Some Of The Best PC Games Of All Time Are On Sale Right Now

Steam kicks off new sales every week, but its latest one is something special. The 0451 weekend sale celebrates the iconic video game Easter egg, '0451,' discounting some of the best PC games of all time. '0451' has appeared in many video games over the years. It's most commonly used in games that some call "immersive sims," where players are given choice in how they play, and the game's systems respond in kind. The 0451 sale runs from now until August 24.

Many of the best immersive sim classics are discounted, including System Shock: Enhanced Edition for $2.49, System Shock 2 for $2.49, and Deus Ex for $1. These are the games that started it all, but a number of the games they inspired are also featured, including Deus Ex: Human Revolution for $3 and Deus Ex: Mankind Divided for $4.49. All three BioShock games are on sale as well: BioShock Remastered and BioShock 2 Remastered are $6.59 each, while BioShock Infinite is $7.49.

The origins of the '0451' Easter egg started as the first door code in the original System Shock developed by Looking Glass Studios--this tradition continued with developer Ion Storm and its classic, Deus Ex. In a Deus Ex Let's Play, producer Warren Spector revealed that the '0451' code was the door code for the original Looking Glass Studios building.
