ABOUT THIS GAME
Nordenfelt is a steampunk shoot 'em up game for Windows.
The game is set in an alternative history timeline where steam-powered machines are still the state of the art. Mechanical behemoths are invading the lands, just to get shredded to pieces by you.
It's your turn now to shoot your way through masses of obscure vehicles while dodging hails of bullets. Unlock powerful equipment and send those intruders back to hell even faster.
