AA member fultonbot has posted about a new homebrew game in development for the Atari 7800 called Into the Void. The game is a horizontal shooter and you can test it here: JS7800: Into the Void
The game is 160A with 16 pixels zones using 160A 4-color sprites and doublebuffering. It's being built with Atari Dev Studio and right now it is only using TIA sounds, though POKEY has not been excluded as a possibility. The plan is for the game to have AtariVox and High Score Cart support.
