10 DOOM Classic
Released in 1993 for MS-DOS and later ported to multiple other platforms, DOOM was a pioneer and trail-blazer of the now ubiquitous first-person shooter (FPS) style games, which have over the years become increasingly popular among PC and console gamers. Now, players can relive the thrill of the original DOOM — all four episodes spread out over “36 levels of non-stop carnage and action” — on their iPhone or iPad. Explore the surface of Mars and engage with a variety of weapons to defend yourself from the demonic forces stacked against you. DOOM can be downloaded now for just $4.99 from the App Store.
