A Preview of Half-Life 2: Orange Box from IGN:
"After playing four maps and testing out all nine classes in Team Fortress 2, it seems this game should be another of this year's entertaining arena shooters. It comes as part of the Orange and Black Box packages, which both contain Half-Life 2: Episode 2 and the first-person puzzler Portal. Like any team shooter hoping for longevity in the online space, the game needs an emphasis on teamwork. Valve seems to be on the right track in this department, with many of the classes complementing each other in specific, effective ways. Instead of being able to select a game mode and map separately, Team Fortress 2 fuses them together, meaning when you pick a map, you're also picking a mode. 2Fort, the most prominent map from Team Fortress Classic (TFC), will feature capture the flag, whereas the remaining five will have variations of control point capture modes."
