Help me remember the name of a FPS video game

I’m trying to identify a PC video game that I played about five years ago, but it may be even older than that. It was a pretty famous game, a FPS with lots of levels, and the main weapon was a glove that shot green organic blobs that could bounce around corners and kill enemies.

Not much to go on, I know, but any help would be appreciated.

Rise of the Triad: The Dark War

I appreciate the response, but that’s not it. It was more like Half-Life or Unreal in graphics (and I can’t be sure it wasn’t a version of one of those), and the spores the thing shot were definitely green. You could get a bunch of them from certain plants, but they would also slowly regenerate in the gun, so you never completely ran out of ammo.

Unreal Tournament 3

Nope, it was a single player game. A little more is coming back to me. The gun or glove or whatever was kind of alive, and during lulls in the action the avatar would stroke it like a kitten.

Sounds like one of the Half-Life sequels, maybe Opposing Force.

I didn’t play much of it, but it sounds like it could be Prey.

It’s definitely Opposing Force. That fish gun was easily the best part of the game, although the rest of it wasn’t bad. On sale on Steam right now, I dunno if it’s gone 75% off yet this season though.

YES!! That’s it! For some reason I thought it was a glove, and googling for green spore glove got me millions of hits about gardening, so I couldn’t find it.

Thanks very much, Dopers.

ETA: And reading about the game, I see that I was conflating it with the hivehand.
