Have you missed out on Visceral Games' space horror epic Dead Space? Well then you may want to head over to Origin and download a free copy of the excellent first game in the series.
This is the first game that EA plan on giving out freely to Origin users as part of an initiative called On the House. From time to time EA will offer free games and expansions for a limited period.
Dead Space will remain free until May 8, so there's plenty of time to redeem the offer still.
