Im HeavyDestroyer/BigCheese256, who will be handling the mapping and mission creation for Command and Conquer Tiberian Sun Redux! As announced previously by Taxikiller, the 1st release will feature the first two of Tiberian Sun's GDI Missions. But There will also be included 6 of the original Tiberian Sun Skirmish maps.
The list of Skirmish maps planned to be included are as follows:-
Grand Canyon (2-4 Players)
Grassy Knoll (2-4 Players)
A River Runs Near It (2-6 Players)
Kasey's Canyon (2-6 Players)
Forest Fires (2-8 Players)
Ice Cliffs (2-8 Players)
Unfortunately I cannot upload a video showing the preview pictures of these maps, but if you have Tiberian Sun, you can go in-game and see the previews + maps for yourself. If you don't have Tiberian Sun, then these maps will be a surprise for you on the release in November.
NOD will not be included in Command and Conquer Tiberian Sun Redux's first release, but a small amount of NOD units and structures will be added for the first two GDI Missions. However remember that NOD will not be available in skirmish mode.
Images of these maps/missions in-game will be uploaded when completed!
