i have herd alot about this sniperfrog thin IW put into mw2 and have experienced it alot some games i can come on top by miles and then in other games with the same people i cant even get a kill
FROM another site explaining it
Have you ever been playing MW2 and thought "that's not right, I shot him first!"? Maybe you ambushed an enemy from behind, blasted him with 5 rounds to the chest, and then he spins around shoots you once in the foot, and you die? Everyone blames lag. Well, it's NOT lag. It's something far worse, and it just may signal the end of "fair" gaming forever.

While investigating the recent claims, and going through the code of MW2, I made a discovery in one of the subroutines of the game AI. It's called "spfg.exe" (we'll call it SniperFrog since all will make sense just bear with me) and it's an AI subroutine that "evens" out the game by lending additional AI resources to a player, or by limiting the player in really cheap ways.

For example, you ever start playing really good, and suddenly you go on a death streak where you can't even barely MOVE without getting killed? You'll get slaughtered like 5 times in a minute? That's the SniperFrog program in action. Alternately, maybe you'll have been having a rough streak, and suddenly you'll go on an amazing killstreak and it feels like you can't do anything wrong? Again, SniperFrog.

The SniperFrog program is meant to "even" out the game. So that ALL players can feel like they're awesome at some points, even if that has to come at the expense of other players doing poorly. It's a plan by IW to sell more copies of the game. You CAN disable SniperFrog by going offline, SniperFrog is dependent on it's concious AI mainframe to work and it's only available online.
