Codemasters continues to fight a cold war against game piracy in preparation for the release of Operation Flashpoint in early September - 7th June 2001


Codemasters' effective anti-piracy initiatives receive an additional push with the introduction of FADE(tm) a unique PC-based piracy protection system that can degrade gameplay if a counterfeit copy of the game is identified as being played.

Created for the early September launch of the mighty military simulator Operation Flashpoint, one of the most anticipated PC games of the year, Codemasters has equipped Operation Flashpoint with embedded coding that can recognise the difference between counterfeit and real copies of the game's CD.

If a pirate CD is identified, the game automatically disables key gaming features and instigates a number of subtle changes that adversely effect gameplay.

Anyone attempting to play an illegal copy of Operation Flashpoint will begin with a game that looks and plays just like the real thing. However, over a period of time, the game gradually self-modifies and degrades elements of play to a point where the game is no longer playable.

This system of anti-piracy not only puts off the pirates from duplicating the game CD but is also preventative in putting off people who would purchase a pirate copy from doing so. Indeed, no matter what a pirate may say, anyone considering getting an illegal version will not be convinced they'll get the fully-playable game.

The use of FADE(tm) will be displayed during game installation, saying "Original discs don't FADE(tm), in order that players who experience problems will be aware that their CD is potentially an illegal copy.

The FADE(tm) system used in Operation Flashpoint is created using a combination of Codemasters' own technology and commercial products. The game will additionally be protected with secondary copy protection technology and use FADE(tm) as an additional tactic against counterfeiting. The concept of FADE(tm) is adapted from a similar system employed by Codemasters' PlayStation game LMA Manager 2001, which reduced the amount of pirated CDs in circulation and enhanced sales performance.

Comments John Hemingway, Codemasters' Development Director: "We continue to act against the trade of counterfeiting software with new and innovative systems. In addition to protection that attempts to prevent illegal duplication, we are building Operation Flashpoint to include FADE(tm) as a second level deterrent and I am confident we shall see this effort reflected in the additional sales performance of the game."

Codemasters launches the hotly-tipped Operation Flashpoint on PC CD-ROM in early September in North America.
======================================================
基本上是Codemasters跟Macrovision (又是這家 )搞出來的新玩意
技術是在CD上置放刮痕, 燒錄機在拷貝時一定會自動修正
遊戲安裝後如果偵測不到這些刮痕那在執行半小時後會讓遊戲變的非常難玩
除此之外, 還可以搭配序號及SD/SecuRom作多重保護
目前已知使用FADE技術的遊戲有Operation Flash Point
國外部份論壇表示FADE似乎還會耍賤, 安裝任何使用FADE的遊戲後CloneCD及DaemonTools就無法執行了, 不過酒精似乎不受影響
ps. 上頭的2001應該是2003, 不知為何新聞稿會錯
剛搜尋過FADE確實是最近才出現的東西
