Today I changed the UI a little bit and fixed the open, close, unlock, lock actions which worked before. Since that I solved the pickup, drop, change actions with the inventory system, the only actions that left from the original game is firing weapons and priming explosives.

I worked also on the map renderer and implemented the fog of war for all units, which works also perfectly in the LOS mode. I added also a additional menu option to show / hide the tiles that are not in units fov. How all this works can be seen on the screenshots.
