Holy sales, Batman! Arkham series and Metro lead this week's deals

If you're a PC gamer looking forward to Friday's release of Batman: Arkham Origins and have yet to scoop up the previous two entries in the series, now might be a good time to do so, as they're 75 percent off on Steam until Monday, 10 am Pacific. That makes Batman: Arkham Asylum just $5.00, and Batman: Arkham City just $7.50. Both versions are Game of the Year editions, meaning even more batarang for your buck.

Not a bat-fan? Amazon has unearthed savings on Tomb Raider and Metro: Last Light, which are both on sale for $19.99 through the week, while Best Buy is helping aspiring gamer musicians get into the groove by taking $50 off the cost of any electric guitar when you buy Rocksmith 2014. Lots of good things on sale, stranger.
