Here’s a crazy little game for anyone who ever wondered what it would be like if the universes of Duck Hunt and Doom were to collide.

Featured in Duck Doom are several Doom sounds and weapons, which the player can sequentially unlock at certain levels throughout the game. The style of play is naturally very similar to the NES counterpart.

The download checks out at around seven megabytes, which isn’t surprising given the fact that every Doom weapon is represented here. It’s a great way to kill a few minutes, but the novelty wears off fast.
