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 haven't played it enough to fully know what I'm doing when I go in (I usually play with a more experienced friend and just follow his lead), but it is definitely well done! You (and any friends delving with you) are a bunch of space dwarves mining asteroids for..... stuff? Problem is, there's bugs. Literally. You have to get through these tunnels (and you have tools to dig your own paths) to your objectives, all while fighting off tons of huge bugs. It's fun, chaotic, it lets you be creative as you can use the tunnels you dig to create choke points and kill zones (or you can just kill zone yourself), and you're freaking dwarves in space. How is that not fun?
