It is very difficult for a game to overpass the pure quality and awesomeness of Unreal Tournament.
There is not such emphasis on the single-player mode. In fact, there is no need to even look at it, on condition that you are familiarized enough to play the multiplayer. But for the newbies, these scenarios work like a training mode, where you will learn every aspect and secret of shooting games. Furthermore, the difficulty of the game can be set, and indeed there is much difference between low and high difficulty levels, a factor which makes the game very realistic.
Both in single-player and multiplayer modes, there are different types of battles. The player can participate in a Deathmatch, which is the old and classic battle where everyone fights for himself, or in a team battle where two teams fight each other. There are also modes like Capture the Flag and Domination mode, which give the player a fantastic variety to play in reasonably good battle modes.
Another interesting thing to mention about the game is the very good and customizable weapons you can use. in Unreal Tournament, the weapons not only look and sound better, but they also perform better and more realistic than almost every other FPS game. There is also a great balance between the weapons: none of them is amazing or useless. Of course in the beginning you may face problems using these weapons, but after a while there will be no problem.
Unreal Tournament also offers great graphics and visual effects, detailing every environment and character to the maximum level, while there is no problem with the system requirements nowadays, so you can see the game at its best. And the music of the game gives you inspiration and rythms your play.
Unreal Tournament is a game different from the ones of its genre, perhaps due to its perfect performance which gives you a great time, if not total satisfaction.
