More beautiful pixel artwork from the Atomic Runner article.
Atomic Runner looks so nice I had to make a gif, even if I didn’t manage to get it into the actual article.
freaking out over the bird boss in Atomic Runner aka Chelnov (Genesis - 1992 - Data East)
heavily modified port of a 1988 arcade game
from Wikipedia: “The game’s plot was changed completely, where Chelnov is not a coal miner caught in a nuclear meltdown, but a regular human-being wearing a special combat suit who battles enemies to rescue his younger sister. The game’s enemies and background images were also changed to those reminiscent of an ancient civilization.”
