Pocket-Now: Remember Doom, the game that helped popularize the first-person shooter genre? Well, now you can relive memories of blasting away demonic enemies through a Doom-themed Live Wallpaper on Android. It features the “Doom Guy” battling it out against familiar monsters from the original game. He wanders around your home screen until enemies spawn, then he fires his weapon until they drop or explode. The wallpaper features some interesting interactive elements and settings too.
