This is one of my favorite games of all time. This is the best FPS (First Person Shooter) I have played to date, so when this first came out it blew me away. There's a great multiplayer combat mode where you can make a custom character with two options (Head and Body). You can face up to 8 sims. You don't need two players to play the combat mode. You can make teams (So you don`t have to kill your friends). You can make a custom list of weapons. It saves your stats on your player profile and gives you awards. You can create a whole game (Enemy Sims, Level, Weapons, Limits, and teams) and save it. If you like any FPS games, you have to get this one!
