The glitches in the game of Splinter Cell...

I had played the Splinter Cell game and finished the Game. I haven't encountered or notice any glitches. It might be some problems during installation.

i think these glitches caused by hardware compatibility, i was playing this game and found the same problem when i replaced my VGA card with the best one (Radeon) the problem not found anymore

Well, I've played splinter cell: double agent, and I don't think that's the one you're talking about here. But I did come across some in that one, like when fisher is like walking halfway through the floor in some places, like he's a ghost or something, but no huge glitches.
When it comes to glitches, yeah, so many games have those, glitches or bugs, as they are called. It is more prominent in copies of games and rarely occur in the original ones. I don't mind glitches as long as they are not game-stopping glitches that are saved every time you save the game, which usually means you'll have to start the game all over again.

I agree, Splinter Cell is one of the best Ubisoft games in existance today,and I have beaten it so many times that it aint funny,as for glitches,I have never had the glitch with the cigarette guy,even though I used to play Splinter cell on gamecube,and now I have an X-box and I have noticed that the scene is a little different,and I dont think I noticed the other glitch either.What system do you play Splinter Cell on?I cant remember coming across any glitches,even though its been a while since I played Splinter Cell,what other glitches have you seen?As for why you have seen these glitches,maybe it has something to do with your Splinter Cell disk, maybe when they made that copy they messed something up,or maybe the glitches are susposed to be there,but only a few people actually see them,other then this I dont know,but I am sorry that you have to do parts over and over because of them,and you might want to buy another copy of Splinter Cell and play it and see if you still run into the glitches.
