Hey - hey! That downloadable content isn't going to download itself, you know. Those PC versions of Resident Evil 6 and Resident Evil: Revelations aren't going to just acquire those luscious mini expansions willy-nilly. Just as well, then, that Capcom are throwing a huge DLC-focussed sale for virtually all of their titles presently available on Steam, from the Resident Evil series to Street Fighter IV: Arcade Edition to Lost Planet 3 to, well, whatever else Capcom have cooking up in the Steam store.
Here's the link to everything they've got; alternatively, if you've only a taste that the Resi franchise can appease, here be the links to Revelations and RE6, for your convenience. Happy DLC collecting, bargain hunters.
