I've a new game for you guys I've been playing this game for the past 3-4 days and I've had a blast.I've progressed quite far without buying any upgrades.Now I can unlock guns and characters by playing player vs player games.
There's also a zombie game in it where you roam around the city and use weapons to kill your enemies.
I haven't said anything about the store mode yet which is a great part of the game.
You can unlock new characters and guns in it which help you out.You get daily tasks are the same every day completing them get you extra rewards.
