Do you already have your virtual proton pack strapped on? You better, because you’ll definitely be needing it in battling the biggest paranormal monster yet to come to the Ghostbusters game on iOS.

In Ghostbusters, which is developed by Beeline Interactive, you join Ray, Egon, Peter, and the rest of the titular team as they recruit new Ghostbusters to bust ghosts throughout New York City.

That’s as opposed to the Ghostbusters: Paranormal Blast game for iOS. In this augmented-reality game, which is developed by XMG Studio, you join the Ghostbusters as a new recruit and capture supernatural entities right in your own neighborhood.

But going back to the Ghostbusters game for iOS … The game is an ectoplasmic mix of real-time strategy, role-playing, and management gameplay.

And the game’s first ever update challenges you to take on the role of a true Ghostbuster and strategize so that you may manage to survive the ultimate (at least for now) battle.

I am, of course, talking about the battle against the white, giant Destructor himself, the Stay Puft Marshmallow Man.

Watch out for Stay Puft to stomp through town for a limited time during special Destructor events. When he does, you must take him down to earn special rewards, including power cores and rare pieces of equipment.

In addition to battling Stay Puft, Ghostbusters’ first update lets you:

  • Explore two brand new floors of the tower with new boss battles and blueprints to research
  • Capture four new ghosts and conduct research to unlock new items and upgrades
  • Fill your HQ with haunted housewares like the Dancing Toaster, Dana’s Haunted – Zuul Fridge, and Slimer’s Bed to collect daily rewards
  • Enjoy improved game balance and performance with fewer paranormal bugs!

Compatible with iPhone, iPod touch, and iPad running iOS 4.3 or later, the newly updated Ghostbusters is available as a freemium game in the App Store.

It’s slime time! Or more appropriately … It’s marshmallow time!
