Wizard with a Gun is an online cooperative sandbox survival game set in a magical wilderness wrought with dangerous creatures and arcane mysteries. Embark on a journey alone or with friends to collect, craft, and outfit your wizard however you see fit as you explore the unknown.

Demo is currently available. I'm not a survival roguelike kind of guy, but I always keep my eye out for one that might have the winning formula for me. And what I played in the demo makes me thing this might be the one. Check it out, it's got guns. And co-op.
