I thought that might be the case. You have my preorder anyway :)
Zapper support, for a second player, has now been added to the final game. :)
Purchased! Now for some 2-player with the kiddos :)
Awesome. Player 1 still uses a controller, but plugging in Zapper to controller port 2 should just automatically work when playing the game (no need to select any options), assuming you're using a CRT TV. Have fun! :)
