ZDoom

In case you're not sure what I'm talking about, this should help you. I found this a few days ago, and found only this topic.
The download link has expired, so I was wondering if anyone has the wad.

That was unexpectedly hilarious.

LOL! XD

OMG Rick Astley! He'd kill anything, regardless of what was playing him.

Heh, go to the automap and IDDT IDDT to see the music in action.

Shame the projectiles don't have the +dontsplash flag. You can hear them hitting floors with terrain sounds and they make a helluva splash in water when you have a terrain/splash wad loaded.

Thanks! I remember there was an xkcd comic about how trolls finally managed to rickroll Rick Astley. Awesome.

Too bad you can't bash anyone with the stereo.

I think I just created a rival. The wad.

He he, very good - maybe even better - but still noisy projectiles hitting the floor.

Ah, yeah, oversight, just re-uploaded a fixed version

Much better.

@Snowkate709: Nice. With one push of a button (without holding it), I can make them dance and not attack me. Then, I can kill them if I feel like it.

They're no rave guns.

Oh hi I upgraded your blaster:

The Rickroll Blaster now has an additional second attack.
