Bethesda and id Software's catalog of titles on Steam have been discounted to a tremendously marked down price point of $99.99 for the duration of this weekend, as part of the annual QuakeCon event.

The bundle, which is marked down from $456.59, includes all the Dooms, Quakes and Elder Scrolls titles on the platform, but does not include the recently released Dawnguard DLC pack. By pre-ordering Dishonored on Steam, you can actually mark the bundle's price down to $79.99 — and grab a free copy of Arkane's Arx Fatalis for free, to boot.

Each day during QuakeCon 2012, which runs from today through Sunday, August 5th, a different game or franchise will see its own sizable discount.

• Thursday: The Elder Scrolls Sale, with up to 66 percent off
• Friday: Rage 50 percent off
• Saturday: All Fallout titles, including DLC, are 66 percent off
• Sunday: All id games are 75 percent off

In addition, all of id Software's iOS titles have been marked down to $0.99 for the duration of the event.
