Steam is offering a very nice weekend deal featuring the Oddworld titles Abe's Oddysee and Abe's Exoddus at 75% off, that's only $2.50 each.
Additionally, purchasing the two together will net you additional savings, with Steam offering a package deal at $3.75.
Sean @ FG: From inception to their first release, explore the history of Oddworld in the words of those that made it.
PC gamers shouldn't miss out on these awesome freebies on Steam right now. If you grab them in time, they will be yours to keep and play at your leisure.
Abe's Oddysee is a must-play for anyone who didn't play it back in the day, one of the best platformers IMO.
Oddworld Inhabitants is currently offering free copies of Oddworld: Abe’s Oddysee on Steam for a limited time. Contrary to most of Steam’s offerings, this isn’t a free to play offer: once you download and acquire your free copy of Oddworld: Abe’s Oddysee, you will be able to keep it forever.
