U.F.O. Tesseract

Help the friendly aliens get back to their dimension through the tesseract.

There are wars capable of traversing dimensions, as if it were a physical magnitude not subject to time or space. After the fever of the shoot 'em ups (matamarcianos), learned the lesson as it happens in the real live, also among the bad guys there are some good ones. Save the good-hearted aliens, return them to their home in the correct dimension !!!!!!!!!!!
