One more map constructed round a simple and at the same time brilliant idea: doors can be opened only energetic full-spheres familiar on Portal. The map is designed in such a way that to cope with the task without fast and harmonious actions here it won't turn out. Some doors need to be opened at the same time, and even to use a cube for monitoring of an energetic full-sphere. Well and to crown it all — Death Aboard wins our special prize for the most unexpected ending.
