The PC version of Ubisoft's Assassin's Creed has been marked down to just $5 on Steam as part of a midweek madness sale. The sale will run up to Thursday.

Called the Assassin's Creed: Director's Cut, the PC game features four extra mission types over the console version: archer assassination, rooftop race challenge, merchant stand destruction challenge and escort challenge.

If you skipped the first game but are eying the sequel, now is the time to buy in: Assassin's Creed II (360, PS3) hits stores on November 17. Thanks to Evil Bones for the heads-up.

No longer content with mere weekend sales, Valve has announced that this week will see its digital storefront Steam discount one Ubisoft-published PC title daily.

The promotion kicks off with a 50% discount on Ubisoft Montreal's open-world murder simulator Assassin's Creed, which brings the game's price down to $9.99. That price is only valid for today, Monday, March 23.

Other titles published by Ubisoft, but not guaranteed to be part of the sale, include Far Cry 2, Tom Clancy's HAWX, World in Conflict, Grey's Anatomy: The Video Game, Tom Clancy's EndWar, Prince of Persia, and Brothers in Arms: Hell's Highway.

I wasn't crazy about Assassin's Creed when it hit consoles last year. Now Ubisoft is trying to win me over a second time with the PC port, offering a set of extra missions to bolster the original game's content. Are they enough? And what about those insane system requirements? I took the game for a long spin, and spit out some words.

Rather than forcing bench-sitting as a prerequisite to murder, the designers have now allowed you to complete several other, less tedious challenges that fulfill the same function. Players will have the choice of participating in timed rooftop races, archer assassinations, merchant stand destruction, and escort challenges, in addition to the five previous tasks. All are fairly self-descriptive, and all serve to infuse the investigatory intermissions with some much-needed life, by way of additional death. Read more..
