Hard Reset is an awesome game and I can't recommend it enough if you like slick, fast paced shooters.
To enter you must post your favourite Quake memory. A cool play session, favourite map, nice kill, anything like that.
If you haven't played the original Quake you should be very ashamed of yourself. And you should describe an awesome moment with a game most similar to Quake.
The winner will be picked by random.org, with a "gamecheck" done by me. Just so that if your "closest game to Quake" was SpaceChem (albeit it is also awesome), I know that you're not really into Hard Reset ;-P.
As usual, please enter only if you really want to play that game.
It will be the Steam key of that game, not only because there is no "single Desura key" in the bundle, but the Steam version will get a massive content update later this month.
