Unreal Tournament was one the the greatest shooters in its time with great gameplay and tons of extra modes and features which made it one of the greatest shooters ever. One of the high points in UT is the grafix which were superb in its day and still look good today. Another high point is variety with many weapons and match types to play with makes UT a enjoyable to play for a long time. Plus it only cost about $8 or $10 so I defiantly recommend you try it if your computer is fast enough.
