As many as eleven titles were pulled from the Marketplace for being unlicensed titles as id Software's new owners flex their muscles to protect their newly acquired IPs.

Versions of DOOM, Quake and that were unofficially developed for Google's mobile phone platform have been pulled as ZeniMax have filed a copyright complaint under the Digital Millennium Copyright Act (DMCA).

While DOOM source code is now open source, the developer of the version of DOOM on Android gave an indication to Android and Me, of why they believe ZeniMax had his port pulled and insisted that the game was still available via download on the internet.

"Although the source code, was open sourced, and the application was based on a port of the PrBoom engine, the application is still suspended. My mistake was allowing the download of the Plutonia and TNT WADs, at least that is what I suspect. Although I may not be able to distribute the application through the Market, the APK can still be downloaded and installed through the web," said a representative of L!th!um.
