GG.US has a sale on Orign Games, Dead Space, Crysis and the lot for 66% off
worth mentioning concering Dead Space 3 is Awakend
is $3.40 and Tau Volantis
on a side-note:
While Awakening is great at even 50% off, you mileage may vary with Volantis, it has the Bot Speed upgrade, which is effectively inferior to the Bot Capacity upgrade (sold seperately), since you can mine resource-depots only once, so the capacity upgrade gives you 2x the resources, while the speed upgrade only gets you 1x resources in half the time. The gun modules are decent, they say.
But it's not like DS3 isn't throwing resources on you, ayway. I got my Suit and Stasis maxed out in about half into the game. Stasis is you best friend! Volantis goes rarely on decent sale, so, just saying :)
