Hells Gate

Hells Gate, Originally known as Duck to Teleport, is a map that is inside a volcano with a lava floor.

The Giant can duck below the lava to teleport to the other side of the map to take the warrior by suprise

Trivia
If you get thrown high enough, or use the Rocket Ride ability to fly out the top of the map, you can actually just escape without getting harmed. You can stand on the outside of it and not die, and if you fall/walk off the edge you will fall forever since there isn't a death barrier
