BOOM. You're done. iPhones try to act like it's "just a website bookmark" because they want everyone to go through the App Store but really it functions just like an app... Full screen, moveable icon on your home screen. All of it.
Enjoy.
Install the Channel 3 app from the Google Play Store.
I was a huge fan of this game when it came out. My frustration came with the constant nerfing of guns right after you get them, or max level increase at the same rate as you finally get that top level. I felt like I was being played, and if it didn't affect the PVP play, I wouldn't have minded, but I found it very frustrating.
