User Rating: 9.4 | Unreal Tournament 2004 (DVD Version) PC
When I first got this game it was like, yeah another FPS, another online experience, boy was I wrong when I said just another FPS. This game makes many other FPS, from Doom to Quake to Battlefield, just seem mediocre in comparison. After playing this game I could go back to those, thats how good and fun it is. If you want a great online experience then this is your game.
This game has many of the standard FPS stuff but were it adds another layer of depth that gives it legs. The game has plenty of modes to suit many types of players wants and needs, from the massive team matches like onslaught and assault, to the out-there modes like bombing run and mutant, to the classic deathmatch, there is a mode here to suit everyone.
The assortment of guns, from the shield gun( which can be used offensively to) to the shock rifle, they all seem balanced and no one gun seems to powerful. For example, when you first kill someone in like 3 hits with a rocket you may say, hmmm this weapon is sweet, until someone snipes you from long range with the lightining gun or shock rifle. Then there is the dodge, sort of like a jump while moving really quick in the direction you want to dodge in. But that is not all, if you are near a wall you can essentially wall jump off of it using the doge, a creative and extremely useful move. The levels that come with the game are overall great but when you add all the user created maps and mods, the second you get this game add the area master gamemode mod, give the game huge amounts of replay. The single player is good but it is really there to prep you for the online, with only a couple of unlockables and such.
The online is were this game truly shines, the community for this game is great and Epic Games is still coming out with new content and patches for this game. The matches are fun, fast and exciting, though this might depend on what server or how good the people you are playing are. I suggest that you get some friends to get this game, it only makes it that much funnier. But there is one problem with the online is that which is finding people of your same skill level can be somewhat difficult, but other than that the online is great and one great feature built in is that if you don’t have a map, say it is a custom map, it downloads that map and all the sounds and stuff for the map, right off of the server.
The sound in this game, though while not perfect, is pretty good. The music is okay, sort of like rock without lyrics, but you can also add your own custom soundtracks and listen to them while you play. The game also has nice ambient sound effects, like on outside levels you can here animals and stuff. The weapons each sound distance from each other and the sounds that each weapons makes sounds just right.
The graphics for this game are awesome and even now don’t look dated or old, they just have this certain style to them that even when not on the highest setting the game still looks great. The physics system is awesome, you can land on someone from up high and kill them, and the death animations are very fun to watch. The levels, as mentioned before, are great and the Onslaught levels are particularly interesting, though classic deathmatch maps like DM-Rankin are still among my favorites.
Overall this is a fantastic game that offers many hours of fun right off the bat but is supplemented by the huge amount of online user created mods, such as red orchestra, that truly give this game a leg up on its competition. From the great graphics and sound to the endless hours of online fun to be had this is the game to get for any online FPS fan.
