Osama bin Laden may have killed time by playing video games such as Counter-Strike while he was holed up in his Pakistani compound, according to files released by the CIA.

The al Qaeda leader’s computer included a trove of documents along with files for several popular video games with themes such as war and terrorism, Newsweek reported Thursday.

Among the games in bin Laden’s files were the first-person shooter Counter-Strike — in which soldiers battle terrorists in urban warfare. The game also allows users to face off against each other online.

Another title in his collection was Half-Life, a science fiction shooter game where the player tries to blast themselves out of a faux-nuclear facility.

Also in bin Laden’s game stash were Super Mario Bros., Final Fantasy VII and several Dragon Ball Z titles, Newsweek said.
