This Red Alert map has some revisions to it. Be careful, there are landmines that you can’t see buried in the center of the map near the walls and at the entrances, other than the two main entrances to the compound in the center of the map. “Fort Knox,” duh!
Anyway, you will see the revision includes a land bridge where there were no land bridges before. A little more tiberium was added, also. Have fun.
