Fnvader is an arcade shooter for two players, either against a human player on the second controller, or the CPU. A solitary invader (who seemingly got lost on his way to a Space Invaders cabinet) descends down the screen at increasing speed. Every time he is hit, he re-spawns two rows higher. Once he reaches the same row as the player ships, the game is over and the winner is declared.
Arlasoft have created a new Channel F, Fnvader, game based on the C64 homebrew game, 1nvader by Darren Foulds.
