GTA: Tequila Zombies 2
You are on your way out of the borders with your hot girlfriend when it happened. Your girlfriend turns into one of the undead and attacked you. Fortunately, someone shot her to save you. You fell asleep that night and when you woke up, you meet this lovely lady, who is a cop. In this game, you have two choices, either be the guy or the lady. The idea here is to survive the zombie onslaught. Each kills earns you money. Some zombie would drop some weapon and tequila, which you can use later in the fight. The game would be harder, so you need the tequila for the boss fight.
