EA really, really wants you to give Origin a try. The latest initiative to get you to sign up is pretty convincing though; it’s called On the House and it involves EA throwing free PC games at you.
Do you want a copy of Dead Space for PC? Good. You can have one. For nothing (except an Origin sign-up.) You don’t even need to decide in a hurry, because the game can be downloaded for free until 8 May.
Dead Space isn’t the greatest PC port in the world, and has some specific issues with mouse input. You can mitigate this slightly by (if I remember correctly,) disabling v-sync. Or you could use a controller instead, which avoids the problem entirely (unless you don’t want to use a controller, then it just adds a different problem.)
According to EA, ‘On the House’ specials can “appear and disappear at any time.” It doesn’t mean they’ll disappear from your library though; the publisher says that once Dead Space is downloaded, it’s yours to keep. That is to say, as much as any digital game can ever be said to be “yours,” anyway.
There isn’t any indication of what game might be next in line for this treatment, but the fact that the scheme has a special name suggests more titles will be on the way at some point in the future. For now, Isaac’s original survival horror space adventure is yours for free.
