The second game mode - the Cartel Challenge - is made up of variations on the same theme of money, drugs, killing, and territory, with its focus being on multiplayer battle royales via local wireless ad-hoc (nope, no online). While the specific goals may change (as the bosses you work for do), the gameplay fundamentals remain the same.
As with all strategy titles, battling friends gives the game some legs when you're done dispatching bodies on your own. This depends on you having some buddies with the game in hand, though, as Game Sharing ain't part of the deal.
