Dead Space 2 on Steam continues to be horribly broken while they fix Doom 3, a subpar game nobody plays.
Hilarious.
See, buying Dead Space 2 on Steam rewards you with a DLC "feature" which makes all items in the shop free - even the most powerful ones. All the prices are FUBAR'd.
You can go around that and redeem Dead Space 2 code via Origin, and get Dead Space 2 v1.0, which does not have that problem - unfortunately it has a game-breaking bug which creates constant noise and mini-inventory never goes away from the screen.
The sane solution, I suppose, is to get a pirated cracked patched version, but at this point I am too tired to bother.
