And yes, it's legit. I just redeemed my key
"Welcome to week two of our absurdly large five-week giveaway, in which we give away up to a million Steam keys each week. The keys are supplied by Bundle Stars, known for grouping top games into money-saving bundles. They also sell games individually at up-to 95% off.
Dino D-Day was released in 2011, but is due a major update soon, overhauling the graphics and moving the game to a sharper version of the Source engine. It's set in an alterna-history scenario in which Hitler creates an army of lizards and rampages across Europe. It's a good enough excuse to jump into the body of a Triceratops and headbutt the marauding menace to death. There are seven playable dinosaur classes, and nine human classes, and dozens of guns. What are you waiting for? Get your free Steam key here."
