Two retro games in one

Duck Hunt x Doom = You guessed it, Duck Doom.

I actually made this, about 18 years ago. The folks at G4's "Attack of the Show" featured it on TV, and praised it for being mechanically sound, kinda funny, and retaining the feel of both games. My inbox took quite a beating for the next several months.

Here's a little gameplay video: https://www.youtube.com/watch?v=e9amHirFXe8

Getting that feel right involved playing the original games frame-by-frame to study the movement and behavior of the weapons and ducks. The first version only took a week to make. The "Deluxe" version took much longer because I wanted to mix the two games' music as well, and I was quite unhappy with the early drafts. Eventually they got there.

I put a download link in one of the comments. Unfortunately, this was a product of some very basic tools at the time, and it's not guaranteed to run properly in anything newer than *Windows XP*. Maybe someday I'll find the source, dust it off and port it to a newer engine.
