By day, Carto City is a peaceful metropolis - parks, shops, everything you could need. But by night, robots roam, and they're more than happy to destroy anything squishy enough to pose a threat.

Chainwhack enemy robots to destroy them, build turrets to aid in fending them off, and chainwhack those to defend and repair them. Establish a hospital for healing, a DIY shop to chainwhack harder and keep your turrets maintained, and more. Most importantly, survive the night - the robots will succumb to sunlight at 6am sharp and you can use the wealth they drop to buy more turrets and upgrades!
