Cataclysm: DDA Infected Ep. 6 - In Which Veru Gets Fancy
Cataclysm: Dark Days Ahead is a community developed free-to-play, open world, crafting, survival roguelike.
It's a tremendously well-fleshed out game which will likely be in development as long as people are playing
it. It's not beautiful, but it is great.
It has one of the most robust crafting systems of any game I've ever played, with great damage modeling and
a tremendous amount of realism features that I've seen in few games outside of Dwarf Fortress.
It tremendously fun to play and has a great community on the forums: http://smf.cataclysmdda.com/
and on reddit: / cataclysmdda
Download it here and enjoy: http://en.cataclysmdda.com/
I recommend you download the current experimental if you want all the features.
