Fight Night Round 4 is Electronic Arts' 4th entry into the boxing series. This time around, you have over 40 athletes to choose from from a variety of eras and weight classes, including Evander Holyfield, Floyd Mayweather, and (most notably) Mike Tyson and Mohammad Ali.
In addition to the default selection of fighters, you can make your own customized fighter using a powerful set of creation tools. The most impressive among these tools is the ability to use a PS3 camera or EA Sports' own website to upload pictures of yourself which will then be used to create a customized 3D head for your created boxer.
These custom-built fighters can then be taken into the game's "Legacy Mode", which starts you out as a 19-year old amateur looking to make a name for himself in the boxing world. You will partake in numerous fights spanning your entire career, improving through the use of mini games between matches.
Winning championships and defending titles is also an option, with the number of special challenges completed during your fighter's career determining how effective they are once added to the game.
Fight Night Round 4 features an online world championship, which will rank you against every other player in the world in the same weight class as your fighter. Wins and losses are kept track of in this mode.
The game is available for release on the Xbox 360 console and was released on June 23rd, 2009.
