Hunted is a game mode in which a VIP (or the Hunted, the Prez or the Civ, depending on your favourite name for the fat dude) must escape the map's confines to score points. A team of bodyguards assists the hunted in attempting to escape, while the assassins attempt to slay the hunted.
The bodyguard and hunted teams are allied and share a common score. The VIP's movements are relayed to the bodyguards via text messages (though we could improve on that somewhat, see discussion tab). The assassin team typically has a player limit of five, to give the bodyguard a reasonable chance of escaping.
Snipers are deprived of frag grenades, and the hunted has Auto Rifle resistant armour. This helps balance things somewhat.
