Have introduced teleporters to the levels where you can hold down the teleport button (LB - Xbox Pad) to go to activated teleporters.

Theres 4 teleporters on each level. As long as you've activated them (by walking through them once) you can then hold the teleporter button, no matter where you are on the map and you'll be teleported. Hold the teleporter button again and it will cycle through all the activated teleporters.

This makes it alittle easier and quicker. When dying it could become slightly tiresome walking to get back where you died etc. Now you can teleport. :)
