Unreal and Unreal Tournament, the first two titles to use developer Epic Games' now hugely popular Unreal engine and which spawned an entire FPS franchise, are now available to download and play for free via the Internet Archive. And yes, it's with Epic's permission.

Released in 1998, Unreal and its 1999 multiplayer-focused follow-up made a splash at a time when FPS titles and online multiplayer were beginning to catch fire. Quake 2 released in 1997 and spawned an online multiplayer phenomenon--one that Unreal was quick to follow up on. Epic's graphically impressive and fast-paced arena shooter spawned multiple sequels, with the last, fully released entry being 2007's Unreal Tournament 3.

Epic did release a pre-alpha build for a new entry in the series, simply called Unreal Tournament, back in 2014. However, the game was officially canceled in 2018 as Epic shifted all of its focus to its money-printing battle royale juggernaut, Fortnite.
