The RuneScape/MechScape Hybrid was a strange hybrid between RuneScape and MechScape. It was discovered by fans that when you changed a part of the runescape coding from game0 to game1 it said mechscape above the loading bar. It was never logged onto but using the coding people have checked to see if there were any other differences but none were found. After about 3 months of it being discovered it was taken down and replaced with the RuneScape/StellarDawn Hybrid.
