the most publicized plot twists behind Quake 4 deserves special recognition. An example of this is when you're in a relatively isolated structure: while you're essentially alone, your fellow soldiers are heard fighting and dying to hold the ground you're on.
While the game is linear (doors there to give the sense of a larger building never unlock, certain doors will only open when the player needs to be behind it) the sense that a major war is going on is never eliminated. Q4's brisk pace doesn't stop at the introduction, with every level giving the player a sense of urgency. You're to go in and create some disarray. During Quake 2, a lone marine assassinated their leader, thinking it would throw Strogg forces into disarray. Whereas many modern games spend a great deal of time in the beginning to explain the plot, Q4 provides you with the required within the small introduction: Humans are fighting the horrific Strogg. The game in question, of course, is Quake 4. It's very telling when a game can take two minutes to show a player something, in a day and age when developers usually spend thirty minutes *talking* about it.
