Retro. is an Action-Adventure Strategy game for the Nintendo 3DS. It is one of the first games to utilize the 3DS Achievement System.

Story
One day in the land of Pixellion, a young Blik named Bit and his sister Byt (Bit and Bite) were playing the traditional Bitling game of PixLxiP, a game where you have to control all of the bits in your color, and Byt was winning. Everything was happy, cheerful, care-free, when all of the sudden, Byt got a call and had to leave.

Meanwhile in a government facility, two men named Colonel McBite and Ait were creating an elixir to make the strongest, most powerful Blik soldiers for defense against the dreaded Planet of Polygannial. The Polygans (residents of Pollygannial) are humanoid aliens that want to take over the planet of Bitts. While testing the formula, the elixir was spilled all over Ait, a government scientist, turning him red, and making him evil. He stole the formula and ran off.

Back in the town, Bit was waiting for his sister who had left about 5 hours ago. When he decided he should go and try to find his sister.

Gameplay
The gameplay of Retro. is to let gamers who have not played the 8-Bit or 16-Bit games to try them on the 3-D system. The game is 8-Bit, like the Megaman games, and is a sidescroller game, like Zelda II.

The gameplay is also similar to that of Super Mario World. As there is a special world (Sky City-Star Road) ghostly areas (Haunted Peak-Ghost Houses) and switches that do special things on the map (Door Stompers-! Switches).
