I have released a demo for my 3D game : https://misterm.itch.io/omeara-and-the-salvation-barrier

The human colonies are decimated by the local population "the Deegan", only a few cities have survived. The city of Phoniant is protected by an energy Wall called "Salvation barrier".  This barrier stops the enemies to access to the city.

The population is exhausted, the great council has promised the arrival of resources as soon as possible. They are waiting for the human ships to arrive from the plant Svetla with some replenishment of food, weapons and industrial devices. Meanwhile to keep the power of the energy wall they need a mineral called Spaneg.

To collect the mineral outside the "Salvation Barrier" there is a team of people called "SG-Squadron". They use special robots powered with guns called "Collectors". The Mineral Spaneg is quite heavy, as much mineral you carry, less is the speed of the "Collectors".   Spaneg  is protected by "The Deegan" , more is the quantity of mineral.. more enemies will be to protect it.

Your name is Omeara a new cadet, they have assigned to you the "Collector 84".  Your mission is to collect Spaneg to protect the city. Remember more Slang you collect less will be your speed. If your collector is destroyed you can always run, but attention Deegan are quite fast and hungry.
