If you enjoyed the classic such as Ghosts n Goblins, Bomb Jack, Baluba-louk no Densetsu or Psychic 5 then look out for Radin Games retro inspired game ' Eternum ', which is back in the gaming news again as an enhanced version remade using Unity that's currently going through a Steam Greenlight campaign. Just as before Eternum is being developed with the look and feel of the 80's arcade cabinet games, but this time with all new graphics, gameplay, new enemies and even steam achievements!
According to Back to Basics Gaming and Radin Games, Eternum will have awesome gameplay which may cause addiction, a memorable soundtrack by thewardenclyffe, retro arcade 16-bit aesthetics, plenty of enemies that need to be dealt with, 25 levels, special levels with bosses and a secret bonus for each level. But if that didn't excite you enough as a retro gamer, check out the 3 level demo that is available through the main website
