(Image credit: Valve) Update - January 7:Portal: Revolution is out now as a free installation on Steam. All you need is a Portal 2 copy. Update - January 6:Portal: Revolution has been delayed, mere hours before the conversion mod was supposed to be unlocked on Steam. Modding team Second Face Software published ablog postto clarify that “the game is done” and could “ship at any moment, butValvehas yet to review and accept the game for release.” Second Face attributes the long wait to the holiday period that has Valve running with a skeleton crew, although the wait shouldn’t be too much longer since the storefront is supposedly reviewing the mod now. Original Story:Portal: Revolution is the newest community-made mod for (arguably) the best puzzle game in existence, and the best part is that it’s out today. Portal: Revolution serves as a prequel to Portal 2, set in the same crumbling Aperture Science ruins with greenery growing over concrete and clinical wall tiles. But it’s essentially an entirely new game with over 40 test chambers, fully-voiced original characters, and a unique story delivering around 8-hours of content. According to the mod’s storefront description, the “puzzle difficulty starts where Portal 2 stops” - so you might want to finish Valve’s twisting comedy before jumping into the unofficial prequel. You need to own Portal 2 onSteamto access the mod either way. Despite starting on the tougher side, Revolution will still teach you about all its new toys and tricks before throwing you into the deep end with the deadly test chambers. New elements include a laser cube variant, rain that cleanses gel, and over 15 puzzles that somehow only use the blue Portal gun. Sign up to the GamesRadar+ Newsletter Weekly digests, tales from the communities you love, and more Revolution certainly looks like a worthwhile few hours for Portal fans. Even though Glados’ searing, passive-aggressive jabs will be missed, the prospect of more mind-mending head-scratchers is definitely an exciting one. I’m far from the only one who’s pumped for more puzzles, though, as the project’s most recent trailer surpassed a million views onYouTube. There’s clearly an appetite for more portalling -don’t say it -if only Valve could count to three. For now, check out thebest puzzlersthat remind us of Portal and Portal 2. Or see howPortal speedrunners are ripping through records with the help of a coffee mug.
