Reports of vouchers included in copies of II grant access to an upcoming of Tom Clancy's Splinter Cell: Conviction, we learn today.

Those leaked copies of Assassin's Creed II we reported on yesterday have more than just Ezio's Renaissance-era adventure in store for you. According to several reports at NeoGaf, a voucher is provided for downloading a demo of Splinter Cell: Conviction.

Sorry owners - the codes are only packed inside 360 copies of Assassin's Creed II, which makes sense when you consider pledged Splinter Cell: Conviction to Xbox 360 and only.

Aside from a couple retailers that have broken the game's street date, you can grab Assassin's Creed II and the rumoured voucher tomorrow in the and on Friday in Europe.
