Tunneler: Source is a Portal 2 mod based off a game on Roblox called Tunneler.
Tunneler is a game based off of Portal and Portal 2.
Tunneler: Source is currently in development and will be released as soon as we finish all that there is in Tunneler. Tunneler is not a recreation of Portal or Portal 2. Tunneler is not finished so that means Tunneler: Source will not be finished until Tunneler is finished.
In Epileptic Industries you are being tested by Axle. You make your way through the tests and find the Ecliptic Tunneling Device and it is NOT the same as the Aperture Science Hand Held Portal Device.
