Hey all last night I was thinking about a game I would like to see here but I can't remember it all it. ALl i recall it is was in the 90's and a demo from PC gamer. I do recall it played kind of that Flock game but I just can't remember the title's name.

Sheep?

Huh, I've never heard of this, but it looks pretty fun.

Lemmings?

For some reason, all I can think of is The Horde.
Not exactly like you mentioned, but now I can't get it out of my head. I remember playing a demo, but I don't know if it's available these days.

Need for speed?

Capitalism Plus?

LOL, I see what you did there.

Nope none of them, tho Lemmings would be nice. After taking time thing to think about it I remember a UFO and cows.

Do you remember anything else about it? You say it played kind of like flock but was it the same top down 3d or was it maybe 2d? Remember anything about how it looked?

It was a top down view, again like flock, and it was cartoon like in terms of the art.
I recall flying around with the UFO and picking up cows and dropin/throwing them.
if it helps any I recall the game being on a timer for the demo and after the time was up it asked if you wanted yo buy the game and in put a key. I recall this bc this was the first time i ever seen a CD key input for a game.

Here's a link to Flock for those who don't know what you mean.
