On top of Skin Wars getting renewed for a fourth season earlier today, GameShowNetworkNews also has news to report about Hellevator and Chain Reaction. Both shows are "on the bubble" for renewal/cancellation.
For Hellevator, the production crew does not know if Hellevator will get a second season. They have not been told either way. Two episodes of Hellevator remain and air the next two Wednesdays at 8pm ET.
For Chain Reaction, GSN is going to analyze ratings over the new episodes coming later this winter (new episodes premiere December 18th 8pm & 8:30pm ET). GSN will make a decision soon-after.
