excellent downloadable title Lara Croft & the Guardian of Light at 50 percent off, which means the co-op adventure can be yours for 600 Microsoft Points (that's $7.50). That's quite inexpensive for some time with Lady Croft. We'd say "cheap," but she ain't cheap.
Also available today is the free Kane & Lynch character pack for Guardian of LIght. Don't ask questions, just let the weird wash over you.
Finally, there's a dose of randomness with a pet monkey for your Avatar, half off for 120 MSP ($1.50). "He's not horrible. He's lovely. He's a lovely little monkey."
