[PC] Origin FREE - SteamWorld Dig (94% Positive on Steam Reviews) - Origin
EA is giving away a great game this time around. SteamWorld Dig is the predecessor to SteamWorld Heist which in itself is a great game although of course a different genre to this one.
This is a great platformer/exploration game which is definitely worth a playthrough.
If you have not got it, don't be rude to EA and accept their offer of a free game.
Those deals normally last several weeks but since this is not firm I would not delay getting the game if you want it.
