Denise got killed in my Grand Theft Auto: San Andreas game. Will I still be able to use two players?

I agree

Oh damn. Lets hope my other girlfriends won't get killed then... :P

tu just need to find the same icono that appear outside your girlfriends house : ) There one around Big Smoke, one in one of the little city on the first island and one close to Woozie's casino (if tu have gotten that far) : ) tu can find guides on YouTube, to make it easier to find them : ) Plus tu can choose between several people tu want to be : ) Like a Groove calle Family member, a Ballas, a whore, a stripper, a cop and others :D
